He was a very interesting lecturer. His exams always gave you a choice of what you wanted to answer and I liked that (although it was time consuming) because you could show all that you did learn as opposed to focusing on what you didn't.
John is amazing! This class was extremely interesting and was definately the most useful class I have ever taken. The exams are not hard IF you read the textbook and go to class (take notes whilst in class!). As per the papers: LISTEN and WRITE DOWN what he expects of them in the first two classes. He's a very fair marker!
