Hey Nitish.

See it is quite difficult for u to get a score above 200 if u don't have command in even 6 chapters only in the syllabus of JEE MAINS. U should be solving unsolved papers more and more and try to revise the formula book for the best output in the JEE MAINS exam.

See getting a safe score doesn't need too much hard work just make a plan of the heavily marked topics to get some scope.

Hope u got ur point. Ask if any other query.

Good luck
