I'd get an parkzone ember RTF. See if your college or local rec center will let you fly it in the gym? If you really like it you can step up to other micros, like the T-28 (I'd also probably invest in a real radio, like a DX6i as well). Once you ahve a good radio, then a ton more options open up for you for super small park flyers.

Not sure where you're going to school, but when I was in school, there were large enough buildings that would block out most of the wind from a given direction so I could pretty much always find a calm place to fly around here. So I wouldn't necessarily get scared of the micros if you could find such a place. Honestly, if you're living in a dorm, having a big 60" nitro trainer with all the equipment won't be much fun. The micros are good b/c if you get the parkzone ones, you can use the box they came in for safe storage and stash them under your bed or in the top of a closet or whatever.
