Kyeongwon Lee STAT410 Expecting an A- Anonymous 12/13/2025	I feel bad doing this because the professor is genuinely a kind person, but he is truly a horrible professor. What he teaches in class and what shows up on midterms and quizzes could not be less similar. When he starts teaching a new topic, his explanation is purely mathematical notation and proofs. Not a minute of the lecture is spent explaining why this content makes sense conceptually (I mean it's introduction to probability, talk about drawing cards from a deck or something please I'm begging you). Even the most simple topics at the beginning of the class (I'm talking how many ways can you rearrange the letters ABCD) are explained abstractly. When I go to class I learn nothing. The reason he's not a one star is because I believe there is a way to do well in his class, and it can be summarized very easily: problem sets and ChatGPT. Here's what kind of worked for me: plug his 50-slide-long notes into ChatGPT and tell it to generate a page long summary for each chapter (about 3 chapter per unit), ask Chat abt anything you don't understand. Then, do the problem set based off of those notes. Luckily, almost every question on quizzes and exams are drawn directly, NEARLY WORD FOR WORD, from these problem sets (I basically just memorized every single problem set). Finally, pray you beat the average and get curved up. I'm sitting at a 90 right now, taking the final in a few days, and am genuinely beyond stressed about it because if the final isn't like the problem sets I am beyond screwed (so maybe an expected grade of an A- is optimistic).
Kyeongwon Lee STAT401 Expecting an A- Anonymous 12/12/2025	KYEONGWON LEE: Kind and understanding instructor who is able to address student concerns. There is more to be done to better this course, since it seems he is relatively new to the university, but it wasn’t bad towards the end. Things just got better. LECTURES (Rating: 4/5): Lectures are primarily based off of PowerPoint slides. This isn’t the professor’s fault but mainly that of the statistics department. It would have been more appreciated to have a curriculum where we have some practice in lectures. This eventually changed towards the end when we sent him emails. See the “Homework” section for more details about the R sessions, which were held occasionally. DISCUSSIONS (Rating: 4/5): It would’ve been nice to have two discussions for this class. We go over a practice worksheet and then head into a quiz (we leave early afterwards). The quizzes should only take 15 minutes, so it would’ve been more ideal to have the extra 5 minutes to go over worksheet problems. HOMEWORK (Rating: 2.5/5): There was only really one homework assignment for the course - an R Project that was worth 10% of our grade. The R Sessions that were intended to prepare us for this project did not help much, and it was not fun having to learn an entire programming language from scratch just for this project (I am new to R). I HIGHLY RECOMMEND TAKING DATA 110 AS A CO-REQUISITE IF YOU TAKE THIS COURSE. QUIZZES (Rating: 3.5/5): Quizzes were meh. They were given weekly in discussion and were based off of the practice problems. The class group chat panicked at first because of how unprepared the class felt for the quizzes. But eventually the averages got better over time and even I was shocked at how good I was doing. Because some quiz means were so low he plans to drop the lowest score. EXAMS (Rating: 5/5): The exams were not bad, I’m just dumb. (I also have neither the dorm nor the time to study.) Dr. Lee allows you to bring a formula sheet in for the exam. One side of a sheet for the midterm, and the whole sheet for the final. Oh, and did I forget to mention there’s extra credit? OVERALL RATING: 3.8/5 Structure for Fall 2025 - R Project (10%) - Quizzes (30%; weekly, lowest dropped - we had nine) - Midterm Exam (25%) - Final Exam (35%)
Kyeongwon Lee STAT401 Expecting an A Anonymous 12/12/2025	This course was kind of rocky at first but if you do the practice problems and have all of the important formulas written down on a formula sheet that you are allowed to bring into the exam you will be fine.
Kyeongwon Lee STAT410 Anonymous 12/11/2025	I want to start off this review by saying that the professor is a very nice guy. He genuinely has no malintent. However, there are certain shortcomings that took place during the course, which is rather unfortunate. I'll start with the most recent and move backwards in time. - The last two weeks have been conducted and have not been focused on our imminent final exam, rather, using R and its applications for statistics (material we are not assessed on). This honestly sucks, given the fact that it is unclear what exactly will be covered on the final. Again, the final we have in a few days. - Before these last two weeks, there was a total of three weeks where the professor was not present, and we had an alternate instructor. These instructors covered the most difficult material in the course, and since they do not directly oversee the exams, it was hard to understand what exactly was and wasn't exam-relevant. Now, he did provide legitimate reasoning as to why he was not able to attend our class, just not great, given out of the 15 weeks in the semester, we have not had substantive lectures for 5 of them. The biggest concern for me is what to study for the final. He gave us six files for practice problems, however, there are some content differences generally between this and the other final exams on the testbank. Would be nice to get some closure on what exactly I should be focusing on. Pros of the course: quizzes and exams are fair, if not helpful given they have been based off of practice exercises and we have been allowed to use a cheat sheet on the midterms and upcoming final. He is approachable and can be helpful.
Kyeongwon Lee STAT401 Expecting a B- Anonymous 11/03/2025	I'm not sure what's going on in this class anymore. The STAT department needs to do something about its courses and professors. First there's the nightmare with Dr. Zheng's STAT400 class and Dr. Williams teaching STAT410 in the most brutal way, then there's this. Dr. Lee does not seem to go over the concepts effectively at all, instead redirecting us to his practice worksheets whose answers are typically not gone over. This makes doing them a waste of time as we can't even check our solutions to see where we went wrong. The quizzes in this class also have abysmal averages (two quizzes didn't even get a PASSING mean, with one being under 50%). This shows how unprepared many of us feel, even though the quizzes were pulled directly from the practice worksheets. The funny part? ALMOST NOTHING from the lectures shows up in the worksheets, lecture is all PowerPoint slides with conceptual stuff but the discussion is entirely applications of these concepts, which wasn't taught very well. The professor also seems to be very static with learning and doesn't seem to change things up very well. Our midterm review was literally just the professor going back through the very first set of slides and jumping through things, rather than doing practice problems that would be useful for the exam. Recently, we have also had a sub instructor cover the class, and the sub literally went BACK TO THE START of a 90-ish slide PowerPoint that we were MIDWAY through, jumping through slides very quickly. The class GroupMe had also freaked out several times when there were quizzes because everyone felt so unprepared. I hope there's a curve in this class. If so, I'll reconsider my current rating.
Kyeongwon Lee STAT410 Expecting an A- Anonymous 06/12/2025	READ FOR DETAILS I was debating writing this review or not, but I decided that it was worth writing. Overall, he is an alright professor. He is not the best lecturer, and his lecture notes are impossible to read, but he goes rather slowly and you can very easily keep up by following the course online with YouTube lectures. He gave one midterm, then cancelled the second one and moved all its weight to homework. This naturally caused grades to spike in the class. To make up for this, he gave a really awfully hard final that we were not prepared for at all (no practice, just told to review the homework. Spoiler alert, it was nothing like the homework.) I literally opened that final and couldnt answer a single question. The average was a 23, with a high of 65, so every single person failed that final. However, I will contest the current one star rating. I do not think he is deserving of this at all. I am rating him 5 stars not because he is a 5 star teacher, but because 1 star is just unfair. If I would rate him, I would give him a 3.5/5 for the following reasons: Pros: - Very kind and reasonable guy who is willing to try to explain anything and can accommodate almost anything - Tries to make the class manageable - Homeworks are pretty easy - Grades very generously Cons: - Lectures are hard to follow because of his thick accent, and his handwriting is impossible to read which makes his notes useless - Gave a curveball final that everyone failed, which was not a good call but honestly I get why since the average grade in this class was >95% before the final... Overall, if you take him, I expect him to change up his teaching style massively next time he teaches. This was his first semester here I believe. I found the following YouTube series very helpful for this course, and would highly recommend regardless of what professor you end up taking: - Probability Theory (Bright side of Mathematics) (Good overview of general theory) - Intelligent Systems Lab probability playlist (good visuals) - jbstatistics (Goes over pretty much everything in an approachable manner, really demystifies a lot of the stuff) - 3blue1brown (Amazing visuals and good for selected topics to develop intuition)
Kyeongwon Lee STAT410 Expecting an A+ Anonymous 05/23/2025	If I could go into the negative stars, I would. He is a generous and funny guy but boy is he a horrible teacher. He will talk and messily write on his iPad quickly the whole lecture with the addition of ranting about stuff outside the scope of the class and writing on the chalkboard, then writing OVER what he already wrote on the chalkboard. He never answers questions directly, and I literally would be more confused after asking a question and getting an “answer”than before I asked it. 7 homework’s weighed 49% together, 1 midterm weighed 25%, and the final was 26%. The homeworks were medium difficulty the whole semester with some really hard problems included in the later homeworks. The midterm was basically the relevant homeworks but problems people never looked at (for each homework, 8 problems total, 4 required, and you can choose 2 from the remaining 4). THE FINAL. it was literally the worst college exam i have ever taken as a STEM major. For context, I studied for 3 weeks and I was speechless looking at every single one of the 8 problems. ONE PROBLEM HAD 8 PARTS! The average was a 23.81% with a low of 6% and a high of 65%. talk about a distribution. do not take this man. the curve was generous but the journey to get to the end was not it.
