As far as going through with the admissions process, I think that unless you had prepared for this sort of scenario you might want to change what you are doing. I think it is possible to get in with these numbers because you have good grades, ec's, letters of rec BUT it would involve applying to all your state schools and as many lower tier schools as possible. If you applied to enough schools, you may stand a chance to overcome that low mcat. As someone mentioned, DO schools do have mcat averages a few points lower so that might be a good option.
But if you are talking about just applying to 10 schools or so, I do not know if it would be enought to get you in.
I would say go ahead and try this year if you are already in the midst of the admissions process but plan on retaking the mcat.
If you still do not score well, save up some money and apply to a ridiculous and obscene number of MD schools next year or try DO schools if that is what you want to do.
