If you took AP statistics or even just regular statistics during your high school year, then here is a free letter grade "A". He gave a lot of extra credits questions on the quizzes. Homework is little tedious and sometimes hard to do. But you will be fine.

Sung really cares about your success when you work with him. He will often do out of hours work and specialize on helping you in the class if you need it.

I liked Sung Chan's direct teaching style. He will be available for office hours quite a bit if you have any problems. He does go pretty hard on homework and daily quizzes but that much repetition makes the exams a lot easier.

Professor sung was really amazing. For math 3070 everyday you have a quiz and before lecture starts he gives you a quiz review and then at the end of the class the actual quiz which is exactly like the review with different numbers. His exams are super easy, if you do well on the quizzes then his exams won't be difficult at all. learned a lot!!

Prof Choi was a pretty solid teacher. Hes pretty understanding when it comes to making up quizzes, extending hw deadlines, and offering help outside of class. The only things that would improve this class are not having a quiz every time we have class and it wouldve been nice to have more time for test reviews.

He is one of the nicest professors I've ever had. He made the lectures fun and always did a review exactly like the daily quiz we'd have everyday. Study guides for each test are extremely helpful, and he did everything he could to help his students out at the end of the course (dropping extra quizzes, redoing the curve on old tests, bonus points).

He really cares about students and generous to students. He teach student well. if you want to study that course accurately. you will absolutely love this course!

I liked his class, if you took math in high school and did well than theres nothing to worry about. He reviews everything clearly and lets you have a sheet of notes for tests. Would recommend!

This is definitely a class that can be scary the first few weeks but if you keep going at it, it'll become easier. His teaching is a little difficult to understand but as long as you use your resources, whether it be the TA's or taking to Prof. Choi, they'll work with you. He was very accommodating and did his best to help us pass the class.

This is definitely a class that can be scary the first few weeks but if you keep going at it, it'll become easier.

I was sick and missed an entire week of class and Sung Chan Choi was very helpful. He sent me all quizzes (they are daily) and gave me extensions on quizzes, hw, and a lab that was due that week. You have to go to class to get the quiz, so make sure you're not regularly missing class. His homeworks are pretty long, but he is very accommodating

He gets gets of bad rap but I made a leap of faith and I dont regret it. The notes were set up so you wouldn't waste your time writing proofs. There are quizzes but they are take home and often very similar to the examples covered in class. The labs were REALLY tough on your own and I often didn't do them. He is pretty cool, the class is tough

Professor Choi is an incredibly caring professor. He does a fantastic job making very difficult subjects manageable. Is very well organized, and tells you exactly what will be on the tests. He teaches some very difficult subjects which is why some people are angry about his classe. If you don't want to work then you shouldn't take high-level math.

Choi was awesome! He was accomodating and when students complained about him being too quiet, he bought a portable mic and speaker. Even though sometimes he's hard to understand, sit in the front and you'll be fine. Also provided his own notes, which made studying and following along a lot easier. Homework is straightforward, tests aren't too bad.

Prof. Choi is a fantastic teacher. He really cares about his students and takes time our of his office hours and personal life to help his students with any help they need. He responds to emails even when it is very late. I think it is admirable that he is such a great teacher despite having a hard time speaking english.

Incredibly caring and competent prof. He's so helpful in many ways:responds to emails quickly, available outside of class, takes extra time from his office hours to help if struggling. People think he is very strict, but he is very lenient. Despite having a language barrier, he works very hard and makes his material relevant and easy to understand.

An absolutely amazing professor. You might think that daily quizzes are rough, but they are not difficult and do wonders to reinforce the material. He walks you through a review sheet that is almost exactly the same at the beginning of class. He never takes it for granted you know something and reiterates a lot. Best math teacher I've ever had.

He is pretty relaxed and he tries to help the students hear him better with a mic.

Daily graded quizzes, but they are the exact problems you'll get on tests. His tests are also very easy. Amount of problems on weekly homework could be dialed down a bit, but otherwise a great teacher.

(There were no options to choose MATH 1220 on the source code so I had to select 1210). I took Calc 2 from him. He's a great, caring, and generous professor, and exams were primarily based on quizzes. I would definitely take other math courses with him next time. Just beware of attendance and daily quizzes.

The structure of this class is one of the best I've ever had. He had clear lecture notes that he followed along with daily quizzes and weekly homework. The daily quizzes were short and typically not too difficult and they truly reinforced what we were currently learning. The homework was not too much and help was available if needed.

Professor Choi was a great teacher who had a very straightforward setup for the class. With quizzes every single class period, it's really important not to miss class as much as you can, but I can tell you right now those quizzes help so much. I did little studying for this course and relied mainly on the quizzes to learn, I highly recommend him.

Well organized class. Lectures were easy to follow, he had very clear explanations on the subject. He has quizzes everyday but 8 drops so it's okay to miss a class then and there. As long as you do good on the quizzes and use them to study, you can pass his tests. In this class I was able to genuinely learn the material and do good on exams.

Sungchan is a wonderful professor and probably my favorite math professor I have had at the U. There is a quiz each class but he does a review that is nearly identical to the quiz each day at the start of class. He genuinely cares about his students and is always an open door for questions. Be respectful and responsible and you will do fine!

Took eng calc 2 with him, hardest class I've taken with an insane amount of material to cover but he was a great teacher and really got me to work and learn a lot. If I would've taken this class under anyone else I likely would've failed

Sung Chan is a very good professor and does genuinely do his best for his students. 5080 is notoriously difficult, a fact which isn't helped by the textbook. Sung Chan distilled this textbook into something more readable and essentially rewrote the textbook, correcting its flaws. Prepare for daily quizzes, homeworks require some time and thought.

Sung Chan is difficult to understand but his handwriting isn't illegible. He really wants to see his students succeed!! I went to his office hours every week and we formed a really good bond. I took this class a year ago and everytime I see him still, he still says hi and we chat. He wrote a good reference letter for me.

3220 is a HARD class. Most topics will be confusing at some point. I took this class in Fall 2023. There were daily quizzes assigned every day of class, as well as homework every week/biweekly sometimes. As for exams, well the only reason I got a B is because how forgiving he grades exams. He speaks quietly and with an accent. Good lecture layouts.

Super funny Does a lot of examples making it easy to learn.

Teaches well, short quizzes every lecture but they are due 11:59pm day of. Homework is a little lengthy, assigned once a week. He does care about his students, goes based off the textbook and never waste time.

Daily quizzes but they truly help you learn. It's obvious he truly cares about his students' learning and he does his best to assist each student to help them succeed. He will make sure that everyone gets the concept before moving on. One of the only classes that I truly learned a lot and felt confident about. Definitely a top-tier professor.

Daily quizzes are kind of a hassle but they don't take much time. Seems scary initially but is actually pretty nice. Exams are copies of his quizzes (90% avg). Straightforward and pretty easy, especially compared to other professors.

Took his class for Engi. Calc 2 and Diff Eq. He is an incredibly fair but tough teacher. He will never testor give you hw on something he hasn't taught you on. Attedance is mandatory but tbh his class is the only one I look forward to.

One of the best professors I have every had in math. Made things clear, lectures notes you can look back at are very well written out. Many example problems. We did have daily quizzes and a handful of homework but the quizzes are short and based on that day's problems. Honestly a very good way to practice, exams were similar difficulty to quizzes!

I did the best I ever have in any math class as Sung Choi as my 2250 teacher. He had daily quizes that helped a ton to get ready for the exams. Homework and a lab every week which also helped to get ready for the exams. He is hard to understand but if you go to the tutoring center, you will easliy get a good grade.

I learned a ton in this class. Prof. Choi was very clear and detailed in the way he explained things and was thorough about showing the steps to solve each problem. His quizzes and note sheets helped reinforce what we learned in class, the exams were always based directly off of them. He was always nice and pleasant to students. Highly recommend!

It can be really hard to understand him at times. Mr. Choi does give out daily quizzes, so attendance matters, that are due the next day, but most of the problems are pulled out from the lectures. Exams are very similar to the quizzes. Mr. Choi is a great professor though, just be weary by the quizzes, they can be challenging at times.

His teaching style made complex mathematical concepts easy to understand. I really liked the class structure, and he genuinely cares about his students. He comes well-prepared for each session, and after taking his class, you can't help but grasp math better. Highly recommend!

Attendance isn't graded, but you have to be in class to receive the quiz + lots of homework. Other than that, his teaching style is great and he explains the content in a very understandable and simple way. Exams are graded very leniently and are similar to the daily quizzes. Very funny and down-to-earth professor.

I took his Calc 3 in the summer. He is an amazing and hilarious man, and he teaches you the important things.

Choi is the goat. He does give a lot of hw. He also gives daily quizzes which can be annoying but if you do them you will easily pass the class. Attendance is required because you need to come to class to get the quiz and they're part of your grade. Tests are easy and basically reprints of the questions on the quizzes. The hw is very tedious.

Dude lectures very concisely and the tests are the same questions from the daily quizzes.

while the material could be tough, sung choi was able to make it all so easy to understand

Lots of quizzes, but Exams are straightforward and not too hard. Attendance is basically mandatory but he taught the material extremely well.

He's a king. There are daily quizzes that you have to get in class, but they really help understand the material. The quizzes are like the tests and he genuinely wants you to understand. Love him!

Vector Calculus and PDEs for engineers. The daily quizzes are annoying and time consuming, but they force you to learn. Basically it's a lot of content for one class, but he teaches it pretty well. Super organized guy.

Sung Chan was good at pushing understanding of the material. He would take time in lectures to show some examples and push understanding. Beware of daily quizzes, which arent that difficult if you pay attention in class, as they make up a good chunk of your grade. Exams were easier than hw, which could be tedious. He offered extra credit in exams.

Choi is the goat, yes he gives you daily quizzes but they aren't hard especially if you do them right after class.

Took his summer Calc 3. Definitely a language barrier but he will answer all questions asked. Not a bad lecturer and he gives you up to 10 points of extra credit on every test so its pretty hard to fail... Exams are very similar to quizzes but the homework can be difficult at times.

Professor connects concepts well to previous knowledge to make it easier and faster to learn. He answers questions very thoroughly if you go up to him during break or after class. Homework can be a lot but exams are easy to study for.

He's probably the best math professor I had despite the low reviews. His lecture notes were helpful studying for quizzes. His tests are VERY SIMILAR to quiz questions and we get a two sided note sheet. Homework was busy work and annoying. Hes a very straight to the point and blunt man but unintentionally funny. Some people can't handle tough love

I got 102% and loved this class, it was so hard though. I think his class structure makes the workload unnecessarily excessive, however it helped me learn the material better than ever. Daily quizzes were hard to juggle with my disability, but if you put the time in this class will set you up to learn well.

Take any math class you can with him. You will not regret it

Such a great professor, gives you points wherever he can (dropping lowest 6 quiz grades, lowest 3 hw assignments, and lowest midterm grade), and gives amazing notes for how to do things, however he does do a quiz every time you are in class. The quizzes are fairly easy as long as you paid attention in lecture.

Dr. Choi is a very tough professor, and is big on attendance. However, he offers a lot of extra credit during exams. The daily quizzes are actually very helpful to study from and overall his lecturing style is very clear and concise. Overall I would definitely recommend taking a math class with Dr. Choi.

Professor Choi was good, You have to go to class because of daily quizes, however these quizes are pretty easy and often are taken home. Exams are honestly easy and he gives plenty of resoruces. GO TO CLASS. Also drops lowest 6 quzies and homeworks and lowest exam score. Overall pretty easy class. Hard to understnad but if you listen your fine.

I only say lots of homework because he gives daily take home quizzes but they're always related to that day's lecture. His notes are great and the tests directly mirror the quizzes. Easy way to study and he wants you to pass.

Love this guy! Comes across a little rude at first but ends up being one of the best professors. Daily quizzes are a little annoying but super helpful in the long run since he bases exam questions off them. Makes tough concepts easy to understand through lots of example problems. Difficult course but very easy to succeed if you put in the work.

If you attend lecture every day and do the quizzes, you'll easily pass. Teaches the material concisely with good examples. Exams are just the quizzes with different numbers. Hard to understand his English sometimes and doesn't answer questions well, so just look those up later. ATTENDANCE IS ESSENTIAL. Funny guy too, first time I've liked math.

I really enjoyed his class! If you come to every class and pay attention during his lectures then it is an easy A. Even thought English isn't his first language, his lessons are really easy to follow and he is good at explaining! He is also really funny and his class was very chill. Also exams are EXACTLY like the quizzes!

Be prepared for a heavy workload, but the path to an A is very clear. While the weekly homework feels like busy work, the daily quizzes are actually the most important part of the class because they mirror the exams exactly. The lectures also align perfectly with the exams. If you show up every day and master the quizzes, you will pass easily.
