A few points are most important and will retain your memory for a long time. I hope you understand what is taught in your coaching classes so after that-

  1. Go through your class notes once, then try the same type of question in a different way to increase its difficulty
  2. Start using reference books after you have gone through your class notes.
  3. Start solving problems from the basic level to advance .
  4. Start making short notes but not the same thing written in class notes. Add those questions concepts that you are not able to solve. An extra point you want to add that's written in the book. Any shortcut/formula you discover by solving so many questions.
  5. In difficult questions, try to reframe the question again. This will increase your thinking process and concentration and you will start loving the subject more.

All the best 👍👍👍.
