I was in your boat. I applied this year, late too as in October.
I had 4 interviews with a MCAT score of: 6V, 12P, 11B, W:R
And being an Asiam Am from Cali didn't help either 😀
It was NOT easy and I had so many rejections that every time I count the number of schools I applied to, I lose track of the number.
However, I did get into a US Allopathic school. I posted a thread on the Pre-MD about how I didnt want to go to the school based on location. At one point, I was even contemplating giving it up to go to the carribeans, where the last two clinical years are in NY. (I know it sounds dumb).
I'd say you are in a sticky situation but I don't think you really need to hit a 13 on bio again. I think even if you get a 8 on V, and 11 on your sciences, you should be in good running. And I do agree, lopsided MCAT really does hurt your chances.
I'm still waiting to hear back from one last school though, which is my top choice.
Moral of the story-- It can be done, but it will be an uphill battle. I was so stressed the entire year. I'd rather retake, have a good MCAT, and go to interviews relaxed, knowing that there are no holes in my numbers because I was asked at EVERY SINGLE interview why my verbal score was so low.
