I'm reviewing Michael because I feel the prior review is unduly harsh. Michael was a tad irreverent, lax and chatty with the class. Not my style. He was, I believe, an engineering grad student and his expertise in chemistry was a tad shallow, but it's not HIS fault he was asked to TA a chemistry class. His quizzes were very straightforward and I thought they were largely fair. He didn't seem to put a whole ton of effort into the class but that's par for most TA's. Michael's an extremely laidback guy who cuts up with the students a lot. I worked hard and was treated fairly. No complaints.
