Add your PSAT math and verbal scores together to get your combined score on the PSAT. The verbal section of the SAT is graded separately, so do not add the verbal section of your PSAT score to the mix.
Place a zero on the end of your combined PSAT score to get an estimated SAT score. The PSATs are ranked on a scale of 20 to 80, while the SATs are ranked on a scale of 200 to 800.
Add your math, verbal and writing scores together to determine your “Selection Index.” The National Merit Scholarship Corporation looks at Selection Index scores in order to determine if students are eligible to compete for college scholarships.
