You feel awkwardly guilty when you beat people in your class in a test that they studied a lot for and you didn't even consider studying. Amirite?

I would never feel guilty about doing well (I wouldn't brag either though). I suppose it's a rare occurrence so I have to make the most of when it happens.

if it is easy for me great. I never studied, just paid attention in class.

PSAT (and SAT for that matter) in a nutshell. Especially when my friends paid for prep classes...
