Dear Parth, I hope you covered your syllabus before. If I am talking about 2days study try to revise those selected topics which are most important you can easily analysis through previous year paper of jee and try to keep calm and tension-free because relax mind help you to recall whatever you prepared till now on exam day for sure, don't be panic just focussed to revised.

All the best dear   

Hello Parth!

It isn't possible to prepare well for JEE MAIN(b.arch paper) in just 2 days if you haven't studied at all.

If you have prepared your syllabus well and you want to just revise then you can go through all the formulas and some important previous year questions chapterwise.

You have to also practice drawing before the exam. Just have an oveeview of that and practice 3-4 diagrams from last year.

That's all you can do to gain the most you can.

All the best!
