LeGuyader is an interesting professor. You can easily tell that he loves to teach... His passion, however, is greatly outweighed by his inability to convey concepts in a clear, concise, and understandable manner. Or perhaps I should rephrase - he is unable to explain elementary and fundamental concepts to people who actually need an introduction to accounting and finance. There were people in the class who already knew finance and they seemed to get a great deal out of his course - after all, he is a hotshot veteran investment banker who kicks total ass in his business (no cynicism intended). He definitely knows what he's talking about both theoretically and practically.
So if you understand finance to begin with, you'll learn a lot and the course will be easy throughout. Otherwise you will toil through his lectures and come to find on review day with the TAs (who are good) that what you've been studying and trying to understand all this time is not at all what's going to be on the tests. You'll most likely have to work hard throughout the course unless you're good at theoretical math (easy - no calculus), as in understanding the background behind how financial concepts function in math.
I greatly appreciated his passion though. If you make an effort, you'll probably end up with a respectable foundation of finance. I would recommend him if you're willing to study for it.
