Hey toothless...I had a 3.0 flat in biomedical engineering at a difficult engineering school where the average engineering gpa is ~2.6 or 2.7, so I def. wouldn't recommend applying with a gpa that low if your school's average is higher...my DAT's were above average except for biology but I have never had a conventional bio course so that was to be expected. My reading comp. was in the high 20s. I don't remember what my scores actually were because after the test I blocked it out (definitely did not get the 25 I wanted lol). I also didn't study at all for the DAT, I basically winged it. Some of my friends took a Kaplan course and did amazingly on the DAT.
I did a lot of extracurriculars, was a senior coxswain on the crew team, held various exec. positions in my sorority and school's engineering council, started some philanthropy programs within my sorority, and web design in my spare time (I think my interviewers thought I was the world's biggest nerd, but I like to think that I have varied interests).
I shadowed my general dentist over the summer, but not much. My family has a good number of dentists in it, though, so I've been around dentistry a lot.
My dad was also on the WVU admin committee a long time ago so we talked about what the adcom would probably ask, and he listened to my answers.
K, reader's digest version: you can definitely get in with a low gpa or a bit below average dat, but you need to stand out in some way, whether it be your grades/dats, extracurriculars, work experience, volunteering, etc. For WVU, they like it if you want to stay in WV, because why train you so you can leave and add to our state's brain drain?
Good luck!
