Overall, I love Creighton. It is a really great place to go to school. However, I would change our dining service. The food is subpar, the hours are not great, and the service is weak. The size has been perfect. My largest class size has been 60 (Calculus 1) but other than that, all of my classes have been less than 30 people, and most are actually closer to 20 (I am in the Journalism, Media, and Computing Department though which is a little smaller, so your Biology and Chemistry classes might be a little bit bigger).
Not everyone shares my feelings of Omaha, but I have really loved it as a college town. I come from a huge city (Phoenix) so I was a little tired of all the driving and traffic, and Omaha has been the perfect escape. It's still a big city (almost half a million residents according to the 2010 census), but its small enough that I don't need to constantly battle traffic, or take the freeway to get anywhere. There is plenty to do in my opinion. The Old Market is about a 15-20 minute walk (3 minute drive) from campus into the downtown Omaha area and it is a ton of fun. They have all sorts of restaurants, coffee shops, ice-cream, and a bunch of other little shops down there and its a very fun walk. At night they run horse-drawn carriage rides through the market too which is fun. There are some cool parks on the Missouri River over that way too, and a pedestrian bridge which crosses over to Iowa, and is really pretty at night. There are also bars and clubs and what not for the upperclassmen too. So there are things to do here!
We don't have a football team, so its hard to have a whole lot of school pride during football season, but we have a very good soccer and basketball team, both of which are a TON of fun to watch! I would definitely recommend going to both. I was never a soccer fan, but after watching a Creighton soccer game I was hooked. Not many schools can say they have a good soccer team so thats pretty cool. Plus, as a Creighton student, you get to go to every home sporting event we have for free! So they make it easy to enjoy the sports here.
The weight room is not the greatest facility you have ever seen, but it is definitely passable, and the only things you would ever need to wait to use are the treadmills and ellipticals. I try to get to the gym once a day, and it is a fine facility right in the middle of campus, and it has just everything I need to get a good balanced workout. In addition, we do have a second gym down in the Harper center that is newer and much nicer (though a little smaller from what I understand because I haven't used it yet) and Creighton is currently contracting a new athletic building down by the soccer field, so we should be seeing further improvements on that front in the next year.
Like I said at the start, Creighton has its weak points like every other school which can be frustrating, but overall I really love going to Creighton.
