<p>My DD is using an old Barron's How to Prepare for the PSAT//NMSQT book to do practice tests. She can't find info on how to score them. I poked around and don't see any instructions on that either. Of course, I don't know much about the PSAT test. Does anyone have any advice on how to calculate a score for the PSAT? Is it just the number correct? Points off for wrong answers? Please help. Thanks!</p>
