Hello GARVIT,



You need not to cover full chapter of both chemistry and physics , that would be a hard way at this short time and if you still able to cover all syllabus you might not get time to review and revise whole of the syllabus and without revision nobody can recall formulas or pattern to solve numericals.

So I would suggest you to look at the previous year questions papers  ( GRB publications is good for these papers ) and check each chapters important sections from where most of the questions are asked then practice those concepts wisely.



Try to solve MCQs as much as you can cause even if you know concept and formulas you can face problems in exams if you haven't already solve and seen those type of questions .



Another way is that since you are studying 12th syllabus  now so you continue to cover these chapters  only but as per NEET not as  boards and after your boards you can solve important topics of 11th call too.



But for biology you can't skip even a single page of both NCERTs.



If there are still any doubts let me know in comments.

Good luck.

Thanks
