Do you know Richard Feynman?
He was a theoretical physicist, and he received a Nobel Prize for quantum electrodynamics.
He has a great skill called Feynman's Technique, for learning new knowledge, deepening what you know, or helping your exam.
Pick a topic what you want to study, after that, take a blank paper, write and speak on it in a simple language as if you are a teacher when teaching someone else. If there are some wordy or confusing, repeat the process from then beginning. Once you could explain it in a simple language and make a point, you have understood it and will remember it for a long time.
This method is very effective. You can apply it for your work and study, then improve effectively.
Wish you can make a big promote!
