I only have 2 grades in and they aren't horrendous but aren't great (B, B-). I don't intend to discuss them w/anyone beyond being super general, but a friend of mine today told me she got an A in the class where I got the B- (I didn't say what I got, she just up and told me her grade), and it pretty much made me feel like crap. I'm sure she didn't intend that at all and was just excited about her grade, but still, it literally made me feel stupid and unmotivated. So....I'd definitely advise not sharing your grades even with friends.
