1. If you have studied well for 2 years(I mean, confident of scoring above 200 or 250), then go for revising notes(specially in chemistry), all the formulae should be on your tips and solve at least one full syllabus paper everyday. Use an OMR and sit in the exact duration of paper(and use 15–30 minutes less than 3 hours). Note down all your silly mistakes and read them before going to the exam Hall on 8th April. You have prepared well but you need to be confident and motivated. Read NCERT, specially chemistry. Focus on covering more problems than tough ones
2. If you have been fighting for last two years but still aren't confident (i.e. you expect to score around 150 or so), then focus only on notes for now. Don't try anything new. Solve past papers for sure. Your focus should be more on making out maximum marks out of a paper. You are more prone to silly errors, and so make sure you attempt the paper in the most efficient way possible. Again, stay motivated.
3. If you aren't even sure of making the cutoff (expected score 100 and below), then I'd recommend seeing the last five years papers, figure out what are the topics you can score in, and study them on a very basic level. Try having a balance between what's easy and marks fetching. Topics like Rotation amd Electrostatics might bowl you over, but topics like Waves, Quadratic equations and Inorganic Chemistry can save you. Study them, and again from NCERT/basic notes. Don't go for stuff you can't get.

Staying motivated, solving papers and revising notes(and NCERT) is recommended for all.

Pro tip: Don't aim for 360, as you will most likely screw the paper, I don't want my record to be paralleled anytime soon :p
