Did you know that more than 25% of the answers given in last year papers do not warrant full marks in the Open ended section? Why is it so?

The answer is simple… They are written by undergraduates who are not in sync with what PSLE standard requires. And yet MANY students and parents rely on it as if it’s the model answers… resulting in learning the WRONG concept of a relevant and precise answers.

Consequently, they are puzzled why they DO NOT attain full marks when they have done ‘well’ while practising the exam papers! And so, are past years papers still relevant?

Absolutely! It is in fact essential for students to practise and be exposed to a variety of question types.

You can now practise past years’ papers assured that the answers are modelled after what PSLE requires! In this way, the effort and time made to practise will yield significant improvement. That is because the TCR-infused answers has been carefully vetted by our team of teachers.

1) Why are the MCQ Answers not included in in this book?
