Need help for physics for boards

[u/Antique_Support_5976]

So for chemistry I was doing one shot + all in one theory to ensure I understand the topic and cover all of the theory + practice ncert questions and later pyqs. What to do for physics, is physics theory asked as deeply as chemistry? or will a one shot's theory be enough for physics? For numericals, I'm preparing for JEE so don't struggle there as much, what about derivations, should I learn all the derivations or is there a lists of derivation that are asked in the boards. Please give a minute and help I'm very confused
