Let's see, for all the schools I've been to, the feeling was:
Pre-K: I'm assuming that I liked it, but can't really remember, seeing as I was four.
Kindergarten - 3rd: Again, assuming I enjoyed it for the most part.
3rd - 4th: Wasn't too happy, seeing as I had to move into a area that I didn't want to live in with people I hated. Also, it was probably around this time i started becoming psycho and very aggressive.
5th: Hated it. Wasn't even really in the school at this point, seeing as my entire grade was crammed into a "mini-school" (a trailer w/ no windows)
6th - 7th: Hated it. At least half of the teachers either didn't teach/spoke english/have a room, and the place closely resembled a prison. (looks even more so since they cut down the two trees they had.). Your classes didn't stay the same for long, seeing as they changed every month or so. The building wasn't heated or AC'd and you often only had a minute to go from the first floor to the fourth on the one and only stairway the school let the students use.
8th - now: Enjoyable enough, despite the fact the school doesn't have windows. Teachers are nice enough though.
