I just started physics at uni, I'm at the third day, I dont know calculus very well because I didn't study in high school, I am already self studying math to make up for my lack of knowledge but in the meantime uni already started so I'm considering dropping out and restart the next year after I have a more solid base, maybe that retarded and I should just study more in the beginning and then I'll be ok, I have to study limits derivatives and integrals
