Not too easy. Not too difficult.
If you are a freshman, you are randomly assigned one of many dorms across Central or North Campus (You cannot request a specific dorm unless you are in a learning community). They vary greatly and each has their own advantages and disadvantages.
The nicest dorms are West Quad and East Quad. South Quad has large rooms but they are fairly old. Couzens and Alice Lloyd are also very nice but hard to get. Mojo is decent. Markley is very old and somewhat dirty but it is all freshmen and the most social dorm so you are guaranteed to meet friends there.

Advice for students:
The general consensus is that you want to be on Central campus and not North because you have to take buses back and forth from North to Central where most, if not al, of your classes will be. It can be extremely inconvenient but it is much quieter than Central and you bond with those on North as well.
