1. UW has a very strong balance between their research and clinical emphasis. They receive a ton of funding for research, but they also consistently rank in the top for the National Boards II (they were ranked #1 last year as was stated earlier). Here's a good article about that:

2. I would say it is very tough to get admitted. In my opinion, numbers are very important to them, i.e. gpa, DAT scores, etc. But that will only get you in the door. They care about everything else as well. They are really seeking well-rounded individuals.
3. The small class size (55) is very appealing. The location of the dental school within the Health Sciences Building is less than desireable, but the clinics are very nice and well lit as well as many of the other rooms.
If you plan on specializing, it's a great school to go to. Almost everyone who applies to a specialty from UW gets accepted, and often to their #1 choice.
The faculty, administrators, and staff that I've met are very nice and helpful.
If you're looking for an easy school, do not go to UW!!! I have heard it is intense. They are actually working on making it a little more manageable. This year they are going to start anatomy 4 weeks earlier than the rest of the courses. So for 4 weeks you can focus solely on anatomy and not worry about the other classes. You can also test out of several of the 1st-year science courses at UW if you want.
