I'm a Junior in Computer Engineering and will probably graduate with a 2.5 GPA if I'm lucky. Do I have to start my college career over with a major in Biology and a GPA over 3.5 to have a chance? Is there a "post-bac" program for aspiring dental students like there is for medical? If so, is it enough for a 2.5 student like myself to have a shot at getting into a dental school? What should I do?
