Most Difficult Math Class?

I'm a freshman in college right now, and I'm getting ready to take my Calculus II final here later this week.  I've always been very good at math, but this last semester was by far the most difficult math I've ever taken.  For the first time in my life, I'm actually having to study outside of class, and I'm not certain of at least a high B on this test.

From talking to some of my sophomore buddies and a few of the teachers I'm on good terms with I've heard that Calc II is about the hardest math I will ever take.  Would you guys agree? If not, what was the most difficult math for you?

calculus is hardly even math, it's just arithmetic.  everyone hates calculus because its so dry and boring, not because it's hard.
