The guy you asked, “Hey, did you do well on the test?” and if I said, “Yeah,” it meant I got 100% and if I said, “No, I failed,” it meant I got 99%.
Basically, I was the infuriating smartass. But even I had to make “educated guesses” from time to time. In other words, a shot in the dark. And these kids seem to have done the same thing. While their answers aren’t technically correct, I just can’t help but give them props for it anyway.
