Even if this goon managed to raise his quantitative score to the 55-60% range for next year's application cycle, he's still not likely to get in. Why? Because he already mentioned he has no healthcare experience. If all he improves his application with is a higher GRE score -- and I doubt he has the motivation to do anything more than that -- he definitely won't get in. If I was on the admissions committee at a program and was handed his application to review (this might not be entirely hypothetical... hint, hint), the first question to pop into my mind would be, "What has he actually been DOING over the last year?"
I don't want someone going to my program who has the nerve to spend an entire year doing nothing but going with the flow. Sure, he might re-apply with a higher GRE score, but unless he gets some healthcare experience involving at least a modicum patient care (and it is very hard to get this experience without a certification or some other form of qualification), his pathetic ass is going to be stuck at home at mommy and daddy's house (I'm assuming) for another year.
