To some extent everyone hates some aspect of school - the most obvious being a class you're taking. So, what's everyone's wost?
Mine would be programming. Hate it with a passion. It's a mandatory technical course, so I have to take it, but if I could choose to opt out, I totally would. Oh, plus, my prof spoke French and barely any English, and she couldn't even program properly herself. Yeah, fun. Not!!!
So, what's your worst?
