Hello sarvesh

The PESSAT is not a tough examination to be worried for ..The 90% of the questions are solvable even by average students ,unlike JEE Advance entrance examinations which have so many unsolvable questions especially for mediocre. But the only problem in PESSAT exam is that you have to do the time management. Like in Maths there are some questions which can be solved only in 4-5 minutes and these questions looks so easy but when you start solving and  don't  get the answer, you may end up wasting your time.

So focus on time management also while completing your syllabus.

Hope this helps you.
