I'm only in my first real and I still have to take LOTS of math, but my experience so far:
HS Calc, Calc 1 & 2: easy. I haven't been to calc2 lectures at all this semester and I'm getting 79%.
Linear Algebra - I actually found it easy and quite interesting. Vector spaces, inner products etc all made a lot of sense. Nice course
Regular algebra - HS course in algebra was very easy and enjoyable.
Trig - identities are a pain to memorize, but its alright...
Geometry - I liked it, but didn't love it. It was ok.
Arithmetic - you're joking, right?
Discrete - I took an "intro to discreete" in HS - stuff like factorials, probability and such. I hated the material, so I didn't do as well as in Calc and Algebra. Gotta take a discrete math course in 3rd year, so we'll see how that goes...
