He is the BEST professor I've ever met in UCLA! His lectures are clear, his tests are interesting, but the most important thing is, Butler really cares about students. He is so devoted into teaching and still spends a lot of time improving himself. What I learn from him is more than math!

TAKE BUTLER! Professor Butler is a hilarious and caring mathematics teacher. I enjoyed going to all of his classes this quarter. He often makes hilarious remarks during class and is always excited to be teaching. He has funny T-shirts as well...some of them are math-related.

He was the first math professor at UCLA who I truly understood and actually felt excited about. His tests can be on the difficult side, but if you keep up the hard work, attend his office hours, and study a good amount you should be fine. He also tends to give hints on his test that are really helpful, but only if you understand the hint ;) If you try to do the problem the traditional way, it may take forever or seem impossible. BUT if you understand his hint, it can be easily solved in a few lines. Often his tests seem hard while you're taking them, but then when you see the answer key you're like, REALLY? COME ON! But learn from this. Learn his ways..haha.

Finally, take covel tutoring with this class also if possible. I found it to be very complimentary to the course.
