Are you frustrated by the endless types of problem sums?

Is your child still not achieving the desired results, despite putting in hours of practice?

If that is the case, I urge you to read this.

It is not about the number of questions that your child does…

It is about the right types of questions that your child does.

 A PSLE Math problem sum may involve Whole Number, Fraction, Ratio and Percentage…

But the concept and heuristic tested are the same. 

The faster way to see breakthrough improvements is to practice not by chapters

But to do targeted practice by concepts.

Hence. we have compiled the 20 must-know concepts and created more than 100 exam-based questions for your child.

Here is how your child can use this eBook:

1) Read the notes and examples given at the start of each concept.

2) Practise the questions to master each concept.

3) Use the solutions to check the answers.

4) Watch the videos if your child is still confused after looking at the solutions.
