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.
I am a Freshman (9th grade) and I took the PSAT in October. I didn't do any test preparations at all. I just got back my score. Here is my score: Critical Reading-55 and Better than 86% of sophomores, Mathematics-51 and Better than 75% of sophomores, Writing Skills-62 and Better than 96% of sophomores. My Selection Index score is 168. And my Percentile (compared to juniors) is 80. Is this a good score for a Freshman?? Please be honest. And also, what is the average for a Freshman PSAT??
