Good class! Professor is very organized and experienced with the material.

The tests are based on the lecture material, so it is important to attend the lectures. I would say the midterm and final questions are quite fair, you should do fine if you take good notes in class (he also provides study questions for the final).

There are 2 essays based on the readings, which are not too difficult as well.
He uploads all the required readings, and you could find the books in the reserve, so you don't need to purchase any books.
