Under what circumstances should I void my MCAT? Is it that bad to have a 24 or 25 show up on your MCAT transcript even if you scored in the 30s the second time?
I would agree with Jepstein30 - you never know how your final score will turn out to be.
Be aware that your real score will not be very far from your AAMC test score. Especially AAMC #10 onwards.
I would say follow your AAMC average and your gut. If you truly think there were large parts of the test that you just blanked, then I would void. But if you just have a bad feeling, then don't.
