Discrete mathematics was a better "weed-out" class (N=1 so mileage may vary). Half our class dropped after spending half the semester on propositional calculus and truth tables. The rest got stuck on sets, counting, and big-O notation. I don't even know how it got that bad; we could even use a sheet for notes on the quizzes.

At least for me Discrete math was far easier than calculus. The hardest math class I took was the "statistics for science majors" class which was super application oriented and didn't justify half the things they did. Plus the textbook was this godawful online only thing that was super hard to read/search (and extremely poorly organized) and the online computer graded homework counted for half the grade (usually with math homework I just turn in the scratch paper for the practice problems I do to study it and get something around 50% but do very well on tests so that just didn't fit well at all with the way I study.)
