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.
