I'm doing my first semester of physics and i dont know calculus and did math like shit in HS so i'm re studying math from the beginning on khan academy, i almost finished algebra now and will move to pre calculus in some days then calculus.

I have 2 months to prepare for a calculus 1, machanics,programming and statistics exams.

Maybe it's stupid to wait to start calculus and mechanics until i've finished restudying math like i'm doing but i want to do things in order, anyway if i study 6/8 hours a day i should make it, im doing 5 hours a day right now.
