Overall an okay professor, but an absolutely terrible grader. If you make a tiny numerical mistake at the beginning of a problem, you'll lose points through the rest of the problem and get close to zero credit. This means the midterm average was a D, and it's an non-curved class. It's also hard to get him to regrade mistakes he made, he's very obstinate.
Other than that he's pretty decent though.

Bauchy is very methodical. He never skips steps when explaining things. He has a French accent but he is easy to understand. Take this class if you want to understand things on a fundamental level. Exam difficulty is on par with what I have experienced at UCLA, so hard but not impossible.
