Get ready for a megapost with me responding to what a lot of people have said!
Showing concern and dedication will get you everywhere.
This. So much this.
Guys, I'm going into my final year, and I'm so fucking excited / so really intimidated by the fact that I have to face real world soon.
Two words: graduate school.
(and trust me, they really deserve more pity than you realize)
I'm going to make you crazy jealous, and you'll probably never talk to me again. I am currently one of three TAs for a class of about 20. BAHAHAHAHAHA!
Also, I'll be doing full time uni and close enough to full time employment, all at once. Crazy? Probably.
My third and fourth year of school were completed while working pretty much full-time as a musician. Luckily, a lot of the practicing overlapped with my music degree. Once you get a schedule going, it's actually not too bad, and you're never bored.
(What I am saying is that I have an insane amount of work and the idea of doing anything except occasionally sleeping and working and school is really foreign already)
You will find that there is time to be social (not necessarily drink, mind). It won't be there at first, but you'll slowly get your schedule down to where you have free time.
Yeah seriously dude are you actually suggesting that it is unfair or ineffective to have lectures that go for less than an hour what the hell is wrong with you people.
Unfair to have
required lectures. My dad got mostly top marks in his undergrad degree rarely setting foot in a classroom. Some people just don't do well in a classroom situation.
Is there a place for History majors in the world, if I am not working at a museum? Should I be a teacher?
Yes. What level would you be hoping to teach? Because University/College level is insanely competitive for humanities people, but high school is probably much better.
Do not let anyone tell you that you need to drink or have a good time or basically do anything apart from study at college, you will know if you have spare time to do this stuff by about the end of the first week.
College is also a place to grow as a person, as well. So try to at least be sociable, and always keep in mind that "sociable" doesn't mean "alcoholic." It doesn't even mean there's alcohol involved at all. I'll temper this with, if you don't feel you can get your work done, do your work. People will either understand, or become drop-outs very quickly.
Also do not be afraid to get to know people in your classes on the very first day you have them because otherwise you will not talk to them all semester and it will be even more awkward if you have another class with them later and try to introduce yourself then.
You will also probably not survive without some sort of support group of friends. As awesome as college is, there is a lot of stress and sometimes it just gets too much.
To be fair note that art classes are often longer, because you're in the studio doing the work, rather than just listening to a lecture and doing all the work at home.
So, it's like mandatory "homework" time? Damn. I mean, I had rehearsals, but individual practice was to be done on my own time (once, my teacher was really pissed off that I hadn't put in enough work that week and just left, saying that I could practice if I wanted to, but he saw no reason to remain around).
