I'd guess from here:

Doctor of Osteopathic Medicine (DO) Program Data | PCOM Georgia
Doing the math from # accepted vs. # matriculated

That doesn't really give a chance of getting off of waitlist.

But from certain source, you can kinda find how many people getting interview or other campus like PCOM South just post how many they interview.

Interview candidates × 0.85 (assuming 15% people getting rejected)

Gives either waitlisted or acceptance.

If 367 people are given acceptance with 135 class size, and waitlist only rendered out after class is full, then we can guess

367-135 which is 232 people who had at least had gotten off from waitlist

232/ total waitlisted gives the statistical value for the chance.

For PCOM South, it is roughly 280 interviews for 59 seats, with 165 acceptances.

So maximum 106 people were pulled from waitlist.

0.85 × 280 is 238.

Therefore, it is 106/238 which is 44%.

Considering pcom ga will follow similar trend for its school's mission and average stats of candidates, I would expect it will be similar to South or even worse since it's more popular.

But this is not anything reliable to believe the actual chance.

It just tells objectively that at least this amount of people don't get in even after getting waitlisted.

However, there can be case where acceptance offer are made a lot in early cycle where people turn down the acceptances where it leads acceptance made on a following interviewed applicants who gets acceptance right away rather than getting waitlisted which will lower the maximum waitlisted people getting pulled.

Therefore, it matters a lot when you get waitlisted, and their is a significantly different chance for people getting off from it depending on when the decision was made. Because cumulative acceptances which will lead to matriculation builds quicker as the cycle gets closer to end. So there is huge difference in significance of difference between getting December vs Jan waitlisted compare to Jan vs Feb.

There might be only a month apart, but chance of getting off of waitlisted will be much lower as it gets to late cycle since it is exponential.

But again, I believe school will build class profile to their mission where everyone hold different values and priority. But it is safe to assume maximum chance of getting off of waitlist is no more than 44%
