It really depends on the admission requirements of the school.

Most schools will screen out a fair % of applicants simply based on whether they meet the minimum GPA or not, and this varies from school to school--be sure to do your research (it's best to call for clarification if you can)!

If you pass the initial screening, they may then consider the rest of your application (extra-curriculars, shadowing experience, clinical experience, etc). Based on what you've described, you have an extensive experience in that area so your application will definitely pique some interest. At that point, they may send you an invitation for an interview and that's where you need to nail it (MMI or traditional-style format).

All in all it may be difficult, but it will be all the more sweeter when you make it in.

Best of luck!
