hi,

I have mentioned some strategy which you may follow,

1 make a routine, and do study accordingly. give extra time for subjects in which you are weak.

2. always makes short notes on any physics or chemistry chapter you finished. these will be help full  at the time of entrance test.

3. make sure you have basic concepts clear.

4. daily practice numerical question from any good books, as jee main has all numerical questions asked in exam, rather than theoretical type.

5. follow arihant or tata macgraw books for mcq practice,  which is best for jee main.

hope it would help.
