haha raw score comment
The percentile score is for test taker benefit only. Since 19 was ~50%, then they will try to make that section harder on future tests to bring down the average. This is why you'll see on this forum posts where many DAT takers got rocked by a particular section, thinking it was much more difficult than the practice tests ... because it was. Same should be true for them to make the test easier if the average is consistently getting worse scores.
