Moving to PCAT discussion sub-forum:
As for your question, you will definitely see a Percentile Rating or "PR" score that places you in comparison to other applicants over a span of 5 years. The SS you are referring to is the Scaled Score or "SS" and this is based on the # of items you actually got correct within each specific section of the test which can range up to 600 as a perfect score.
The PR is a number that ranks you against your peers. For example, if every applicant from 5 years ago to the present time missed 2 questions in every category and you only missed 1 question for each category, then by the PR rating you are the 1% that beat the score of 99% of your peers (thus, you would see a PR of 99%). On the flip side, if every applicant missed nothing and you merely missed 1 question, then by default you were beat by 99% of your peers over the past 5 years putting you with a PR score of only 1%.
Theoretically, if you get over a 50% then you scored better than half of the applicants. To be considered competitive in times past you would need to have a PR score around the 70th percentile or higher.
So, if your SS score average is somewhere around a 380, then by definition on a 600 spread-scale your Percentile would be very very low.... In simple terms, that tells the admissions committee that out of approximately 60,000 applicants, around 75% or more of them did better than you.
If you wish to see an example scale of a previous 5 year cycle back in 2016 (nothing much has changed with the layout) here is a link:
