Thank you for the recommendations people.
I think I may be wanting to go for a hybrid or road bike. For those of you saying mountain bike, please give me some of your reasons/justification. Or you could list some specific pros/cons for each pertaining to my area.
To the person who gave me the route mapper, thank you! My ride seems to average around 4%, though some parts get up to 7 or 8% hills. Elevation seemed to range between 300-500ft.
(Where I live everywhere is gradual hills, though there are the occasional super steep ones. I checked one bad hill in the middle of my campus (I'll rarely ride that)...it was 20-21%)
I'm only riding on paved asphalt roads to class only (don't have time to do anything else than that because of school). I think I may want to purchase fenders...it's a temperate zone, we don't really have a rainy season, but it's typically raining all year. (Of course if not, the 300% humidity here will be sure to get you wet)
