One of the most laidback course I've ever taken at Queen's. Used the lectures to nap between 2-engineering classes (and got my friend to use my iClicker for me).

He says to focus on lectures, but most of the lecture was just filled with pictures, and he rambles a lot. Final wasn't easy, but if you memorized everything (which I didn't) you'd do fine. Unfortunately, I think my A was destroyed by that exam. Lectures were very boring.
