Hello Vivek. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

First up, sorry for the delay in getting back to you. I hope to answer your query to the best of my ability. 

First, please take note that the syllabus of PESSAT will be set according to the NCERT / CBSE syllabus of class 11 and 12. So to prepare for Physics, Chemistry and Mathematics subjects, you just simply need to follow the topics listed against them in the CBSE syllabus.

Also there is a grammar section. For this, I would advice you to just pick a good grammar book to strengthen your basics.

According to me, if you just papered well for your JEE Mains, PESSAT will be much easier to crack. 

I would like to direct your attention to this link for a sample paper of PESSAT:
