I was recently accepted to the university of Alabama and umass Amherst. I’m devatiing which I want to go to for chemistry. I will be paying around the same amount per semester and I live in Connecticut. I want to have fun but I also take pride in my work. Please help me !!
Well UMass is quite boring/quiet in the North and east dorm areas of campus as well the honors dorm in the south. (Virtually not parties) Perhaps the central dorm area would be best for you? It seems to be the have fun/still care about class kinda place. To be honest I don’t know what you heard… but UMass Amherst has quieted down a lot more in past years. I would look to Southwest if you want to see the most active part of campus. (Party wise and people wise) Personally I prefer the North of Campus. 
PS - I would also think about plane tickets prices since Alabama is quite far from CT.
University of Alabama’s social life is heavily influenced by Greek life, if you’re into that sort of thing you should go there otherwise I would choose UMass. As Greenman said, keep in mind that plane tickets are not cheap.
