On my practice test today, I scored 26/30 on my gen chem section, and the feedback said I scored a 20 for the chem section. So, if 26/30 only gives you a score of 20, then you have to be almost perfect to score 21+??????? Just seems like there isn't much difference in 20, 21, 22, etc., if the only difference is 4 correct answers......
 
There is a DAT score estimator PDF file on the ADA website (google will find it for you) that estimates that if you get 26 right in general chemistry that you'll get a score of 20 for the section.
 
these are just estimates.. im pretty sure its based on how well everyone else does..
 
Yeah these are just standardized values that can be used for general grading of practice tests (topscore actually uses the exact grading rubric from the ADA website). If you look closely you'll notice that even if you get all of the questions correct on some sections you won't get a 30, while on the real test those people who get all the questions in a section correct will usally be in the 99 or 100 percentile and get a 30. If an absurd number of people are getting perfects on the same section then the highest possible number to get on a section won't be 30, it'll be dropped to 29 or 28 but it will still show as the 99 or 100 percentile.

Wow that got pretty convoluted, hope it made some sense.
