There is a lot of similarity between 11th physics & 12th physics section. Both involve studying too many concepts and equations and problem but in examination, the question that you get are not easy to solve. To know how to approach these questions, the best way is to practice questions at home throughout your preparation time. In the time table make sure you have kept time for solving to many questions. Even if you take up 15-30 questions every day from books, you will be ready for the exam as well as be confident about NEET.

NEET is an examination for National level. Besides the clear concepts, it also demands in-depth knowledge of the subject. For that, you should refer to good books. This will help you with clearing concepts as well as will make you more knowledgeable. Also, you can refer to YB study material which covers the whole syllabus with interactive design and allows you to practice questions.
