I finally remembered my password here! Hallo old friends! I have a question. How do you know if you are taking PSAT10 or PSAT11? Just curious, as it probably doesn't matter much. My 10th-grade son's school offers PSAT for 11th graders, but they said if they had room, 10th graders could come and take the test, so I thought he was taking the same test as the 11th graders?
