I'll take a closer look. I might have gotten credit. Do you usually get credit for pass/fail classes?
EDIT: I just googled and it looks like passing a pass fail usually results in getting credit, and not passing results in no credit. For now, I'm going to enter credit for pass-fail classes that I passed (which is pretty much all of them). This will make a difference in where the cut-off is between freshman, sophomore, etc. statuses...
