She cares more about her research then about students or class. Do NOT take her!

she is completely NOT helpful. she is also difficult to understand. do not take her unless you don't want to learn and do well.

This is a class in which you will HAVE TO teach yourself. the only help you'll get is from other students. if you want to get close with your text book and get completely frustrated, then this is your professor!(and i got an A)

DO NOT TAKE THIS COURSE WITH HER!!!! NOTHING BUT CONFUSION.

if you like to teach yourself she is best. she just write down everything on blackboard that's what and that's the way how she teaches.i dropped her class.and same advice to you all

shes a horrible teacher...speed notes..doesnt teach or explain anythin...no h/w and her quizes r really easy..i learn from the book not from her..if ure willing to learn on ur own then take her cuz shes easy

Booooooooooooooooooooo. Learn her language before taking this class, then you just might understand what the hell is going on.

SHE IS ABSOLUTELY THE MOST HORRIBLE PROFESSOR!!! If you have her change classes immediately. She is extremely hard to understand and does not explain things well. Absolutely horrible!

She is horrible

I honestly wasn't going to write anything about her because everything in the other comments says it all. Then in class one day she decided to call the entire class illiterate because we argued that she did not teach something that was on a quiz. Anyway, what you can expect is about a quiz each week, not much help from her, her accent is very heavy

This woman is ridiculous. She knows her math, but she is not good at teaching it whatsoever. She also has a very heavy accent, which is hard to understand! DO NOT TAKE HER!

RUDE, RUDE, RUDE!!!!! Extremely unhelpful. Always the first one to leave to avoid questions at all costs. Makes mistakes all the time on the board. Lectures are pointless.

she really knew what she was talking about, just not how to teach the material. went to her for extra help and lets just say never again. On the bright side, you were allowed to retake your quizzes for full credit- that was the only good thing about this class

I do not learn from the lectures; I teach myself from the online homework, which saves my grade. She sits behind a computer and talks; gives very few examples. And when you ask a question she gets annoyed and asks why you don't know the answer even though it's her fault. Only good thing: she gives make up quizzes online.

She is very argumentative and stuck in her ways. Don't bother asking questions because she will just give you an attitude. If you are looking to actually learn, try to take someone else if possible.

Don't take her class. She is very argumentative and nasty to students who ask her questions about the material. She has a heavy accent that bores everyone. Doesn't explain anything well at all. I'm surprised she even has a teaching job lolol

Don't expect her to be that helpful. She doesn't give many good examples, so I had to basically teach myself this semester. Avoid her at all costs!

I've never struggled in math up until this point. She did not present the material in a clear way and was unapproachable, making it hard to ask questions. Her teaching strategy is extremely ineffective and my grade suffered tremendously because of it. Avoid taking her class if you want to get a good grade.

she is the absolute worst. She doesn't teach clearly, her tests are short but very very very difficult and worth a lot. She's jus the worst. Avoid her at all costs. Thank me later.

Brief reasons why her class is difficult. 1. she goes through the material too fast 2. She skips steps in her examples 3. She's often argumentative when you ask questions 4. She does not know how to explain the material simply Only take her class if you are willing to teach yourself, through tutoring or Youtube.

Professor Choi is not a very good teacher. Her accent makes it a bit hard to understand what she is saying and she moves very fast. When you ask a question she might Not even answer it . Also, she is a very tough grader. For example, if the answer is 4 and you put 3.98 she will mak it wrong because you did not round properly.

This professor developes an attitude when asked questions and is generraly unaprochable. Students ignore her during lecture because they end up more confused than they were originally. Most of the time students end up teaching themselves the material.

I taught myself Calculus last semester because she CAN'T teach. I spent hours each week just trying to keep up with the material. Her problem is that she zooms through lectures, does not explain material in an understandable manner, and shames students if they ask a "stupid question". Save yourself hours of unnecessary work and stress: AVOID her.

I took Choi for Calc 1 Fall 2018 and let me tell you, it the worst decision EVER. She is very combative when you try and ask for help and always resorts to the phrase "you should know this". Goes way too fast!!!! We didn't have one passing average exam/quiz. If you do take her, make sure to do the HW and know how to do each problem on it by heart.

She does not allow makeup's for any of her quizzes does not matter the circumstances. She might drop the grade for you if there is a reasonable explanation. You definitely need to understand the subject beforehand or else you will be lost.

Does not really teach you what you're supposed to do. Assumes that you already know everything and should have no problem with it, does not really explain anything, and expects that after she does a problem (without explaining anything) that you should be able to do ones that are much harder.

She gives two question quizzes once a week and doses not allow makeups or extra credit. If you do not understand the curriculum she won't be much help either. I was getting tutored and they said I knew my stuff very well, but not well enough for her course. I would try to steer away from her if you have never taken the subject she is "teaching."

I took her over the summer and she literally doesn't teach anything. She is a horrible professor and has a horrible attitude. Only wants things done her way. Does not give makeups and gives you a lot of homework and two question quizzes weekly. The exams are worded weird so unless you have a good foundation in algebra/ precalculus, don't take her.

I've only had her for a couple days so far in the summer and she is the worst professor I have ever had. Don't be fooled by previous comments because she is terrible. I was expecting to learn in the class, but she barely even teaches and you can barely understand her because of her accent. The university never should've hired this woman.

Horrendous. Don't take if you know what is good for you. Had to withdraw from the class because I couldn't risk an F on my transcript. Failed the first quiz because what she taught in class wasn't on the quiz. If you're not good at math take a different professor. This professor literally made me switch my major, that's how bad she is.

Professor Choi made me not like math anymore. I took precalculus during my senior year of high school and I retook it with Choi. She does not know how to explain and when she explains she does not use numbers in her problems. Do not take her class

Her workload is not the worse... However, when it comes to teaching us Calculus it is much more difficult than when I read the textbook. Overall, if you can teach yourself through a textbook then go ahead and take the class. If you struggle teaching yourself through the textbook then I don't recommend her class because it will reflect on your grade

She doesn't go over the material in depth. She kind of just lightly explains in and expects you to deeply understand it from only one or two easy examples. The questions on the tests and quizz are nothing like what you were going over. I got a 100% on all of the HWs and the quiz reviews but did poorly on every quiz because the material is different

Do not recommend taking her

Unfortunately, Professor Choi lives up to the poor reviews on this site. I politely emailed her about an unfair grade I received and was shocked at how defensive and sour her response was. My grade was never resolved. She has a habit of adding material to quizzes and exams she has not gone over in class, which I find frustrating. Beware.

Quite possibly the worst professor I've ever had at Montclair. The material and concepts were explained very poorly. Because of this, I turned to online tutorials in order to learn the material. Terrible at communication, and extremely rude whenever you did try and reach out to her. Would never wish this class on anyone. Stay away!

Wow. I might just say that this professor, is in fact, the worst professor to ever exist at all Universities across the countries. Applied precalculus was impossible to learn with her as a professor. Very intimidating and if you asked for help, she got mad. I had to switch my major because of this professor. The university needs to review her asap

This was the first class I have had to drop, it was very hard to understand and she went through the material very fast without any recaps. I do not recommend taking her unless you have to, just expect to work hard and teach yourself mostly.

Awful awful awful awful awful. Not just her fault, the entire Math department of Montclair is a horrible joke. Every higher-up who runs this department needs to be fired immediately. These classes are structured terribly and taught by incompetent people. I had to drop this god-forsaken class because of how absurdly ridiculous the teaching was.

Had to withdrawal from this class because it was impossible. She cannot teach for the life of her. Would not wish this class on my worst enemy. I'd rather get hit by a car than ever take her again.

She was not supportive or helpful. If you had a question, she wouldn't answer it and would say to ask classmates (but I already had and no one knew what to do). Her grading was all over the place too and very strict. This class was such a mistake to take and I would recommend anyone who consider taking a class with her run the other way.

worst professor ever. DO NOT TAKE HER

I took her for AMAT220. She was absolutely awful. She didn't care about how you did I frequently went to her office hours and she was very rude to me. Please avoid taking her and take Calc II instead she was not clear in lectures whatsoever and never explained what you did wrong. She gives you one extra credit opportunity that does help your grade.

I took her for AMAT220. Worst professor I have ever taken. She doesn't care about her student and she was very rude to me when I told her that my grade is unfair. She gives you one extra credit opportunity that barely helps your grade and is the stupidest project ever. AVOID TAKING HER AT ALL COSTS.

Terrible professor. It's impossible to understand what she is saying or understand how she teaches the class. She is not approachable and has a tendency to make mistakes in grading the quizzes and tests. Avoid her at all costs. Worst professor ever.

Im taking Applied Calculus B. I'm ngl, don't take this professor. Cannot teach nor is helpful. Don't know my final grade yet, but I've never struggled with a math class until having this professor and my entire class is failing….That should tell you everything you need to know.
