Easy A. Quizzes and tests were all group work. Hw was extra credit. Barely took role, but he really doesn't care if you come or not. I got an A and did really nothing. If you are into math and really actually want to learn, you can because he teaches great :)

Zach Galifianakis-style delivery with Norm McDonald punchlines. 100 is an easy class, and his jokes are hilarious. He does not use Mymathlab, all homework is done on paper, from the book, and is extra credit. If i had to pick a professor to take all the way through Calculus, it'd be this guy.

Math's been a subject I've struggled all my life and this teacher made it bearable. HILARIOUS. Super easy A class since quizzes and some tests are done in groups .HW is extra credit. Though if you aren't a fast paced learner don't take him since he teaches the material by doing a lot of the HW questions.

It took some time for me to adjust to his teaching style because he tends to tell lots of stories or sing songs during the lessons. He doesn't require you to purchase the textbook as he goes over the sections from the book in class. He doesn't assign homework or takes attendance. He is very understanding and doesn't want to stress his students out.

Do not ignore the most recent reviews for the professor. He does not teach.
