I would look at each college's setting, in other words where they are located-the restaurants, the shops, the nearby services, as well as if their campus is spread out amongst non-college buildings or more self-contained. Every college has a unique personality and this is helpful when making your final selection. If you can visit and take a tour, many of which are student led, this will give you a lot of insight into the culture of each school, the student body, the clubs, and extracurricular offerings. Additionally, finance assistance may be a factor in your selection. Does one of the schools offer more in the way of tuition assistance than the other? Consider the living arrangements of each school; you will want to think about whether you would like to live on campus in a dorm or off, if you prefer to eat in a dining hall or prepare you own food alone or with roommates.
There is so much to learn and experience from your time spent at college that happens outside of the classroom, but that being said perhaps compare class sizes and the ease of getting the classes you need and want for a timely graduation.
This is a super exciting time. Best wishes!
