It is well known that the bell curve is applied to the O Levels result. The most notorious example is E Maths, where 90+ or high 80s is required for the top grade of A1. The traditional mark of 75 is only enough for B3/B4 in the actual O levels.

According to multiple users on Reddit, the bell curve estimate for Maths in 2016 is:

**Emath: 95**

Estimated a 92. Was pretty confident that I’ll get an A1. My math teacher even said that it’ll be ~88 due to the difficulty of the paper. Ended up with an A2 zzz.

**Amath: 90**

Paper 1 was tricky but paper 2 was manageable. Same thing as above. Estimated a 87, but got an A2.

“2015 O levels, I got double A1s for both maths. **My E-Math estimate is on 96% and A-Math on 90%.** The curve on E-Math is far steeper than A-Math, but if you wanna get the double A1s, grind and aim for perfection.”

For the A2/B3 grade, it is less demanding, but still significantly above 70:

Bellcurve is always unfavourable to E Maths student but kinda favourable to A Maths student.

I think I only got **78-79% for E Maths** and I got **A2** in the end.

While for **A Maths**, I know I only got** 60-64%** and in the end **B3**.

Other sources like Kiasuparents gave the following estimate:

Even if people minus a lot of marks for working… The emath A1 won’t be less than 85.. The paper is too easy. That’s why They moderate the bell curve up by so much.

And not only my teachers, but teachers in other schools as well have told their students that **if they think a score of ~75 can get them an A1, they should b expecting a B3/B4 instead**.
