I had him as a student back in the 90's excellent teacher.
Mengel does not care about making students happy, he merely wants to teach and that is all, he makes this very clear. That's what he's there for an that's what he's suposed to do. I respect that completely. I love 'em and I think he's hilarious.
i enjoyed his class very much. made me like science even more!
Everyone seems to dislike him except for me; I think he's great!
