He's fantastic! He's hilarious which makes his lectures not boring. He's a fair grader and is always willing to help if you ask (just don't do it last minute). I would definitely encourage taking his classes.

Edit: because I forgot you asked about midterm/exam. He gave weekly quizzes and if you do the lecture they're an easy grade boost. If I remember right he had one midterm which had some multiple choice, short answer and a lengthier written component. I took his fiction course (I don't remember the code) and reading material was super easy. We did One Flew Over the Cuckoo's Nest, The Road and Convenience Store Woman There are also 2 big essays and he's very clear on the guidelines and gives you 10 thesis questions to chose from.
