For physics you must completely stick to ncert . If you have solved the complete ncert then you can also try ncert exemplar of physics. Besides you should periodically practice mcqs for physics, for this you can use Dinesh publication book. If you still have some time left and want to practice more then go for H c verma. If you do this much , then i am sure you will definitely get a good rank and a goid government college.

Best wishes.
