Since the PSAT and SAT have been revamped, the percentile scores from last year to this year may not be the same. This article has some very interesting information on how the percentile score of this year's PSAT may be inflated since it ranks the test taker's score against all students in the grade (including students who did not take the test and would have presumably scored lower), rather than the actual students who took the test (as has been done in previous years). The cutoffs for the National Merit scholarships will also change compared to last year since not only did the scale for the test change, but also how the percentiles are calculated.
