My best study tip to strengthen your memory and crush your exams

Study for 20-30 minutes, (that's about what your brain can handle before its not absorbing any more)

Grab a blank sheet of paper. Recall from memory what you can. Paraphrase it and write it down. Then check what you missed.

This method forces you to actively recall and process information. It tell your brain its important and to remember it.

It causes you to encode the information so it can be understood and stored in memory.

Do this and information will just stick and you will just get it. Your gonna be able to recall it quickly, understand it deeply, and retain it long term.
