I do agree that DifEQ was the easiest of the 2 year calculus series (Calc 1/2/3 then DifEQ).
Yes you needed calculus first but it was far easier at the time of taking it than the 3 calculus classes.
Partial differential equations, advanced calculus, and real analysis however are a different ballgame.
Obviously it varies by university, but Calc 3 was super easy, too. Took me a while to get abstract algebra, but it ended up being one of my favorite courses.
Real Analysis was a real bitch. My proof for one question - which I frequently received a '0' for a grade (if it wasn't 100% correct, it was 100% wrong) - was often longer than the entire chapter on the topic. The book was absolutely worthless.
