Many moons ago, when I took organic chemistry, I did well with the course classroom work, but, the pace of the lab work was brutal. Well, a hefty load of engineering classes didn’t help. And, the teacher was an arrogant a-hole. I caught an error on one of his exams and then he wouldn’t own up to it. Even though he’d warned us to be on the lookout for little “gotcha” stuff like that, that he might throw in to cross us up. Nor was I impressed with this guy - the TA got material across better, as did the teacher of another section who allowed me to sit in on his class a couple times.
The lab bothered me more, though. 12 lab reports were expected; to pass you had to get an “A” on at least 10, or average “C’s” on all 12 I think(?). Students were literally running through the lab room to try to get all 12 in, and some of the stuff we were handling was downright dangerous. Mind you this was 45+ years ago, so, we weren’t a bunch of distracted-by-smart-phones students. And, I really liked chemistry. I refused to work that “frantic”, and managed to get 10 labs in. I passed, but wished I’d been in that other section...
OTOH, when I took Technical Writing, that teacher was a retired Army writer (never did find out EXACTLY what he wrote). The dude really made us work - not on the level of an engineering class, but way more than a typical General Studies class. (This was a 300 level class, required in Engineering & most any other “tech” oriented field, IIRC.) My God, how did the students from Ag and so on bitch and moan... They started talking to their friends in other sections and found out we were literally doing 3x the work. Then they really howled! I didn’t mind - my aptitude was good and I was learning a lot. The instructor corrected the textbook several times, and every time it turned out he was right. Probably was the only GS class I was actually proud of Acing. And, it likely helped me on those Organic Chemistry lab reports. :)
These days, in informal settings I often fall into “Manny-speak” writing. (Heinlein) Ah, well...
I always thought that organic I & II were the roughest courses that I had to take. They ended up becoming my “one – up” on my son.
My son, before he received his EE and Biomed Eng degrees, was thinking about applying to med school, so he took organic, dropped it, took it again, dropped it, before finally passing it (he decided to become a lawyer after that – which he did).
