What to expect in a high school?

Currently a senior in high school. Honestly, it depends on your intelligence, how social you are, and where you go for how well it goes. If you're too smart at a school where the majority is less intelligent, you may be shunned as a sort of nerd. If you are social, know who and who not to hang around. If you go to a school with a "bad" pool of students to pick from, it may not be the best experience. Just try not to stick out too much, unless it's for something "cool" like football or something that the hivemind accepts as a good thing. If you stick out as a nerd of sorts, it could get bad. Best I can say is be yourself, but know if you've gone too far and as mentioned before: don't judge right away are place yourself above someone.

Personally, I attend http://en.wikipedia.org/wiki/Baton_Rouge_Magnet_High_School, where most of these statements do not apply. In my 3 years here, there has not been one major fight I have heard of, students accept you regardless (until you're an ass to everyone and just piss everyone off), and being a nerd is encouraged due to the school's position in terms of state/national academics and academics required to attend.
