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.
The PSAT scores range from 160-760 each in EBRW (Evidence-Based Reading and Writing, the verbal sections) and Math (both the calculator and non-calculator sections) so the highest score a student can earn on the PSAT is a 1520 and the lowest is a 320, whereas on the SAT, the combined score ranges from 400-1600.
