Although it is obvious that Song is very smart and knows his math, it is hampered by his thick, impossible to understand, accent. I sat in the first couple rows every class and I still could not understand one word that came out of his mouth. I often found myself zoning out because all I heard was background noise.
I went to every class thinking that I would understand him a little better after each one, but I was wrong every time.
Having such an impossible to understand professor, I assumed my discussion TA would be able to help out a lot. It turns out that he was worst than Song, if that's possible. Ngoc Le, just like Song, is a smart guy, but his accent and stuttered made it worthless going to discussion.
The only reason I got an A in the class is because I remembered everything from my AP Calc class in high school. If you don't feel confident in math then I highly recommend getting covel tutoring.
Run, don't walk, away from this professor.

The only way you'll survive this class is if you know calculus beforehand. His tests are fairly easy and the curve is very low, but his accent is horrible, impossible to understand. I just never went to class

Let me just say that I took this class in high school and had a 4 on the AP exam.

I am so glad I knew the material. It's very tough to understand his English; I don't know what I would have done if I hadn't taken it.

The first midterm is easy, but it gets progressively harder from there. He told us to memorize proofs that would show up on the test, and it turns out, they didn't show up. Average on the final was under 65%.

I ended up with a B in the class. Class is curved at the end, after all points are added up, median is a B-.
