I don’t know what colleges want, but the second part of the above comment is correct. For national merit consideration, you need to have confirming SAT scores within a certain time frame (I think is is roughly a year before the PSAT was taken, but can’t remenber exactly) up until something like the fall of senior year. They also recently changed the rules, so that kids can use an ACT score for confirmation instead of SAT, but I don’t know details of the time frame (assume it’s similar).
