Fuck no to both. I'm prolly not the best judge of all this though... I dropped out of HS and got kicked out of three colleges, haha.
High school was absolutely miserable. Not much else to say on that. I pretty much knew that it wasn't for me by 7th grade.
College was pleasant and interesting in some respects, soul-crushing in others. I had some amazing profs and met some really cool people, and it was pretty nice when I just took whatever classes seemed interesting. But so much of the experience just left me depressed. When I was in the English program, the fact that I could write bullshit papers that said nothing of value and still get As from profs I legitimately knew were brilliant made me hate myself.
I switched from that first to comp sci, then physics, then math, but I could never will myself to make it through the first few semesters of mind-numbing 100-300 level classes. The way that most of these classes were taught was just awful. In all of them there were ~20% of us who "got" it, either through good intuition, self-study, or prior/outside knowledge. The classes were kept at a snail's pace and profs glossed over many important but complex ideas for the other ~80%, most of whom still didn't "get" it despite this. But the real problem was how these students were given information with zero context and told to memorize concepts without being taught the overarching ideas. I tried to make it through these classes while helping tutor some of the other students (very often all I needed to do to get them to understand the material completely was explain the logic behind what we were supposed to be memorizing.) But every time it just got to be too overwhelming sitting through classes that were far too slow and superficial to be bearable while knowing the majority of students would do poorly because the profs didn't understand they were being too superficial for everyone.
I could go one and on with the anecdotes, but yeah. I'm not trying to seem *~*~edgy*~*~ by saying this, but I just don't function well in rigid school environments I suppose.
