Firstly starting with biology focus completely on NCERT read it regularly don't leave even a single topic cover it entirely . Because maximum paper is based on NCERT  so read it with all your effort. Than solve modules of different coachings try to solve different different question so you can cover your entire syllabus not only questions from particular chapter or from your favourite topic. 

Everyone says biology me marks nahi aate its because people doesn't study it the way they should study it everyone solves different modules and different books but they never focus on NCERT so its very important to focus on NCERT rather than any other book.

Than in botany there are certain numerical type of question solve them as much as you can . In zoology try to cover entire animal kingdom but cover it slowly don't try to get everything at once because that chapter is soo big , so focus on everything but get frustrated by doing everything at once. Divide your time and decide subjects according to  the time .

Now chemistry everyone gets problem solving chemistry specially in organic chemistry , the reactions and everything but its not as difficult as we think , as in biology start chemistry also from NCERT text book , understand everything slowly and practice as much as you can ,get as much doubts as you can because if you studyimg and you are not getting any doubts then you are not studying properly. 

Solve as much as modules you can solve discuss questions with your friends it will increase your confidence and at last it will definitely help you im your preparation . 

Everyone says neet is difficult ,but its not like that people doesn't study as should be studied , everyone had lots of doubt but they never as   so study smartly and with sharp mind ,without having any tension or stress.
