The PSAT (Pre-SAT) is a test that is sponsored by Collegeboard and the National Merit Scholarship Corporation. Usually this test is taken in mid-October by Juniors in high school, but Sophomores are able to take it as well.

There are two main reasons to take the PSAT:
1. To practice for the SAT, which has similar math, reading, and writing sections. It will also give you a rough estimate of what you could potentially get on the SAT.
2. To qualify for scholarships, especially the National Merit Scholarship Program. *note, only Juniors taking the PSAT in their third year of high school are able to qualify for National Merit scholarships.

The test is 2 hours and 10 minutes long and consists of 5 sections:
Sections 1 and 3 are Critical Reading, have a 25 minute time limit, and consist of 13 sentence completion questions and 35 reading comprehension questions.
Sections 2 and 4 are Math, again 25 minutes each, and consist of 28 regular multiple choice math questions, and 10 grid-in questions.
Section 5 is Writing, is 30 minutes long, and contains 14 identifying sentence errors, 20 improving sentences, and 5 improving paragraphs questions.

Scoring 1 pt for correct answers
0 pt for unanswered questions
0 pt for incorrect grid-in answers
-1/4 pt for incorrect answers

The math, reading, and writing sections are then converted into 3 separate raw scores ( # correct – (.25 x # incorrect)). These scores are then converted to scaled scores between 20 and 80 (80 being a perfect score). *note, these scaled scores change from year to year, based on the performance of students taking the PSAT
The index score is then the total of all 3 scaled scores. A perfect score is 240, but the average selection index is roughly a 147.

With all of this in mind, it is important to mention that the PSAT can in no way hurt you. I mean this is two ways. First of all, this is not a difficult test, and is certainly not something that anyone should stress out about. And second, PSAT scores are not sent to colleges, and so therefore a bad PSAT score will not have a negative affect on future college admissions.
