I will do neet so send me some tricks

You should refer to NCERT course books and focus on critical topics you have noted down or the one you typically overlook. For Biology subject, the candidates should completely focus on NCERT text book. Revise one chapter from NCERT's Biology book daily. For Physics and Chemistry, the student must clarify their concepts and keep the basics clear. A student can allot three week's time for the same and revise the concepts in the remaining days of the month by solving sample papers and taking mock tests. For Physics, the candidate should keep a formula sheet handy, for Chemistry, a sheet of equations should be ready, and for Biology, the candidate needs to prepare footnotes carrying important keywords. It is a must to download previous years' questions papers and observe how the questions were asked. This will help in understanding the distribution of marks among the subjects. Solve at least past five years' papers, which will give you a good idea about questions asked in the exam. Take mock test as much you can! It is the most important and useful way to judge your preparation. Time yourself when attempting each one.

From the last few years analysis, the most scoring topics of Biology are:
Cell Structure
Human Physiology
Ecology
