What do I do in the last 3 months of JEE preparation to get a good rank?
You can take guidance from IIT JEE mentors. They will help you to improve your study plan and suggest to you what things you should include in your preparation and what things you should avoid. To be perfect at any subject you need lots of practice. More practice will get you the ability to solve tough questions in less time . Practice will improve your analytical and problem solving skills. So practice more, give mock tests as much as possible. After attempting one mock test first analyse your answers. Try to recall related information. If you can not attempt any question or give wrong answers then pay more attention to these questions and revise them frequently. Be confident, and never get nervous to see a long question. They might seem difficult but with practice you will be able to solve these questions in a few minutes.
