Probably the best math professor there is at UCLA, his teaching style is reminiscent of high school teachers - spoon-feeding, which is great because you will understand everything if you go to class. Even if you don't get the stuff there, just copy down the extremely-comprehensive notes anyway and read it over again when you get back and you'll understand it perfectly. College would be a breeze if everyone taught like him.

Fall 2015 - I took his 33A in my first quarter and he made me want to transfer away from math major. I couldn't follow his lecture at all. When I asked the students sitting around me if they understood the lecture, they all said they had no idea what the professor was talking about. Some upperclassmen said Penneys was the fastest lecturer they'd ever had. Although he is interesting and the class was vibrant, I will never take his class again! I studied everything by myself and went to TA and math tutoring center nearly every day and got A-

Winter 2021 - Absolute unit of a professor. 3 extra credit opportunities (which didn't matter for me) by attending random lectures. Recovers easily from mistakes (my 2021 homies will understand ;) Easy exams if you did the homework, similar solutions and repeat problems on midterms/finals. Just take it with him and you'll enjoy it.
