this may be vague, but dont be scared and dont procrastinate. think about where will u be after some years if you r not doing what you are supposed to do and think where you will be if you do!! there are so many revision techniques and not everything will work for you but try some methods anf find out which will work for you. flashcards, blurting on a white board, making equation cards watching videos and PRACTISINGGGG!!! good luck !
