No More Recontract Voucher from Singtel? Best Phone to Recontract and Sell

It is an “open secret” last time that if you call the Singtel customer service hotline at 1688, they may give you a recontract voucher for you to get a new phone. In previous times it used to be as high as $100, then over the years it slowly reduced to $50. It seems that the voucher is gone now, for low usage customers (e.g. Combo 2 plan). That is, no more recontract voucher. That was my experience in September 2018. That being said, experiences may differ from user to user, you may still want to phone in to try your luck. The only reason I am still using Singtel is that the rest of my family is on the “Singtel Circle” plan.

Important Update: There is a new form of voucher, called the Singtel Referral Voucher, worth $100! Basically you switch to a new Combo Plan and get $100 off the phone.

Best Phone to Recontract and Sell Off

Traditionally, the best phone to recontract and sell has always been the latest iPhone. This is based on the strong demand for iPhone. For instance, as of now, the most popular seems to be iPhone XS, Gold color, 256 GB. Do take note of the color/storage size as unpopular combinations may fetch a lower price. At the time of writing, recontracting and selling an iPhone may earn as much as $300 or more (buy at $1338 and sell off at $1640).

How to get Singtel Voucher (2019 onwards Method)

Are you still looking for the elusive Singtel Discount Voucher to offset your phone purchase? Do not bother to call 1688 anymore, that is the old-school method that does not work nowadays (you can still try if you want, you will find it hard to even speak to a human Singtel operator).

The new method is to use the Singtel Referral Voucher which is worth $100. Click here to go directly to the official Singtel website where your $100 voucher will be applied automatically.

Poll: Opinion on Fewer exams for Primary and Lower Secondary Students?

I have added a poll to see what readers think of this new proposal?

Actually mid-year exams and assessments may have a role as a “buffer” to reduce the weightage of the final exam. Removing mid-year exams actually has the effect of transferring more weightage to the final exam, making it more stressful? It boils down to whether people prefer a grading based on 100% weightage for final year exam, or something like 30% mid-year, 20% assessments and 50% final exams. Based on personal experience, many students (including myself) do prefer having a mid-year exam so that their results of the year is not entirely based on the final exams.

Also, for people who are natural procrastinators, who tend to do things at the last minute (possibly around 90% of the human population?), cancelling exams at the Primary 1 and Primary 2 level may end up causing a false sense of security, leading to a frantic panic attack at Primary 3? As a tutor, I receive numerous tutoring requests as late as September/October (for the final year exam), hence I know that numerous students/parents tend to panic at the last minute due to procrastination.

Possibly a worst case scenario that can end up is that the child does not learn well the fundamentals during P1 and P2, and this is undetected by his/her parents due to the absence of exams. Suddenly at P3, the reality is unveiled and it comes as a sudden shock. The P3 student has to catch up with the two years of fundamentals (P1 & P2) quickly before it is too late, as many subjects are cumulative in the sense that P3 topics relies on previous knowledge of P1 and P2 material.

Nonetheless, it is a new policy and it is good to see some changes coming that is intended to reduce the stress of young students. The time “saved” from doing exams can potentially be channeled into learning something new that is not found in the traditional syllabus. Scrapping the class/level position is good, there is no need to be obsessed with being “first” in class at such a young age. Possibly a percentile grade is still necessary for parents to gauge how their child is doing. Keeping PSLE is also good, despite PSLE being stressful it is actually a meritocratic system that theoretically allows a talented student from a poor family to rise to the top.

The changes will be implemented in stages, beginning with the removal of all weighted assessments and exams for Primary 1 and 2 students from next year. Weighted assessments, said MOE, can take various modes such as class tests, presentations or group projects.

Currently, Primary 1 students do not have exams, but weighted assessments are conducted throughout the year. Primary 2 students now have weighted assessments throughout the year, as well as a year-end exam.

Secondary 1 students will also no longer have a mid-year examination from next year. From 2020 and 2021, this will also be removed for Primary 3, Primary 5 and Secondary 3 students.

Chope.co is a restaurant reserving website that provides diners with benefits and rewards for reserving their seats at restaurants! “Chope” is a Singlish slang for “reserving a seat”. Reserving a seat is often important since the majority of  Singaporeans eat out on weekends/weekday dinner/and special occasions. This means that the restaurant is crowded during those popular times, and failing to reserve a seat may mean long waiting times or even worse, not finding a seat.

Cool Fact: Cockroaches are becoming Endangered/Extinct in Russia (and other post-Soviet states)

Quite amazing that the cockroach, which is one of the most hardy animals, is actually becoming endangered/extinct in Russia? Possibly the cold weather has something to do with it, in addition to modern technology. Any Russian readers would like to confirm that this is true?

A side note that in tropical Singapore, cockroaches are far from endangered despite frequent fuming and spraying of insecticides, usually at the rubbish chutes. In fact, in most HDB apartments, spraying insecticides at the rubbish chutes actually may increase the number of cockroaches in the house due to those escaping/flying from the rubbish chute where they ordinarily live.

Source: https://en.wikipedia.org/wiki/Depopulation_of_cockroaches_in_post-Soviet_states

Quote: A mass depopulation of cockroaches has been observed since the beginning of the 21st century in Russia and other countries of the former USSR. Observers have noted a quick disappearance of various types of cockroaches from cities and towns in Russia, AzerbaijanKazakhstanUkraineMoldova, and Belarus.

From PSLE 124 to PhD A*Star Researcher

Source: A-star Official Website

For those familiar with the Singapore education system, you would know that PSLE 124 is not a good score by any standard. Yet Dr Vincent Lim, through his hard work and perseverance, managed to push on and graduate from university with first class honours, eventually earn a PhD and land a job at the prestigious A*STAR’s Institute of Medical Biology.

I believe the chances of this happening is truly rare in Singapore, possibly even rarer than striking 1st prize in TOTO. Singapore’s education system is known to be not too forgiving, once you make a “slip”, it is hard to get back onto the fast track. It must have taken tremendous courage, perseverance and hard work to overcome the odds to achieve this.

Truly amazing! Do share this to encourage those with children not doing too well in primary school. Certainly, late developers do exist and if given the right environment and nurturing support, they can blossom to reach their fullest potential.

Inspirational quote:

My advice for people who didn’t do well in school is this: it’s never the end. Society may sometimes seem to say: ‘This is your one job, you need to do well in school!’ But that’s not true. There’s never just one job; that’s not the reason you were born for.

Grades are not the most important thing. It is merely a stepping stone; if you’ve got no stone to step on, then run, jump, and climb. What is important is to never give up on yourself and to always keep your options open.”

-Dr Vincent Lim


Get Official Ivy League (U Penn) degree online

Note that this is the first time an Ivy League university is offering a full degree online. Previously, some universities do offer some module credit or unofficial courses online, but this time University of Pennsylvania is offering its new bachelor of applied arts and sciences degree online.

Do check out their official course page here: Penn LPS Online.

So far I don’t see any restriction on nationality, that means possibly Singaporeans can apply too.

Some pointers that you may want to take note:

  • If post-secondary credentials are from an institution outside the US, transcripts must be evaluated on a course-by-course basis by World Education Services, Inc. (WES).
  • BAAS students are only required to come to campus for two extended weekends as they complete the program.

Varignon’s Theorem (Surprising Geometry Theorem)

I first learnt it from Quora:

“Take any quadrilateral. It doesn’t have to be any special kind of a quadrilateral. Then connect the midpoints of its sides.

Surprisingly, you will always get a parallelogram!”

Quite a nice result. Some googling revealed that the name of this theorem is called Varignon’s Theorem.

RI vs HCI vs NUSH

Many excellent P6 students will be spoilt for choice at this stage, as they have been accepted by multiple schools under the DSA. Here are some views on RI versus HCI versus NUS High, which are the top 3 choices for boys strong in math/science:

RI emphasize “all-rounder” and “leadership” in their culture. My personal experience is that it can get a bit competitive since many people there are literally good in all forms of studies (all subjects in humanities/sciences/languages maybe except Chinese), sports, and music, etc. The culture is similar in RGS. I find that there are some cultural and personality differences between the typical RI/RGS student and the typical HCI/NYGH student.

The good points are that RI does have a lot of activities and opportunities like overseas school trips, top coaches for most CCAs, etc, that many schools don’t have. Also, many RI students are successful in securing government scholarships for top universities since their portfolio will be built up in a balanced way during their studies; there are many Community Involvement Programmes and other activities to boost the student’s portfolio.

Certainly NUSH and HCI are very good schools too. Possibly advantages of NUSH is greater focus on science/math and advantage of HCI is greater emphasis on Chinese culture and tradition, which is useful as China is becoming a world power.

Sir Michael Atiyah to reveal his awesome proof of the Riemann Hypothesis

Source: https://twitter.com/HLForum/status/1042670700652318720

According to the official twitter account of the Heidelberg Laureate Forum, Sir Michael Atiyah will prove the Riemann Hypothesis during the talk on Monday Sept. 25.

According to him, it is a “simple” proof, based on previous work by von Neumann, Hirzebruch and Dirac. It is likely to have some relation to theoretical physics, since Dirac is a theoretical physicist. It has been rumored for quite some time that the Riemann Hypothesis is related to theoretical physics.

The Riemann Hypothesis is the most famous and most difficult problem in mathematics. Sir Michael Atiyah is a 89 year old gentleman currently. It will be really groundbreaking if the Riemann Hypothesis is found to be successfully proved.

20% of Singapore’s workforce will be “displaced” by 2028 due to AI

According to the article by Today newspaper, around 20.6% of Singapore’s workforce will be “displaced” by 2028 due to technology and AI. This is quite scary news by the reliable newspaper Today. Although “displaced” is a tricky word and need not mean jobless or retrenched, nevertheless students should be mindful of this when they choose their major in polytechnics and university. Many esteemed jobs like accountancy, may or may not still be viable in 2028, as robots AI may likely have progressed to such a stage that they can easily take over human jobs. Non-degree jobs such as insurance agent and property agent may also be at risk. The bottom line is that if AI has progressed to the stage of being cheap and good, the big bosses will adopt it readily to lower their cost and maximize their profit.

Concerned parents and students should certainly read the below book, especially those who are about to choose their major in polytechnic or university. It is a “New York Times-bestselling guide to how automation is changing the economy, undermining work, and reshaping our lives”. As the saying goes, 男(女)怕入错行, the greatest fear of men (and women) is to enter the wrong profession. Checking out the future prediction of experts like Martin Ford is certainly a good idea. Imagine studying 4 years for a job that suddenly becomes extinct in 2028.

It is not an accident that Computer Science (and related subjects) is now one of the top and most popular majors in Singapore and many countries.


Rise of the Robots: Technology and the Threat of a Jobless Future

Source: Today

Workers in Singapore will be hit hard by technological disruptions with the Republic’s labour market set to face the largest degree of job displacement regionally in the next decade, based on a study on the impact of artificial intelligence (AI) on workers in six South-east Asian economies.

The new study by technology company Cisco and economic forecasting agency Oxford Economics also found that Singapore will have to confront the biggest mismatch between skills and jobs created among the countries in the region.

The findings were released on Wednesday (Sept 12) on the sidelines of the World Economic Forum on Asean (Association of South-east Asian Nations), a high-level gathering on innovation and entrepreneurship in Hanoi.

Data showed that about one-fifth of Singapore’s full-time equivalent workforce (20.6 per cent) will have their jobs displaced by 2028. This is higher than the figures for Vietnam (13.8 per cent), Thailand (11.9 per cent), the Philippines (10.1 per cent), Indonesia (8.1 per cent) and Malaysia (7.4 per cent).

Do check out this new website (http://lifebeyondgrades.sg/), which as its name implies is about emphasizing that school life is not all about grades, even in Singapore. It is kind of an official website, being funded by National Youth Council (see their FAQ.)

It is good that nowadays parents, teachers and the education sector has started to realize that grades is not everything in life. The FAQ section is very interesting and actually kind of reveals the future direction that Singapore education is heading towards. A few key points:

  • “Why can’t we do away with the PSLE” –> Implication: PSLE is never going to be scrapped, at least not in the near future.
  • “Why can’t we do away with CL2” —> Mother Tongue is here to stay for the time being.

The most addictive theorem in Applied mathematics

Chinoiseries2014's avatarMath Online Tom Circle

What is your favorite theorem ?

I have 2 theorems which trigger my love of Math :

  1. Chinese Remainder Theorem:韩信点兵, named after a 200 BCE Han dynasty genius general Han Xin (韩信) who applied this modern “Modular Arithmetic” in battle fields.
  2. Fermat’s Last Theorem:The Math “prank” initiated by the 17CE amateur Mathematician Pierre de Fermat kept the world busy for 380 years until 1974 proved by Andrew Wiles.

Note 1: Lycée Pierre de Fermat (Classe Préparatoire) happens to be my alma mater named after this great Mathematician born in the same southern France “Airbus City” Toulouse.

Note 2: His another Fermat’s Little Theorem is used in modern computer cryptography.

Win Mercedes-Benz CLA 180 Coupé by donating to charity

This charity is featured in Straits Times and the New Paper. Basically, you buy a $20 ticket (comes with T-shirt) which will go to a charity of your choice. The main point is that there is a chance to win a Mercedes-Benz. Most youngsters in Singapore can’t afford a car, not to mention a Mercedes, so this is a great prize. (If you don’t drive, you can sell the car.) Also, foreigners (excluding US citizens) can take part (see their FAQ for more details)

Currently, there are only 577 tickets purchased, so your chance of winning is 1/577 which is quite high compared to other lotteries like 4D or Toto. The draw date is 02 Nov 2018, which is quite close. They will apparently go ahead with the draw even if their target number of tickets (50000) is not met.

WiFi Password = Integral Answer

tomcircle's avatarMath Online Tom Circle

China Nanjing Aviation University set the WiFi password as the answer of this integral (first 6 digits).

Can you solve it?

Answer : Break the integral (I) into 2 parts:

I = A(x) + B(x)

$latex A(x) = int_{-2 }^ {2} x^{3}. cos (x/2).sqrt{4-x^2}dx$

$latex B(x) = int_{-2 }^ {2} 1/2.sqrt{4-x^2}dx$

A(x) = – A(-x) => Odd function
=> A =… since its area canceled out over [-2, 2]

B(x) = B(-x) => Even function
$latex implies B(x) = 2.int_{0 }^ {2} 1/2.sqrt{4 – x^2}dx$
$latex implies B(x) = int_{0 }^ {2} sqrt{4 – x^2}dx$

Let x = 2 sin t => dx = 2 cos t. dt

x = 2 = 2 sin t => sin t = 1 => t = π/2

x = 0 = 2 sin t => sin t = 0 => t =…

$latex B(x) = int_{0 }^ {pi/2} sqrt{4 – 4.sin^{2} {t}…

Alibaba launches scholarship programme in S’pore with generous funding

Source: Today Online

Alibaba has partnered with NTU to launch a scholarship program on computer science topics like artificial intelligence, data analytics and cloud computing.

The scholarship funding is very generous: monthly salary of 5,000 SGD for 4 years, with other benefits like CPF, insurance, etc. This is at least 40-50% more than most PhD scholarships in Singapore. Each PhD candidate will also have the opportunity to be mentored by at least one supervisor from his/her enrolled university and one co-supervisor from Alibaba.

It sounds like a very good opportunity for those interested in IT. Hopefully Alibaba will set up more of such facilities and programs in the future.

How to type Chinese characters in LaTeX (on Mac, using TeXShop)

This is one of the easiest ways to type Chinese characters in LaTeX on Mac, using the default TeXShop editor. (If you know of an easier way, please let me know in the comments below!)

I have tried for hours, experimenting with different packages, before “discovering” the following steps. Hope it helps!

Step 1) Add “\usepackage{ctex}” to the beginning of the document. This will load the main package ctex.

Step 2) It is very important to save the LaTeX file in UTF-8 format, otherwise all Chinese characters will appear as question marks. The preferred way to do this is via:

TeXShop > Preferences > Encoding = Unicode (UTF-8). (see image below)

This will “permanently” set the format as UTF-8 by default. If you don’t do this, an annoying thing that can happen is that your TeX file reverts to “non-UTF8” upon saving. That means, the Chinese characters may appear correctly at first, but once you re-save the file, all Chinese characters become question marks again.

Alternatively, if you don’t want to set UTF-8 as default, you may add the following line to the very first line of the TeX document:

% !TEX encoding = UTF-8 Unicode

This will make TeXShop remember to save it in UTF-8 format every time.

Step 3) Just type Chinese characters directly into the LaTeX file. No “wrapper” is needed around the Chinese characters.

Step 4) When you compile the document, be sure to compile it by XeLaTeX. You can select this option next to the “Typeset” button. If you compile it using normal LaTeX, you will get the following error:

“Critical ctex error:”fontset-unavailable

CTeX fontset `fandol’ is unavailable in current mode.”


For Windows users, I suppose the above steps still work. I have not tried it personally though. Other packages may work only for Windows/Mac specifically since each system have different preloaded Chinese fontsets.


Hyperref Problems with Chinese TeX

A known problem is that hyperref does not work well with xetex or xeLaTeX. This may be a problem if you are using xeLaTeX in conjunction with Hyperref. The proposed solution is to use the option

\usepackage[xetex]{hyperref}

Note that if you have multiple options for hyperref, xetex should be the first of all the options.

TeXShop opens Chinese documents showing Gibberish

This is quite common, especially if your Mac or Windows system is not set with Chinese as primary language. A proposed solution (there may be a better solution) is to:

  • Set the primary language of your Mac / Windows as Chinese. The entire system, including all your taskbars, icons should be in Chinese.
  • Open the TeX file containing Chinese characters with Notepad/TextEdit, not TeXShop. Ideally, the Chinese characters should display ok there.
  • Copy and paste the entire file from NotePad to TeXShop.
  • Add the line % !TEX encoding = UTF-8 Unicode at the start of your TeX document to ensure that the Chinese characters will continue to stay there after closing of the document.

Chinese Lessons in Singapore (Video)

Source: How has Singapore’s Chinese Language syllabus evolved?

Read more at https://www.channelnewsasia.com/news/singapore/singapore-chinese-syllabus-changed-back-to-school-10664986

Quite interesting to see how Chinese lessons are like nowadays. To be honest it doesn’t seem much different from 10 years ago? One aspect that has changed is email writing. Nowadays it is rare to write letters, hence the modern syllabus focuses on writing emails instead. Also more multimedia like videos are being used.

One notable statistic is this: “At Tanjong Katong Secondary, Mrs Lee said about 70 per cent of students come from an English-speaking background.” This is a very high percentage compared to the times of the past. To master Chinese is increasingly hard for such students, great effort needs to be put in for improving their command of the Chinese language.

Notable Quotes:

She agreed that it can be difficult at times to speak Mandarin fluently. But she makes it a point to practice by having conversations in Mandarin with friends and family members, and exposing herself to Chinese shows.

“I enjoy it when the teacher shows videos in class,” she said. “I understand how the characters feel, and how they speak. I can learn a lot from the way they phrase their sentences.”

GEP PSLE Discussion

It is well known that GEP students spend Primary 4 and 5 doing miscellaneous stuff that appear to be not directly related to PSLE, yet majority of GEP students score 250 and above for PSLE. Hence, the main question is:

Does GEP help PSLE?

Kiasuparents has a very robust discussion going on, and here are some of the insightful snippets. For the full discussion, check out the Kiasuparents forum.

Summary: GEP only starts preparation for PSLE at P6 April (!!) For PSLE, students need to be exam smart and be careful to answer “according to the marking scheme”. GEP teaches many higher level concepts which are not in the syllabus, for example “good bacteria”. Content wise, GEP English/Math/Science at P4-P5 is already at or surpassing the mainstream PSLE level. For Chinese/Mother Tongue, there is not much difference between GEP and usual syllabus.

Viewpoint 1: GEP helps PSLE but not directly

bhcbl wrote:After DS 3 years journey in the program, my thoughts are as follow:

– Does GEP help PSLE … NoNot directly. I do think my son did better in PSLE than he would have done in his previous school coz his classmates were stronger, and because the teaching suited him. Revision was short and sharp, and he didn’t have to do too many revision papers
– Does GEP help DSA … No (definitely not directly under the new policy, maybe the exposure in broader Math and Science help HDP in a way) No, because GEPpers don’t have a special pass to DSA any more. But the GEP education does provide more opportunities to develop knowledge in various areas that could help in the interviews and portfolios
– If we get to choose again, will we still opt to be in the program … yesAgree with everything below
Stretches … eg. Book review on books for older reader, more difficult Math concept …
Broaden … eg. Ancient civilizations, magic square, ancient number system, history
Self-learning … various research and projects (at least 4-5 a year)
Time management … homework, projects, research, self-studies
Filing … they have no textbook
Also, I think it was just alot more fun for DS (after some confusion in P4 while getting used to the system). He enjoyed classes, enjoyed his classmates (mostly), and I loved the smaller classes and the opportunities for various additional classes / camps etc.
So as you can see, in the three years, most of their times are spend on thing that have nothing to do with PSLE or PSLE prep until around P6 Apr.

Think about the following: in English, they learn to infer and read between the lines, but in PSLE compre, if you do that likely you will get marks deducted; Have parents experience the problem of teaching your child Math … using algebra to solve, and then convert to the model method to explain … this is some of the things that Gep students need to go through for Math PSLE (imagine for a 12 years old child). Or PSLE syllabus issue … if you ask any Gep student whether bacteria is good or bad … they will tell you both and give you a good list of examples … but too bad that is not in PSLE syllabus: Bacteria is bad (marks likely deducted if you start talking about bacteria is good).
Our take: the GEP system is a great system, but the problem is in the past they don’t need to rely on PSLE because there is DSA, but now they have to with the change in MOE policy. It is quite cruel to do that to a child… teach them more boarder and advance stuff but in exam ask them to forget about all these.

To us, we think that education is a journey, while PSLE is just a small part of the journey. Therefore, we will still go for GEP if we could choose again. Lastly, you will see most GEP students don’t need to adjust to secondary school: 8 subjects … they are already used to very pack schedule; additional topic like history, literature, geography … these are covered in one way or another in their 3 years program (but not tested in PSLE).

So hope that this could help you in your decision in your child education journey. If you are hoping that GEP mean PSLE or DSA or good secondary … under the new policy, you may be disappointed. If you are hoping to have a challenging and stretch program for your child … likely you won’t be disappointed.

Viewpoint 2: GEP definitely helps PSLE (and DSA too)

(by entei17) Does GEP help PSLE

Yes, definitely. In fact two years in advance. If you look through the learning scope and common tests papers for English, Higher Chinese, Maths and Science, the P4 Geppers are already doing P5-6 stuff in the mainstream.

English already has situational writing which is not introduced till P5 mainstream. Vocabulary and Grammar are pitched at P5-6 or maybe secondary levels. Comprehension format is very similar to PSLE, except that the passage is lengthier and more difficult to understand (need inference) than PSLE. As revision and practice for common test, I let my child do past year PSLE papers instead, because the P4-5 revisions books are not compatible. All the Extensive Reading List assignments, Single Shard literature, Synthesis and Transformation etc also help to build up their English foundation, so they can read more and advanced their appreciation of the language. Some of the assignments are an overkill, requiring a Herculean effort, or mission impossible. They have a comprehensive English curriculum, but I’m not sure whether all the Geppers could keep up.

Higher Chinese uses the same textbooks as the mainstream i.e. 生字 are similar, but the test/exam paper formats are similar to P5-P6/PSLE. Geppers would have no problems adjusting to the PSLE requirements. As GEP selection test only tested English, Math and General Ability, Geppers’ average Chinese ability are generally on par with the mainstream. Those that are good in English are generally not good at Chinese, although there are a handful who are good at both, or in all the subjects. I don’t have any evidence to back this up, but one reasons why some Geppers who didn’t score well in the PSLE are probably pulled down by their Chinese.

Maths are pitched at P5-P6 mainstream topics, but enriched and more interesting. I’ve seen many mentioned about Ancient civilizations, magic square, ancient number system, history. These are all covered over a week or only a few assignments. Most of the worksheets are still the usual topics but pitched at a higher level that stimulates their thinking. The only problem is Geppers think faster and have a tendency to skip/leave out some of the workings, which may prove a problem to the marking scheme in the PSLE.

Science topics follow the PSLE syllabus and the usual topics, enriched and deeper thought. We use P5/PSLE questions for revisions. The key here is (no pun intended) is still keywords and key concepts when answering open-ended questions, which is not dissimilar to the mainstream and PSLE requirements.

If whether GEP prepares PSLE every single day from P4-6 by drilling them to do past year papers after past year papers, then clearly they don’t. They spend a lot of time doing other stuff which indirectly raise their ability – maybe it helps in PSEL, maybe it doesn’t.

– Does GEP help DSA

DSA based on Sports/CCA are irrelevant here unless GEP’s heavy workload deprive them time to train or participate more actively, which could be a consideration. If not GEP and mainstream compete evenly based on their sports achievement.

Based on history, the majority of Geppers score 250 and above. Some don’t because of their mother tongue (as mentioned above), which even if they are in the mainstream, won’t be any different. Some are simply misclassified into the GEP – no matter what the GEB says about their tests. Parents know their child best whether they have the ability.

So even without DSA, for those scoring 260 and above they would still get into the top IP schools. The only one you have no choice but to try for DSA is NUS High, because there are very few places left in the posting exercise after the PSLE. However, this may also backfire on the Geppers because the schools know the Geppers would score high, and therefore still come to their school, and therefore may not need to give you a CO. With government’s push for social mobility and anti-elitism, they may just want to mix it up a bit more in the elite schools and therefore less Geppers as the first cut – just pure guess, since PSLE would still bring back the higher scoring Geppers anyway through meritocracy.

But compare to the mainstream, does GEP equip you better to do DSA? I think very so, as GEP affords you opportunities to participate in the MO, SO as well as many other competitions, and as early as P4, which may not be the case in the mainstream. So you have a better chance to build up your academic portfolio.

Do Not Press This if you are Overseas (Singtel Customers)

If you are an Apple iPhone user, and from Singtel, remember not to press “OK” when you see this message: “iMessage: Your carrier may charge for SMS messages used to activate iMessage.”.

 

 

 

 

This message appears when you swop SIM card, turn off the phone, or in various other situations.

Singtel treats this as “International SMS”, and can charge a fee for it. I got hit with a $5 fee as I was frequently swopping SIM cards (to check for any SMS received on my local card). The charges appear as “AutoRoam (PAYR) SMS”.

Solution

The solution is to press “Cancel” whenever the message pops up. If you are already get the charges by Singtel, you can try calling in/online chat with them to waive the fee. I managed to get a “one-time waiver” which will supposedly occur within two billing cycles.

Where to buy dumplings (饺子) in Singapore

新加坡哪里有卖饺子

Dumplings (饺子) is a staple food in Northern China. However it is rare to find it in Singapore. Often in NTUC Fairprice, or other supermarkets, Gyoza (Japanese Dumplings) or Korean dumplings can be found, but not Chinese dumplings. Making your own dumplings is possible, but very time consuming.

Recently I found out about “Yongle Kitchen”, which sells authentic Shandong style dumplings. Check out their video below, it looks very professional.

The recommended way to buy their dumplings is through Qoo10Click here to enter their Qoo10 Official Shop!

Morse Inequalities

Let X be a CW complex (with a fixed CW decomposition) with c_d cells of dimension d. Let \mathbb{F} be a field and let b_d=\dim(H_d(X;\mathbb{F})).
(i) (The Weak Morse Inequalities) For each d,

\displaystyle c_d\geq b_d.
(ii)

\chi(X)=b_0-b_1+b_2-\dots=c_0-c_1+c_2-\dots,
where \chi(X) denotes the Euler characteristic of X.

Proof:

The proof is by linear algebra (see Hatcher pg. 147).

By rank-nullity theorem (秩-零化度定理), \dim C_d=\dim Z_d+\dim B_{d-1}.

By definition of homology, \dim Z_d=\dim B_d+\dim H_d.

\therefore c_d=\dim B_d+\dim B_{d-1}+b_d.

In particular, c_d\geq b_d.

Taking alternating sum gives \displaystyle \sum_d(-1)^d c_d=\sum_d(-1)^d b_d.
