Chances of getting into a dental school? 10 W's on transcript..

Well my first two years of college were a huge flop. I withdrew from most of my classes and failed the majority of the rest. At the end of those two years I ended up with a 1.6gpa. After my second year I decided to move home and make some personal changes, such as depression counseling, got back on ADD medication, and went through substance abuse counseling. Took a year off from school, worked at a hospital, and then went to school for a year at a community college to bring my gpa back up for readmission to a state university(OKstate). At the community college I took a total of 26 hours over the year and made straight A’s, reenrolled at OKstate and made straight A’s and 2 B’s in a chemical engineering/pre-health major. As of now I currently have 35 hours left to complete and am wondering if I should even pursue dental or medical school. Some thoughts? Should I continue to focus on dental or put my efforts towards a chemical engineering profession?
Some other background- During high school I accumulated 300 volunteer hours at a local hospital, and accumulated 100 at the same hospital during college. I’ve shadowed several dentists for probably around 60 hours total. At the state university I became involved in 2 pre-health clubs and a dentist club. Will these extracurricular activities help my chances at all?

Make an appointment with your pre-health advisor and ask their opinion.

Asking a pre-health advisor would be your best bet. Otherwise, I think you are not at a point of no return. You probably have to explain what happened, but the turnaround you made should help.

Keep in mind what med/dental schools want is someone who can succeed. if you have gotten all As in your last two years and you have done very well in all your pre-reqs, then you may have a chance. However, what is your overall GPA? You may find that there is a defacto cut off…I think DO schools want at least a 3.0. It also may have to do how well you do on the DCAT/MCAT
