Format of O Level Additional Mathematics (syllabus 4049)

sitting for exam

The Singapore O Level Additional Mathematics (also called A- Math or Add- Math) consists of 2 papers. Any of the topics in the Add Math syllabus can come out in paper 1 or 2. But generally, if a particular concept is already tested in paper 1, then it will not be tested in paper 2. Also, all questions are compulsory, so don’t skip any topics when revising!

The Two Papers in O Level Additional Math (Syllabus 4049)

A summary of the weightage, duration and marks for paper 1 and paper 2 of Add Math are as follows:

a math format

Notice that both papers have equal weightage and are essentially similar in the number of marks and duration? 
The only difference between the 2 papers are the number of marks per question and the number of questions in the paper. In paper 1, there will be 12 – 14 questions of varying marks and lengths, up to 10 marks per question. In paper 2, there will be 9 – 11 questions of varying marks and lengths, up to 12 marks per question. All questions in both papers are compulsory.

How to prepare for Paper 1 and Paper 2 (O Level Additional Mathematics Exam)

You’ll have the exam for paper 1 first before paper 2. 


You would have noticed that there is not much difference between paper 1 and paper 2. Hence, you should revise the entire O Level Additional Mathematics syllabus when preparing for paper 1. You should also try both papers 1 and 2 of past exam questions from your ten-year series and prelim papers when preparing for paper 1 as what was tested in paper 2 previously could come up in paper 1.


Paper 2 comes after paper 1. Studying for paper 2 should be simply revision since you have already studied for paper 1. For paper 2, focus on the concepts that have yet been tested, since they are unlikely to ask the same type of question twice.
