I've had a batch of math classes, and so far, the most difficult IMO is differential equations. Lots of plug-and-chunk, and that's the problem for me: most of the time I don't know where to plug things.
If you've heard that Calc. II is the most difficult math course, it is likely because, as Justin Rising mentions, that is the last math class that most people take (some don't even go that far, stopping at College Algebra).
