I was accepted EDP this year. From what I know, I would not apply EDP if you are below a 28 MCAT and 3.5. EDP is supposedly harder than regular decision. It's hard to get an interview in EDP, but if you do, then your chances are very high for an acceptance. In RD, they hand out interviews to everyone.
I know 2 years ago, the #s for EDP were: 140 applied, 70 invited to interview, and 43 accepted. The rest were pushed back to RD. For this year, UTKD actually knows the #s. At the EDP interview they told us that the previous year they only accepted ~60% of EDP interviewees and wanted to boost that for our year. In past years, they said they accepted 90%+ of EDP interviewees. The reason they only accepted ~60% (43/70) 2 years ago was because they handed out interviews based on numbers and didn't read the applications much until the interviews. At that point, they said they were left with a bunch of ppl they felt had nothing beyond numbers, so they only accepted 60%. So, for my year (this year), they were much stricter on giving out interviews. They said they read each EDP application in detail. So, they looked at your #s but also heavily looked into your volunteering, clinical experience, recs, etc. I think they said they interviewed 60 EDPers this year. No idea how many got in but I would expect it to be closer to that 90% than 60% due to the changes in EDP admissions.
If you want a good recommendation on if you should apply EDP, then contact Sally Mccurdy and ask her.
with your application!
Good luck! I am hoping that I can get a decent MCAT score this Thurs, and I also hope my limited volunteer experience doesn't hurt me. I'd much rather be rejected from that than a low MCAT tho. It's not as expensive to volunteer.
