What I've seen is that if you just don't get it, it's 10x as hard than if you just haven't memorized it. I usually got the math. That's why I hated Bio, and didn't care too much for orgo. With higher math, I've had open-book, open-note, asking the teacher for definitions, and all kinds of other stuff that would never ever ever fly in a bio class. I can just imagine the bio prof's eyes bugging out if I asked him for a definition. Never saw a multiple choice math course even in HS. Computational math is a cross between the two, as you can always do fine as long as you do problems over and over.
I avoided engineering courses though b/c of the profs' attitudes. I don't know why, but all engineering profs seemed to be jerks hell-bent on seriosly weeding out everbody in their 15-person class. wtf? I guess the risks are higher for engineers that for "pure guys." A bad bridge has more consequences that a bad theory...lol
I better start liking memorizing for med school. You too 😴
