Hello, I am currently in high school and want to persue a career in dentistry. And my grades are OK......A's,B's, and C's. I need to get rid of the C's. But I wanted to know if I could do more, like volunteer to make up for my usleless grades? What orginazations are there concerning dentistry? Does volunteering/ extra-curricular count for anything when you apply to a dental school after you've already done pre-reqs at college? Thanks.
