You would not like to derive any of those formulas in your exam. Memorize them somehow, that would be best for you. Else you will just keep deriving these formulas in the exam and not solve any questions.
To memorize them, write them all on a chart paper and paste in your room or above your study table, where you will be able to see them daily. Also, you should practice a lot of questions. The more you practice, the more is the chance that you will remember them.
