What do you think about me having a prof in 3rd year that didn't know the difference between 12am and 12pm?
what was your experience with him like?
Me made me feel stupid during the third class when he said it was noon although it was 4pm.
Probably your professor said it by mistake. You don't need to bash him for some silly mistake.
I get weird dreams and sometimes I can't even tell what time it is and feel like I'm in hell. Also, I don't think he's an idiot, he is just an idiot for me.
You should not think less of your professor just because he said something wrong by mistake. Everyone does this from time to time. It's likely that he just had a lot on his mind.
