The books which I used for JEE -

PHYSICS -

HCV ( for practicing )

DC Pandey ( for theory and concepts )

Your coaching packages ( never underestimate them )

MATHS -

ARIHANT SERIES ( all of them of Indian writers , maybe you can leave the alzebra one ) I consider them god of jee maths , follow them by heart you will see the magic .

Your coaching package , if needed but the upper point is sufficient .

CHEMISTRY

for chem there is no specific book , I suggest you should follow your teacher .

and solve your coaching packages .

But if you really want for org - Solomon and fryhle , phy - RCM .
Also

• Mastery over the concepts is what contributes to success.

• Study daily for the hours fixed by you  so you might not suffer from pressure at the eleventh hour. Stick to your time table.

• I think, you should study for the advanced as soon as you grasp the concepts. First practice the JEE mains level questions and then try solving the questions of JEE advanced. Otherwise, I don't think you would be able to get ample of time separately for the JEE Advanced.Why to take the JEE Avanced as a havoc if you are understanding the concepts well?!
• Don't underestimate the easy questions. Keep practicing them too.

• Have discussions with your friends.

• Read interviews of toppers to know their strategy.
• Keep yourself motivated.

PRO TIP -

Never get demotivated .

Do not waste time in searching for extra books , the ones I have mentioned are sufficient or maybe you should ask your teacher .

Just be confident always!

All the best .

Hello Aniket, i suggest you to follow this sequence maths>chem>phys or chem>math>phys. Because maths and chemistry is little bit easy when compare to physics.
