PSAT scores are reported on a scale that runs from 20 to 80, 20 being the lowest and 80 the highest. This is a parallel to the SAT, which scores between 200 and 800 on each test part. If you want an idea of how youâll do on an SAT test, simply add a 0 to your score.
How PSAT Scores Work. The PSAT consists of three sections, each of which is scored on a scale of 20 to 80 points with 80 being a perfect score.A perfect composite score would be 240, while the worst possible composite score is 60.Like all standardized tests, the PSAT doesn't care how many questions you answer right or wrong in a vacuum.he 50th percentile of PSAT scores for high school juniors was 141 out of 240 in 2014, so if you scored higher than that you beat at least half the field. A score of 163 would place you in the 75th percentile, ahead of three-quarters of the field.
