While I can't say anything to make you stress less about your scores, I CAN pretty much assure you that you wrote it in cursive, or at least good-enough cursive. The guy sitting next to me printed his, and the proctors made him erase and re-write it after he handed it in (later in the day.) I think it's one of the things on the proctor checklist.
That does put me at some ease BUT----my test center was really shady lol. People were taking the MCAT on stools, no lefty desks, the temp was 90 degrees, we were ALLOWED to drink stuff during the test, people had timerss on the desk, things that beeped, and the list goes on lol.
I think we had our ten minute break before she even looked at every test lol. So, hopefully as ghetto as the place was, I hope I wrote in cursive lol.
