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.

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 does a good job of thoroughly explaining the course material. His exams tended to be difficult, and is due to the fact that he likes to test your knowledge of the concepts as opposed to being able to solve numerical problems, much like the homework assignments. Even though the midterm average was low (~D) , he was willing to change his grading policy to place more weight on our final exam. Although I didn't do well on the midterm, I was still able to get an A- in his class because of this. I would recommend his class to those who want to build a strong foundation.

He is very clear and goes over concepts multiple times. The midterm was good and he prepared us well. However, the final was very difficult. Make sure to study hard for that.
