Hi PursuingMD,
I think you're right about who will know how many times you've taken the MCAT... medschools will not know what you've voided, and it doesn't matter what the MCAT people know, so long as you give them the proof you need to take it again.
I think it is a plus that your Physics went up 2 points, b/c it shows you can improve, and will probably improve again. I think it's fine if your bio didn't change, you can change it this next time. And with your verbal, changing your technique right before the exam probably did it.
The next time around, finish studying EVERYTHING early, and leave yourself 3 weeks to just practice. I think it makes a huge difference. My score went up 6 points btwn the 2nd and 3rd time just bc i practiced so much more. That's what I needed. Even down to the last week of the exam, i took 2/3 of an exam every day before the actual test. Then i'd go back and see what i missed and why, and review those topics. I also sat down 2 saturdays before the exam, at the location I was assigned to, to take full length exams (though not the same room). This helped a lot, b/c by the time I took it, I was kind of in the mode---it was just another test. Removing the fear for me was a big deal.
If this helps, these were my scores for all three times.
5V, 9P, 9B, R = 23R
6V, 11P, 9B, R = 26R
10V, 12P, 12B, Q = 32Q
Verbal was my problem as well, and I think with the sciences, my problem for the first two times was i never went through all the material b/c I was trying to study everything in too much detail. The third time, I relied heavily on Flowers and Silver, fleshing it out with Princeton Review, and the MCAT physics book, and I at least got through all subjects.
Definitely practice this time around though. From what you've mentioned, it seems perhaps that's all you were lacking--to learn how to apply everything in your head that you studied, to answering the MCAT questions.
