I looked at several averages. No, I didn't actually sit down and calculate everything, I just roughly averaged the numbers.
Averages:
1. Total Kaplan scores
2. Total AAMC scores
3. Combined Kaplan and AAMC (I mainly used this one)
4. The three Kaplan section scores
5. The three AAMC section scores
6. The three individual section scores Kaplan and AAMC
Make sure that your section scores are not jumping around. For instance, you could get the same total score, but one time your PS is 13 and your BS 8. The next time your PS is 8 and your BS is 13.
