Please don't think that it's impossible to get into medical school with a 23 on the MCAT. Yeah, it's certainly not going to win any awards, but all hope is not lost either.
Here's the proof:
My MCAT (10-VR, 6-PS, 7-BS, S-WS) 23S
Accepted to 3 DO schools (touro, western, and lecom)
waitlisted at UTMB (MD school in TX)
GPA 3.5
Know, obviously, I wasn't going to get into friggin' Harvard or Hopkins or anything, but I'm still going to be a physician, which is what really counts at the end of the day.
So, retake if you want to retake, but do consider applying. You're certainly not going to get in if you never apply.
Good Luck
