How do I remember all the formulas I will need for questions.

It is difficult to remember formulas, especially when they are similar and easy to confuse. Some methods of remembering the many formulas needed for physics and maths are to recite them, to do a lot of practice questions with them while trying not to look at a formula sheet or even to write them down and stick them on the walls around the house. This will mean you will read them daily and can make a difference in helping to remember them.
