HORRIBLE! Cant understand ANYTHING.

sucks

worse math teacher i have ever had. he cant teach and cant even do the problems correctly

Can't teach. Foreign accent makes him difficult to follow. Races through material. Constantly makes computational errors. Tests are completely unpredictable. Irritable, annoying, and sarcastic. Worst math teacher I've ever had.

by far the worst math teacher i have ever had, i spent this semester teaching myself. his job is to make things clear not to confuse things. after every class i came out more confuse than i went in. DO NOT TAKE CHOI!

Awful...just awful...

If you were to get an A in anyone elses class expect to get a C. He is impossible and I ended up teaching the course to myself

Terrible, just terrible. Don't even think about taking a class with Choi.

I did good on the Math SAT's and am generally good in math, but this guy takes something I already know and makes it so confusing that it is impossible to sort it out. He makes so many mistakes on the board, he should really go back to school before confusing people. Avoid if possible.

save yourself!!! do not take this man as your teacher!!!

Choi is the most confusing and lousy prof ever. He should find another career, maybe liquor store owner since he seems to make a lot of alcohol related analogies (his way to "relate"). DO NOT TAKE. I regret taking him severely. If you read this Choi, please quit teaching. do everyone a favor.

horrible teacher..an ok guy, but absolutely horrible..cant understand a lick of his language..

NOT A GOOD TEACHER> DO NOT TAKE HIS CLASS.

You cant even understand what hes saying. He basically has you teach yourself the material. He gives you 100's of handouts and expects you to do alot of homework and online work. I would not reccomend his class.

Prof. Choi can be a bit difficult to get a hold of. I took his class online, so I don't know if it is different otherwise. The class itself wasn't hard, but I'm glad it wasn't because I basically had to teach the entire thing to myself.

I found him to be very unclear with direction's causing me to fall behind and have to withdraw from the class. If you are taking an online course for the first time He does not help you much with assignments. He seems very sarcastic with his responses to emails which i found to be disrespectful.

Very hard to understand what he says. he gets frustrated with students very easily, and can be rude at times for no reason. He seems very sarcastic with his responses to emails which i found to be disrespectful. Unless you are a math wiz, i suggesst another teacher!

makes fun of people during class, is not encouraging, tells people it's normal to fail and encourages people to withdrawl the class.

Horrible teacher! If you struggle in math DO NOT take his course. Very hard to understand. If you have a problem with a question, forget about asking him. He is terrible! Worst professor I have ever had!

He made it very hard to pass this class. Put in min effort but expected beyond max effort from students.This class is 100% selftaught and the exams were too hard.The final exam guidance was to know how to do the 161 hw problems assigned.I LOVE math and this class was still a huge challenge.Do not take him online if you're looking for a fair course.

The WORST professor I have ever had. If you're not as good in math, like myself, then do not take any classes he teaches. He goes so fast in the lectures and if you get behind, it's your problem and he has limited sources to help you and give extra help. Spare yourself the stress and take a different class.

Guy tries to be nice by offering his class food or coffee. He uses that as a replacement for the time and effort he should be putting into lectures and grading. He marked answers wrong on a test when they were clearly correct. Hard to understand him sometimes and was a waste of time to show up to lectures. He would go over book problems on a slide.

If you're not doing well in math don't take this dude. He's a nice guy but sucks at teaching. Every time I needed extra help he gave me nothing. I went to the support center and in the 10 minutes there I understood more than in one of his class lectures. Totally sucks.

Goes over material too quickly in class and does not take the time to explain what's going on. If you miss even one class you are so behind and it's impossible to catch up. Do not take him. I received 100% on my homework but struggled with the tests and finals. Failed me by 2 points. Horrible teacher.

Professor Choi was one of the worst teachers I've ever had. he gave terrible lectures, and gave up on them half way through. His "lectures" were him reading directly, poorly from the text. When he stopped giving lectures he would expect us to figure the topics out on our own. I hate to say this, but there was a genuine language barrier. STAY AWAY!!

Yikes. Line up your textbook and your tutors because you'll likely need them. The thick accent makes learning a difficult topic even more stressful, and essentially you'll be teaching yourself here. He cares but explains everything quickly and gives lots of ungraded homework. Tests can be pretty difficult and are worth the majority of your grade.

I took Choi for Calc1. He's a nice guy, but gives a lot of homework from the textbook, he lectures quickly straight from the textbook w/o really explaining the material. If you want to actually learn in this class, you have to teach yourself. His accent is pretty thick & there is a genuine language barrier. I wouldn't take a class with him again :/

Avoid if possible. Often comes to lectures unprepared, which in turn results in disorganization, dissonance and inadequate explanation; makes concepts far more complicated than they need to be. Definite language barrier, challenging to understand at times. Grading policy left unclear, however, seems rigorous and partial credit is never awarded.

Horrible professor, does not care for his students at all and gives low effort lectures. Basically have to teach yourself. Avoid at all costs

Hes the worst Professor I have ever meet . He is so mean and careless about students achievement. He needs training on teaching !

Honestly I had this professor and I really wish I didn’t, doesn’t care about how you do just said “ I get paid to come here and read off the board” does not care about teaching his students and trying to community with this man through email just good luck

Absolutely horrific. I took his online course and was just thrown a bunch of homework every week with no

No explanation for lectures. Only gives PowerPoints without any clear description as to what is actually going on. It takes a long time to respond and does not seem willing to work with you.

The teaching curiculime in the course was not good AT ALL. DON'T RECOMMEND.

Professor Choi is the MOST annoying professor at Rvcc. not only does he teach off of slides, his explanations are horrible and genuinely hard to understand with his accent (sometimes). DO NOT take him unless you are ready to go to office hours or the tutoring center 50% of your time in the semester. WARNING: DO NOT TAKE HIM.

STAY AWAYYYY IM TRYING TO SAVE YOU MONEY AND TIME BRO IS CHEEKS AT TEACHIng and should looked into I swear. Homework's and lessons the hours to do even you already know some of the stuff. Take another teacher it will be your savior I am telling you. Sadly I wasted my time and money
