How should I self-study calculus? So I already took Pre-Calc, and ended up with a B both semesters. I am an incoming senior in high school. My special-ed case manager won't let me take it because she doesn't want to see me panic (crazy, right?). But, for some reason, I really like math. Is there a way for me to self-teach myself Calculus I or Calc I and II before taking it at college? I already have Humongus book of Calculus Problems and PatrickJMT on YouTube (My favorite math youtube channel). 

There are many ways you can learn calculus. There are many textbooks out there dedicated to calculus, such as Thomas' Calculus, Stewart Calculus, Spivak Caclulus (more rigorous than the other two and is meant as an introduction to real analysis), high school calculus books, etc.
There is a professor called Paul and he has a lot of good notes on algebra, calculus I, II and III and differential equations on his website. Go on the 'Class Notes' tab and choose the course you want.
If you like video lectures, then I think the best courses are MIT OCW single variable calculus and multivariable calculus courses, which you can find here.
