Mandarin Abandoned it after a semester. Still sticking with Japanese & Korean and they're hard too. The other history/politics classes I take are a cakewalk in comparison.
the material isn't hard but there's so much of it that I'd spend hours upon hours each week preparing for tests
Memorizing muscle names, locations, their insertion and origins, what type of motion they contributed to, and what type of lever systems they are -- in addition to spelling them all correctly -- in the span of a few weeks nearly sent me over the edge
My professor was known for asking tons of trick questions on exams. I'd be taking his tests and cursing at him in my head the entire time
This! My professor was so bad he was reassigned after his first semester teaching it because his reviews were awful.
I took Geometry in 9th grade, and that was a pain in the ass. First time I hated math. I'm currently taking a U.S. History course in college. There's a lot to take in and memorize, and if I don't come up with a great study technique, things are going to start to fall apart as the semester progresses
Cell Biology. My professor acts as if we don't have any other classes or responsibilities.. I probably have spent 4 to 5 times more time on that class than Organic Chemistry and Mammalogy combined (my 2 other classes) just to keep up with the demands.
