Good luck to @Kenshin_sama and @Barktooth! College may be intimidating at first but it'll become a routine eventually so i'm sure you guys will be fine. Depending on your college, they may have genshiken sort of clubs, so you may just meet a bunch of people that'll end up liking the same things and having activities like viewing parties and stuff along with it.
If you'll are soloist, don't worry, just keep up with your work and start assignments bit by bit as soon as you get them and you'll have plenty of time for animes, vns etc. Try not to procrastinate!! [if you want your anime time that is]
Doing last minute assignments is a huge F-ing pain [i did a few of them last minute 2 in my time]. Again, good luck! and have fun!
