I dont study Math but I do if there is a very long formula. Just think that the numbers are your friends and they are going to be good to you. I love numbers
you just have to realize that you can learn anything you want.
it's not possible for your brain to not being able to learn something as *easy* as some math exercises.
just be open and talk to people who understand it, then it's easier.
My tip is do a lot of exercises. Otherwise just pray.
This. Start long enough before an exam, re-do every exercise you did in class, ask someone to help you (I'm sure there is someone willing to help),etc.
