Regular studies, practice and revision are extremely important in order to score well in competitive exams.If you aren’t too comfortable with self study, join a coaching institute to make sure you are putting in all your efforts in the right direction. NEET cut offs are quite high and getting a little extra help can be of great use.
Use NCERT textbooks as your main study material. A number of questions in the NEET questions paper, especially in the biology section, are directly or indirectly from NCERT books. Other books you may use for reference are Pradeep ( inorganic and physical chemistry), DC Pandey (physics) and MS Chauhan (organic chemistry). However, too many books for reference may lead to a lot of confusion in your basic approach strategy. Do a little research to find out the most popular reference books and stick to those.
Make sure your understanding of basic concepts in biology, chemistry and physics is clear. NCERT textbooks are great for understanding the basic concepts in these fundamental subjects.
Divide your hours wisely between all the subjects since all of them are equally important in order to do well in NEET.
Practice is the key. The more you practice, the better. Previous years question papers and mock tests will help you a great deal.
Find out which self-preparation strategy will work the best for you. Think about your strengths. Do you have good analytical skills or are you better with concept retention? Plan your study method on the basis of your strengths.
Avoid rote learning. Memorizing everything will only help you to a small extent. Instead, work on understanding the various concepts and theories. This will help you in solving more complex questions.
Hope this helps. All the best.
