Comments from Students

  • “Ideal. Learned lots, no needless assignments. Sungwoo was a brilliant and nice instructor, it’s thanks to him.”
  • “Definitely take it.”
  • “And the professor is great! Overall A++++++++!!”
  • “As someone who is very interested in the prospect of teaching, Sungwoo is a perfect example of how to do it right. His love for learning is infectious and he has a way of so charmingly expressing it in others. To focus on the work and the knowledge as opposed to getting a good grade is a philosophy that actually increased my mastery and achievement in his class. Cares about his students so much and he is only a grad student. So many professors who have phds and are tenured could learn a great deal from Sungwoo. I certainly hope to have him again in my upcoming years at Duke as well as to have the pleasure to be taught by someone as caring and charismatic as he. Great job Sungwoo!”
  • “It was great having an instructor and not a sadist for once. Really made it possible to learn without suffering. I learned the most under his instruction.”
  • “Professor Um really seemed to care about the engagement levels in class and was very attentive to arraigning a time for us to discuss problems I was having with a paper.”
  • “I love the professor a lot, he used video, conversation and powerpoint to explain the things that was hard to understand. And he support us in asking questions after class.”
  • “I really like the professor and the way he taught the course, especially with our discussions. It felt like a very free learning environment. His mentality with teaching the course was better than any other teacher that i’ve had as we could be taking notes one moment and then deep in a discussion the next- with the transition effectively instigated by the professor.”
  • “The instructor was great. His open-discussion teaching style and his great passion towards teaching philosophy has made him one of the best teachers I’ve ever encountered.”
  • “Everything was essential. There was no wasted lesson or anything that could be neglected; however, I wasn’t once worried about my grade because Sungwoo made it clear that he was only concerned with us genuinely learning the content. Sharing that sole concern, the grade came naturally.”
  • “Absolutely fantastic experience, nearly flawless in its execution. It is a class where you actually learn the content and become a logician, rather than just getting a letter grade.”
