I agree with above regarding Umass, SUNY May be okay.
You’re not going to be one of those people if you can have a normal conversation and aren’t a sociopath/raging a-hole.
You shouldn’t have retaken that 512 and you are very lucky it was a significant improvement rather than a decline, which I say more for others who may read this thread. 3.8 with 508+ has an excellent shot and does not need any intervention in MCAT or GPA.
You’re on the right track, you’ll get interviews at several places and accepted somewhere. It’s going to be okay, take a breath and don’t let the anxiety consume you.
Good luck to you!
