I had a 3.6 gpa, 19 overall, 16 pat, and 16 organic (after taking only 1 semester), 21 bio, 21 reading, 18 math and chem. I had 120 hours after 3 years. And got into Indiana, Penn, and Minesotta, I had about 10 other interviews in Feb, but canceled them all. I shadowed a dentist for 50 hours and worked at a dental lab over the summer twice a week. I also had a lot of extracurriculars. I say go for it and pm me if you have any other questions.
