I know people will say that I'm a nerd or whatever. I got 92 on my finals. Just focus in class and learn it every day ±1 hour. You will be able to get better grades and if you keep doing this your grades will just go up. Exception: If you never focussed in class or did not study, you will not know your basic math. Good luck!

Its oki, I failed all my math tests so far. Good luck mate, ask your teacher to show you stuff when he or she has time, because it really really does help.
