OMG that's so close! I thought they were curving it because 82 was the top scorer. If I got a 73 and top quartile, I'm sure you are too. To check, go on canvas on a deskto/laptop (can't see it on the phone), and it should say show class average, lowest, highest, low and top quartile.
Hi! I also didn't pass the challenge exam. Although it says I was on the top quartile. Maybe the other group of students who took it had higher grades. We'll try again next time.
