- By this time the entire JEE Main 2020 syllabus must have been completed.
- Kick start with intense revision. Revise topics alternating with difficulty levels.
- Make short notes where you need refreshing or prodding so you can use them at the last minute for revision.
- Sit for regular tests to understand where you stand in terms of your preparation.
- Move to the next topic if you have done well in the first one else better and strengthen the first one before moving to the next one.
- Lastly, keep your motivation levels high and don’t compare with anyone.
