Spaced repetition, make your brain store information
A simple way to do spaced repetition is to use flashcards organised into a box. Set up a schedule for when you will revise the cards in each of the sections in your box. If you answer a card correctly, you put it into a section that you will revisit less frequently in the future, whereas if you get the answer wrong, you move the card into a section scheduled for frequent visits.
