This guy is the worst. He is an idiot and thinks he know what he is doing.

I cannot believe he is rated .83 on hardness scale...His tests were more than fair, and will help you on any homework question you couldn't solve. Really nice guy and good lecturer.

Green offers decent analogies and anecdotes to help students understand the usages of the crap which is always nice. His lectures are pretty much from the book, but sadly the book sucks. It helps to go to class to see the actual proofs and Green does a nice job breaking it down without spending too much time explaining trivial stuff we already know. He also offers brief alternative ways to prove things if the class gets confused.

All in all fair professor. Tests are hard. Be prepared to think outside the box.

The course material was very interesting, and I felt like I learned a good amount of material. Tests were not always representative of homework, but they were definitely do-able and fair. It was a lot of work getting all the homework done, and since there was no TA there was no way to know if your solutions for ungraded homework was right. The take-home final was pretty difficult. His office hours were good because he's very friendly and offers tea and cookies. I'd say take him, but be ready to spend a decent amount of work with homework and stuff because he seems to like to assign a lot of homework every week. But, he really isn't a 9 difficulty. I'd say lower because if you put the effort in, he will reward you.
