This is a handy tip to search for Free Exam Papers on Google.
(Note: Google is very powerful, but it can only search for exam papers that are already online in the first place)
Since most exam papers are in PDF format, we can restrict our search to PDF files by adding the phrase “filetype:pdf” to the Google search.
For example, searching “hwa chong maths sec 2” in Google does not yield many exam papers.
Searching “hwa chong maths sec 2 filetype:pdf” returns a much better result, including some worksheets and test papers.
