Quality 1/5Difficulty 4/5

Unable to understand. His English is virtually unintelligible.

Though he seems like a nice guy, attending his lectures won't help or hurt your grade in the class. Unless your somehow able to understand him. Having a good TA who does review sessions is the most helpful part of the class. If Beth M is a TA, TAKE HER and you might learn something.

Quality 1/5Difficulty 5/5

The worst professor. Doesn't speak any english and just smiles if you ask questions. Lectures are useless. Must read book and good TA. Can honestly say I have no idea how to apply anything I learned in this class to the real world. Horrible grading system. Exams are out of 20 points so you cannot afford to miss any problems. Don't take this class.

Quality 1/5Difficulty 5/5

Absolutely terrible professor. Cannot understand anything he is saying. Lectures are just problems from the book. He is terrible at explaining things and always skips steps in his work in lecture. I learned more from my TA and the kid I sat next to than this terrible professor.

Quality 1/5Difficulty 4/5

Hard to understand, all depends on your TA (like a lot of math classes here). Be prepared to teach yourself and get help outside the classroom

Quality 5/5Difficulty 4/5

Did a good job for this difficult class. First and second exams were fairly easy with 3 or 4 problems out of 5 being right off the homework. The final was much, much ore difficult. Overall, good professor.
