<p>If you retake, you better have A/ A+ since both will be counted, you cannot get rid of your previous grade (as far as I heard, no personla experience). Then if you pull a decent MCAT, you may have a shot.<br>
One thing I do not get. Why do you think that you will pull an A, when you could not do it before? And if you could, what prevented you from getting an A? Unless you have a clear answer, I cannot see why all of a sudden you would get an A instead of C.</p>
