It's not easy to write an evaluation for Catton because he wasn't here half of the quarter due to medical reasons. When he was here though, he gave nice presentations. However, Catton tends to sidetrack a lot when he talks. He also proposes a lot of work for students to do, but at the end, he doesn't check it or things never happen. Anyways, if you are a MAe student reading this, I highly recommend 133AL. It was a fun class but also a lot of work. Make sure you have hard working groupmates - otherwise you'd be stuck doing all the work.
I took Professor Catton for MAE 157 during Fall Quarter 2013. His lectures can get very boring and off-tangent at times. But its fine, since the quizzes in the class are based off the lab manual/powerpoint slides from another professor. For lecture courses, I wouldn't recommend Catton, but for a lab class, his class isn't that bad and I feel that the grading was nice. Also, he is a very knowledgeable man, but isn't very good at lecturing. As I mentioned, there are quizzes before every lab. To prepare for those, just read through the lab manual andor powerpoint slides. They consist of three questions and are not difficult. Most questions are based off the objective of the lab, simple equations, etc. For the lab reports, there were three group lab reports, four individual summaries, one individual lab report, and one error analysis HW assignment. Not bad as long as you do everything that is required for the reports.
