15-20 Days Preparation Tips of JEE Main:

  1. By this time the entire JEE Main 2020 syllabus must have been completed.
  2. Kick start with intense revision. Revise topics alternating with difficulty levels.
  3. Make short notes where you need refreshing or prodding so you can use them at the last minute for revision.
  4. Sit for regular tests to understand where you stand in terms of your preparation.
  5. 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.
  6. Lastly, keep your motivation levels high and don’t compare with anyone.
