No it is not.<P>
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.  <P>
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.
