Comment:
He has a forgiving grading system (basically worst test score gets dropped) and it saved my grade. Homework is mini quizzes on lecture content that are worth points, but you only need around 2/3 of them right to get full points in this category and they're helpful while studying. He is super friendly/nice and I'd 100% take a class from him again!

Comment:
With new online learning at UW and events outside of class that have distracted me, I haven't interacted one-on-one with Prof Yoon; this is one of my biggest regrets. His teaching style is amazing, and his correspondence and interactions with the class are unimaginably considerate and caring. This class is hard, but he makes it so worth it.

Professor Yoon is the best professor I have ever had in UW-Madison. I would like to provide more comments about his lecture. His lecture is very clear, in-depth, and inspirational. I always found his lecture very easy to understand. Even though he mentioned textbook content may be tested, if you fully understand his lecture, you will be good.

I loved having Prof Yoon. He is without a doubt my favorite professor I have had thus far at UW. He made online learning so manageable and his explanations were always crystal-clear. If you have a chance to take this class with him, DO IT! I promise you won't regret it. He's a gem.

Yoon was honestly such a kind and accessible teacher. In a class this challenging and with the stress of online schooling, he managed to brighten the days we had live lectures with his cheery and helpful personality. Truly happy that I was able to be a student of his! His class was also the most organized class I have taken, in person included!

Comment:
He is pretty enthusiastic. He ask us to learn through pre-recorded video lecture and he use the class for problem solving and group discussion, which is a really effective arrangement for ochem. Hes explanation for problems is always crystal clear. He encourages students to explore their own ways in problem solving and fall in love with ochem.

Comment:
I think the best words to describe Professor Yoon are optimistic, patient, and inspiring. His passion for chemistry made me appreciate the subject more, not only because of his obvious excitement, but also because of how willing he was to answer all questions. I also enjoyed his pep talks; sometimes I felt like he was my chemistry therapist.

Yoon is AMAZING. Literally the best professor I have ever had. Ochem is supposed to be challenging but he made it so much easier to understand. Honestly made me love ochem (or I might be crazy idk). You can tell he cares a lot about his students and wants everyone to succeed. Take this class with Yoon, you won't regret it.

Professor Yoon was the best professor Ive had to date. Hes a very thorough grader and thoughtful professor and hes one of the best chemistry professors at UW. It was a real pleasure to have him as a professor. If you have the chance to have him as a professor, dont take that for granted and ask loads of questions!!! Its helpful :)

Professor Yoon is an AMAZING professor! Probably one of the best one's I've had at UW. Especially for a class as hard as ochem, he makes every topic so much easier to understand and puts in so much effort to make sure his students succeed. 10/10 recommend!

Professor Yoon is by far one of the best instructors Ive had at UW, despite teaching one of the most notoriously feared classes in the department. Hes an amazing guy and fair grader who cares a lot about the well-being of his students.

Dr. Yoon is excellent. I dropped 345 in the spring semester and had Esselman. Night and day comparison. Yoon's exams are very fair. During the pandemic, Yoon was incredibly accommodating and understanding. He actually cares about is students and is so prompt to respond. In such large classes, I have never seen such passion for helping students.

He was an absolutely AMAZING professor this semester!!! He is always willing to help you out if you don't understand the material. His exams are definitely challenging, but that is part of what makes you work harder to succeed. Overall, I HIGHLY recommend him for Chem 345 in the future!!!

Prof. Yoon is the best chemistry teacher I have ever had, I took second semester organic chemistry with him and he made everything seem so straightforward somehow. I would highly recommend searching him out for any of his chemistry classes. He also cares so much about his students, even in the online format you can tell how kind he is.

Tehshik is a phenomenal professor. He cares about his students and the subject matter. The content is challenging (as with any 500 level class) but he will work hard to ensure that you have a complete understanding. 10/10 would take this class again

Dr. Yoon is the best chemistry professor I've had at the UW. His lectures are amazingly clear and he's always willing to answer questions and help you out. Homework is optional but the more you do it the better off you are on exams. If you can take a class with Yoon do yourself a favor and take it.

Comment:
Tehshik Yoon is one of the best lecturers I have ever had in any class - I'm an exchange student from University of Sydney, perhaps rivalled by another lecturer I had at home but it would be a close call. The only minor issue I might have with his style is that he can be a bit fast but is clear, very helpful, and likes upperclassmen (ie 547).

This was by far my favorite class taken at UW-Madison, Professor Yoon sincerely cares about student success, is passionate about teaching, and is an organic chemistry master. He also is great about answering questions in class. You need to attend class and pay attention, but if you put the effort in you can certainly succeed in the course.

Comment:
Honestly took the class with the expectations of it being extremely hard especially since I took it was the lab (344). The lab turned out being the funnest most stress free chem lab I've taken so far and helped SO much when you study spectroscopy in 345. Yoon is by far one of my fave chem teachers and made 345 very interesting and challenging
