There was a webinar a while back and from what I can remember I think the average GPA from the last cohort was like 3.6 and from the one before 3.59-3.78. These are the two sets I have written down on my notepad. I was also rushing to write things down so those may belong to a different cohort or something. As for acceptance, I know the cohorts are around 70-75 so they must accept a little more. I have heard that with the interview gone they really focus on your personal essay, letters, and of course grades from pre-reqs.
I majored in Psychology with a good GPA, not outstanding but not bad. I graduated a year ago and have been working job and going back to school to complete most of the pre-reqs.
Now I'm just waiting for the application to open! The admissions counselor said they would open the one for fall 2016 mid august so I'm kind of waiting until then!
