Should I skip math class?

I have been skipping english class the past two days. I think I could get by skipping math. What the hell do you people think?

"Fucked, because mathematics is made of very obscure knowledge only your teacher has access to, which you can't possibly find anywhere outside of that one class? Study on your own, faggot."

Yeah, and the teacher writes the fucking proofs.  In the syllabus it said, "Use of a textbook is not allowed in this course.  It won't do you any good anyway."  These are insanely difficult proofs, based on the concept of real numbers as the equivalence classes of Cauchy sequences of rational numbers.  Hell, I tried looking some up online once, because I thought it would save time, and the proofs I found were based on different axioms.

In other words, it was Advanced Cal (as in, advanced *college* calculus, not AP), not Geometry, fuck off.
