Solve only previous year gate question papers

This tip is very important specially when very less time is left in your GATE exam. In this time, you should focus only on solving previous year GATE question papers instead of your GATE study material and PSUs question papers. These question papers ISRO, DRDO, Coaching Material etc might have very difficult and challenging problems, but the focus of the GATE exam is on your aptitude, rather than the depth of the subject. Therefore in my opinion, its better to solve last 15 year GATE question papers multiple times rather than solving questions from other material.
