It is very difficult to crack JEE Advanced in one month. You can crack it if your concepts are clear.

You must follow a strict time-table if you want to crack it.

Forget staying up late at night and instead wake up early, at 5:30 A.M. A fresh mind is a better receptor and they can start their routine early on in the day. Design a fixed time table for this month too and try to form a habit of studying for at least five to six hours at a stretch. Students should focus on practicing more question papers in the morning. After evaluation of every question paper one can easily decide which are the chapters they should focus on. So the rest of the day they can revise those chapters.

You should complete your NCERT book. Solve previous year papers. Devote your time to important chapters.

All the Best!!
