Hello,

If you want to apply for JEE main 2021 then you have to concentrate on your time schedule of study. Physics, chemistry and mathematics are main subjects of JEE mains examination. So just prepared yourself one by one chapter. If you know that any one chapter is not prepared well by you then skip it but prepare others chapter very well. And do not answer the confusing question, if you are confirm about that answer only then mark it. Because negetive marking will be there.

All the best.
