Best to get him as an upperclassman as he is more open with the class. Lots of fun in BC calc and I think almost everyone got a 4 or 5 on the AP test.

Awesome. Sometimes quirky, but cool. He has a subtle sense of humor, and you have to be rather well-read to understand some of his jokes. Very clear about concepts when teaching, too.

He's more knowledgeable about literature than any English teacher I've ever had. He does not patronize his students; rather, he treats them as equals, even though he's intellectually superior.
