hi,

see since jee main is an mcq based exam it is quite difficult to predict the suggestion for any of the subject. however since exam is very near so it would be best to revise the old lessons and practice ample number of mock test. at this time if you tried to learn any more of new chapters it may result to forget the previous lesson.

so just revise the subjects which you have vast knowledge and give mock exam. follow the below link to give jee free mock test:
