PHYSICS:

Revising from a formula notebook,made yourself, having formulas and important points of each chapter is the best way.

But if you haven’t made it, just go through formulas & highlighted points in your notes.

Solve those questions which you weren’t able to solve in one go last time.

While solving questions always mark them according to their difficulty level & number of attempts you made to solve them, so that next time you solve only those questions which you weren’t able to do previous time.

CHEMISTRY:

For physical its just as same as physics.

for inorganic and organic you have to study ncert from line to line and then go to your notes and study materials if time permits and continue practising.

And write down all those reactions given in ncert all the naming reactions in organic chem on an A4 paper.It would help you to revise them quickly.

For boosting your confidence you can also practice AIEEE/JEE MAINS PREVIOUS YEAR QUESTIONS in both Physics and Chemistry.

Hope this helps !!!
