    "comment": "Yu Chan is probably one of the best math professors here at UW-Madison. He provides excellent and clear class notes on Canvas along with so practice problems that are similar to exam questions. The exams are so very doable and easy if you study his notes. In general, easy A with a little effort. His jokes are also good lol. Thank you Yu Chan!",

He makes sure that everyone in the class (like all 200 kids) understands what he's teaching, and of course they did! He was so amazing. I think I'm in love with him.",

    "comment": "Just a genuinely good person. I was in a bit of a rough spot with my math before going to him, and he really helped me get back the confidence and love for math that I had lost. Easily the best math prof I've had so far at Madison, very clear and simplifies things down to the point that you can actually apply it yourself.",
