That seems awfully skewed, I personally wouldn't rely too heavily on it considering that there are only 2 subjects in that data pool who scored below 500 which makes it very heavily influenced by those who did well on the MCAT. I'd like to believe that is how it is because my diagnostic of 497 puts me at about 508 on the real thing, however, I'm not putting much money on the chart there being too representative. Kaplan certainly deflates scores by a good amount, but even using the chart I wouldn't consider it to be anywhere near as representative as anything by the AAMC.
