Hello,

For JEE MAINS it is very much important to clear the total syllabus of Class 11 and 12. Basically in jee mains question pattern the board syllabus is cover up as a cbse pattern. But beside this you have to finish sharpely your calculus part, organic part and 3 d mlotion part.

Hope it will be helpful for you.

Thank you.
