The PSAT is the Preliminary Scholastic Assessment Test. It is a two hour exam given once a year in October. Each subject is scored on a scale from 20 to 80 points for a total of 240 maximum points.
Students often take the exam as sophmores and again as juniors.
PSAT scores are not sent to college admissions department. The College Board Online offers additional information and practice exams, as well as test-taking tips and scholarship information.
