There are only a few differences between the PSAT and the SAT. Both tests are completed in 2 hours and 15 minutes. The scoring scales differ slightly between both tests, with the PSAT maximum score at 1520 and the SAT maximum score at 1600. The PSAT serves as an introductory version of the SAT with marginally easier reading sections and less complex math. Scores from the SAT will be evaluated for college admissions. PSAT scores do not directly influence admission decisions; however, a high enough PSAT score can qualify a student for National Merit Scholarships.
