Most of my student evaluation comments are pretty short. Like "GTO - Great Teacher Otto!" But, the one below goes into quite a bit of helpful detail.
"Otto Pohl is one of my favorite instructors!!!His classes are always interesting and I take out a lot of new things. He always ready to answer any question and his answers are clear. He is very polite and tries to invlove all students into class discussions. I would strongly suggest to other students to take his classes!"
