on the PAT section of cracked PAT, I think the percentages are useless. They really don't tell you anything. On other sections like the reading comprehension section of crack DAT it gives you a much more accurate percentile rank. I would just ignore the percentile rank and just focus on your DAT score. You can also use the score conversion chart on the 2007 sample ADA DAT, this will give you an accurate percentile rank.
