I think many folks score a few points below their practice average (I did anyway). I'm sure there are other anecdotal experiences that differ. If I was in your position I'd take it again when my averages had increased about 3 points higher than before, to have confidence that I've improved. In any event, I hear about folks who get in with your stats, especially DO, so it doesn't hurt to apply now. Just be realistic about your school selections. Best wishes.
