Comments:DSC 43C8 - Dr. Han is far and away the worst teacher I've had during my time at Baylor. He has a very thick accent and is hard to understand and also mumbles, making it even more difficult to hear. He teaches in a very disorganized way, often making drawings on the whiteboard and not elaborating on them. Any time he asks the class a question, we have to ask him to repeat himself multiple times to know what the question is. His exams are unreasonably hard and regularly have failing averages and do not receive a curve. The saving grace for this class has been the homework and projects. For some reason, despite how ruthless his grading is on exams and quizzes, you will get a 100 on each homework or project provided you submit something. The projects usually take a long time to do, but as long as you do them and your slideshow has the right number of pages, you will get a 100. I recommend prayer for all of his exams. There was not a single A given out on his exams this year. I would say do not take, but hes the only one who teaches Big Data so you're stuck with him. Good luck and may the TA's grading be ever in your favor.  - Grade In Class:A

Comments:CSI 2350 - I don't usually leave comments but I absolutely had to for this class. Dr. Han is hands down the worst professor/instructor/teacher I have ever encountered so far in my years as a student: he might be smart and accomplished in his career, but he has absolutely zero teaching capabilities whatsoever in his arsenal. Firstly, this class (CSI 2350) is a required prerequisite course for anyone majoring in Data Science. Which means if you are majoring in Data Science, there is no possible way to avoid Dr. Han as he teaches the class “specialised for Data Science students”. To start off, Dr. Han's accent is extremely thick and he compounds it by not talking very loudly, so it basically sounds like he's mumbling half the time. Being that I am Asian, I sympathise with him, but I cannot give him a pass for this as he is an educator. This isn’t just a superficial complaint, he literally can be impossible to understand at times. He is super disorganised and didn't follow the syllabus at all: looking back I should’ve noticed something was off when he listed the “topics to be covered” without actually mentioning what order he would cover in them or when he would cover them. However, the structure of his class made it feel like there was absolutely zero connection between the subjects and he appeared to just be jumping around in topics that had little to no connection to each other. His teaching abilities themselves are sorely lacking: his slides are absolutely atrocious in organisation and in interpretability. He writes down lecture notes as if he is presenting a Masters’ thesis and not teaching a class and assumes you will be able to fill in the blanks. He does have a textbook but nothing he seemed to teach was remotely related to the textbook at all so that didn’t appear to have any relation. Basically, you are at the mercy of his lectures, which are horrendously structured: he basically just jumps around aimlessly (similar to his structuring of the overall class) and doesn’t explain any concepts, he instead just repeats a few examples and expects his students to get it. He also would ask random students about the material in class and it was very evident that his teaching style wasn’t hacking it, since no one understood anything. If you got something wrong he would sometimes make a very sardonic remark like “see no one agrees with you” or something of that nature. His lack of preparation and organisation of classes and lessons also makes it very difficult to study for exams at all. The slides are so barebones you just have to pray he covered everything and even then you’re bound to encounter something that you have covered very little in depth or maybe even not at all (on my second midterm, there was a question about blockchain, which was a topic that wasn’t even mentioned in the lectures and predictably did not show up in the slides either when I checked afterwards). He also gives very little detail as to what is on the exams, preferring to opt with the classic “anything we covered is fair game” trope. Another annoying thing is you hardly ever receive your tests or in class quizzes back, so you have no idea where you’ve gone wrong or where to improve; this also makes it very difficult to study for exams if you don’t have take home quizzes (which fortunately we had quite a few). He also has a tendency to cram material that you literally just learned maybe two days before the exam onto the exam itself: on my first midterm, we literally had an entire section on Sequences worth 30 points (worth 20% of the exam), even though he quite literally only covered Sequences in THE CLASS DIRECTLY BEFORE the exam. His grading is super weird and he seems to mark points off arbitrarily with no rhyme and reason. His grading inconsistencies are compounded by the fact that he has his TA grade assignments (I’m not sure if his TA was grading quizzes, but I know for a fact that she was grading Homework). His TA literally grades things that are objectively right as wrong and when this happened and I talked to him about it, he said he would tell the TA, only to never get back to me on the subject (fortunately, my homework grades were relatively high so I didn’t really care as much). At least his TA actually tells you what you’re doing wrong though (or supposedly did wrong at any rate) because when Dr. Han grades assignments and tests, he literally just marks where you got points taken off with no indication of what you did wrong. On the topic of homework: he assigned coding assignments in them which he never once instructed the class how to do. Literally the only way to do them is to search them up. Lastly, he gives weekly quizzes which he did state in his syllabus he would do. It doesn’t sound too bad except toward the end of the semester, he began giving us daily quizzes with literally no rhyme or reason other than “students are skipping class and are disrespecting me by thinking they can self study” (as if he knew exactly why the students missed classes). His quizzes also, similar to his exams, involved material you learned maybe two days prior (toward the end of the semester when he was giving out daily quizzes, he would literally quiz us over the material we learned THAT day on top of material we learned in previous days). His quizzes were also much more difficult than they should’ve been and exceeded the difficulty of his in class examples. His projects are truly awful and follow the rest of his assignments: they go over material he has hardly or never even cover leaving you to search up how to do most of them. On the topic of projects, he planned 3 projects, but we only got to 2 of them and he didn’t even assign the first until late March, nearly 2 months into the semester. The only positive was that he provided frequent extra credit opportunities. I pray that I won’t ever receive anyone as inept at instruction again in the future at Baylor. As I said before if you’re in Data Science, he is your only option for Discrete. If you get him, my recommendation is to study hard, prepare for exams and random quizzes at a moment's notice, and pray that you can understand the material because neither him, his slides, nor the textbook will help you achieve that goal. A complete waste of a class and this class did not prepare me at all for any future courses in Data Science or Computer Science related fields.  - Grade In Class:B+

Comments:2350 - Dr. Han has a very thick accent so he can be difficult to understand. He also makes this class more difficult than it needs to be, but there are good outside resources that can prepare you for the test. However, I will say that on our first midterm, nobody got an A, and he didn't curve it or anything. He is entertaining and funny, but not the greatest professor. Go to his office hours if you want to be thoroughly entertained.   - Grade In Class:A
