The main advantage of Singapore Maths is the heuristics or special strategies that enable the student to understand complicated problem sums.

The major exam that all primary school students have to sit is the Primary School Leaving Examination (PSLE) and the Maths questions in this exam are some of the toughest they will ever encounter in primary school.
