Hey there

First of all congratulations for your 10th marks and since you are a bright student the first thing I want to advise you that try maintain your marks. For physics in 12th let me tell you many students feel this subject tough. HC Verma is the most standard book and I advise you to go through it thoroughly. Please join a good coaching if your school has lower standards than jee because you are not going to get a second chance as if you drop there will be a lots of tention in your mind.

Good luck
