Hello student,

Actually see you must should know that the syllabus of both state board and joint entrance examination is quite same if you are following your NCERT books. Yes office there are some extra concepts needed for JEE main examination but you can do that in your coaching also. My advice is that you should make a routine of your daily life to use your total day in a proper way. Divide your time for your JEE main preparation and and divide your time for state board preparation. You can go through lots of mock test to know the question pattern office you have to go through previous year papers as well. You also can take a drop after completing your state board to prepare well for examination.

You can have a jee main knockout course which has lots of good video lectures, lots of mock test, personalized reports and timetables.
