No it is not.


The percentile formula involves where the score is ranked (i) in an ordered list of scores, and the number (n) of scores. P = (100(i-.5))/n.


Given P, the percentile, and i you could find n. Given P and n you could find i. But you couldn't find the actual test score without the ordered list of test scores.
