Important Tips for Preparation of NEET/IIT-JEE
- Select a good mentor for all the subjects. Several educational channels and the best mentors of Physics, Chemistry, and Biology are available on YouTube for free. You may follow one of them for all the subjects rather than wandering here and there.
- Centralize your study to the NCERT books and one reference book each for Physics, Chemistry, and Biology. Don’t follow too many books otherwise, you would not be able to complete your syllabus. Always remember, different books differ being only nineteen or twenty in text quality, but never differ of being nineteen and twenty-five.
- Follow quality notes of a good mentor for all the subjects. Don’t run behind the brand, but run behind the concise and effective notes of your mentor.

- Always be confident in your preparation but never be overconfident. Always read the question carefully and then answer. You usually make mistakes in overconfidence and it has to be reduced.
