It was, and we had a GA for the lab (Grad assistant) and he was one of those people who may have been really bright but was a horrible teacher, so he couldn't really explain how to do any of it and couldn't understand how anyone struggled, but he was also one of those people who couldn't admit that he made mistakes. So I remember him doing this one problem on the board, and he made a mistake and one of the guys in the class tried to point it out and he made up some lame excuse, saying it wasn't wrong, just a different way of doing it. So then he got to the end of the calculation and couldn't figure out why he got the wrong answer. We were all trying so hard not to laugh because he had made such a big deal about how we were all just lowly students and he was a GRAD assistant and he knew more than all of us and he had understood the theory of relativity at 5, so none of us were as smart as he was...and then WE all had the right answer and he made a mistake with his calculation. I LOATHED that class.
