Is it possible to teach myself calculus? I'm 23 years old and I decided to be a fucking layabout in college by choosing to major in meme humanities subjects. Last real Math class I took was a non AP Calc AB class, which I only got B+s in even after seeing a tutor for a couple of months. Should I enroll in community college to learn it or could I just pick up a text book and use khan academy/youtube videos?
