why is this class teaching... he doesn't even know how to use a graphing calculator... don't even know how he got hired in the school... if u noticed he has his passport picture on the website.. i mean comon now!!!

Very hard to understand. Class is way to hard. Big waste of my time. I just stoped going to class. This guy needs to slow down on the content and be more clear. If you take him you will have a hard time.

dropped his class because he was so incredibly hard to understand--DO NOT TAKE HIM---jumps around a lot, unstructured lectures

STOP RIGHT THERE !!!!! YoU do not wanna take his class... I got a "D" in his class even though i got 45/50 in all my tests, did my homework and went to class every ****in day of class !!! HE SUCKS!! NO DOUBT ABOUT HIM!!! BETTER OFF TEACHING PING

can not understand a word this guy is saying, i think that clear speech should be required for teaching a subject to people who are trying to learn. One of the worst math classes I have ever had

He wasn't clear in his lectures and did not go over his tests after you take them. Tests were really hard too.

Wowwww... this class is "elementary geometry" and he makes it hardeer than it seems. His grading is TOO HARSH and when you try to discuss it with him--u dont get any partial credit!!! I've never had a math teacher who is so UNFAIR

cant understand this guys accent. gives toooooooo much HOMEWORK! and the tests r so ridiculous...they never ever cover wat u learn in classs...he has 1,000 proofs on it and 1 equation. everyone in my class has C's and D's. he's the worst teacher ive ever taken

want to pay for an F? TAKE HIS CLASS!

horrible!! cannot understand a freaking word that he says!!no matter what I did I still got an F!! dont take!!

After taking Luong I think I have found the rudest professor I have ever had! He would say the book is wrong like every class. Did not know what he was talking about at all. When I went to the TLC and showed them my notes they wanted to know what he was teaching because it was all wrong. The class started with about 40 and ended with 10.

He is the worst teacher ive had he pronounces everything wrong and its hard to understand him , he teaches really weird too , you dont learn anything you have to teach yourself

This professor teaches in a very simple manner yet does everything he can do confuse you on the exams. I recommend that anyone who takes him be a math or physics major because if not you will fail. He is very difficult, and cares little for his students.

worst math class experience of my life, act friendly, finds every possible way to stump you on the exam. Makes you believe the test will not be as difficult and then throws in a bunch of trig. Do not take him!

Can hardly believe this guy still has a job?! hands down the worst teacher ive ever had. he does not prepare for lecture and spends most of the class talikng to himself at the board! not to mention he yells at us and calls us stupid often!! "many of you going to fail my test!" he boasts as he gives his tests that are full of things we never learn!!

techer is horrible. he says less than half pass his class... true! he barely speaks english, doesnt explain how to solve the problems on notes, and gives the absolute hardest problems and expects u to know them. honestly, take another teacher by all means.

I took this class YEARS ago and I cannot believe he is still teaching here. I LOVE math and I've always done really well in all my math classes, but he is the WORST teacher I've ever had. He is difficult to understand and he is not helpful at all when you have a questions. I would avoid his class if possible!

I don't know how to start this without feeling extremely angry...but, This guy is by the far the worst teacher i've ever had; he does NOT deserve to be even remotely close to academics. His structure is more confusing than helpful, and just trying to figure out what he's saying is a challenge. Grades very,very hard on all assignments,test-h.w.

Worst. Class. Ever. Can be condescending and is very unorganized when it comes to lectures and he never finishes a problem. He will get halfway through it, say you don't get it and then erase it. No matter what I never got full credit for hw even when I asked him about it. Tests=ridiculous. The only thing that saved me were his 10 pt quizzes.

All around terrible teacher. Tests are ridiculously hard because he doesn't teach the correct material. Managed to maintain an A throughout entire course until the final by teaching myself. Do not use any of his methods. Stick to the book and you should be fine. Figured out if you disregard everything he says and you teach yourself you do better.

Very very rude to his students. He always insults us by saying we belong in Math 070 implying that Math 070 students are unintelligent. Does not know how to teach so as long as you learn from the book and not from him and his lectures you should be fine. Ended with an 89 because of material he didn't bother to teach but he put on final. Work Hard!!

Avoid. You don't have to show up to the classes, except I would go when he talks about changing variables. Go to the review days, as they will generally increase your test grade by a letter. Make sure to read the book because Le explains poorly. He has good intentions of challenging the student body, but bad execution. This was the worst math class

I checked ratemyprofessor before enrolling in his course but he was the only one available. I am an A student especially when it comes to math, but even with near perfect attendance, over 20 hours a week studying and watching youtube videos explain the lessons, I did not pass the class. Homework and review are nothing like the tests. Avoid!

I sat through Le's class for a week and another teacher's for a week (to crash), seeing the difference in teaching styles it was quick to see that i would have struggled very much if I had chosen him over the other teacher. when i asked questions, more questions arose, his explanation to my confusion was not helpful at all and further confused me

Don't take this dude for calc! Hes very messy with his penmanship and not only that his accent is horrible! Studied on my own the whole time. Did every extra credit and homework. He end up giving me a D+. Wth man before I took the final I had a C-. Watchout for his test hes a harsh grader one tiny mistake -10 pts out of 12. Take my advice and avoid

He is awful do not take!! I'm very good in calc but he just doesn't teach right I've spent most of the semester depending on my prior knowledge of calc but it doesn't help with him, he's a tough grader and he has tough tests beware

Do not take unless you are one of those students who can be self taught. He uses his own notes for each section but it's all straight from the book. He would get almost every problem wrong so class would have to correct but it was very confusing. Don't explain well. Just horrible. Nice guy though, but not a great teacher.

Worst math professor ever.. Makes fun of his students for not knowing the material. Very rude and discouraging. Don't take him.

Not recommended for first time Calc students. Provides poor feedback.

He talks very fast and goes off tangent that which makes it very difficult to decipher what information is necessary to know and what is just fluff. Often times he breezes through steps with no decipherable explanation. He overly explains the simplistic things yet barely explains the important information.

Very strong Chinese accent that makes it hard to understand him. He would go off and talk to himself about irrelevant topics. Horrible teacher, I love math but he just made me hate it. I do NOT recommend taking him for a math class.

Absolutely horrible teacher. Unbearably rude and unhelpful. Took my passion for Math and stomped on it. He is a miserable teacher to be around and 100% unhelpful in every way. STAY AWAY FROM HIM OR ANY OF HIS CLASSES

Halfway through the semester I gave up on learning anything from him and self-taught myself everything from the book, which is probably the only reason I was able to get a B. This class ruined my 4.0. He doesn't allow a cheat sheet on any tests and expects you to memorize every formula. You have classwork to turn in, so you can't miss class.

I will be honest, professor Le does not explain the material well at all. You have to basically teach yourself through the book. He expects you to know it all so when he explains a problem to you it's not clear at all. He sometimes doesn't know how to do the problem himself! Basically, i recommend taking another class other than him!

His communication skills are so poor that it's pointless. He'd start on one topic and forget what he was doing midsentence and move on to a different example. He didn't know how to do half of the problems and mainly read from the book.

Please don't take his class, find another teacher. I usually don't like to rip on professors, but this guy deserves it. Acts surprised when students haven't mastered material taught 5 minutes prior. Often pauses and stares at his own math in confusion and his problems on exam much more complicated than what he taught in class.

My biggest regret this semester is not listening to the warnings about professor Le. He's very mean, doesn't like to answer questions, often talks down to students and his lectures are all over the place. Good luck actually learning anything from this guy. A real disgrace to COC!

Maybe it's my high standards of math teachers, but this guy was terrible... If you don't understand something don't rely on him to explain it. He tries to brush you off, you're the least of his problems. I still remember in class, he refused to go over an example because we did one that was similar to it! Do yourself a favor and don't take him.

Take another professor if possible. He expects you to show explicit work on everything and if you don't, he will deduct points. He is somewhat disrespectful to students with racial remarks. Also, his structure is more confusing than helpful, and just trying to figure out what he's saying is a challenge.

Worst math professor I ever had! He makes fun of his students for not knowing the material. He doesn't teach well and his tests and quizzes are much harder than the homework he assigns. Also, he is very picky to a stupid extent.

Avoid his class at all costs!!! Even if you need this course take something else. Just save your GPA and your dignity

He often graded our homework wrong and we would have to show him what the true right answers were. When it comes to lectures, he is all over the place. He sometimes doesn't know how to do the problem himself!

This class was ridiculous. Professor Le was hardly helpful and extremely rude at times. He made fun of 2 kids in our class for not knowing the answer to his question, and said that college probably isn't for them. His jokes are lame and his & reviews are just him listing to bunch of stuff and not clarifying anything.

The class environment can be very discouraging. There were moments during class where no one understood the section he lectured on, yet he STILL expects us to know material & turn in work at the end of class. I was in the TLC literally every day. I had to teach myself, along with the help of the awesome tutors in the TLC.

Horrible teacher. Blows thru material like it's the end of the world. Doesn't slow down no matter how many students ask him to. Almost any question you ask is met with a reaction that says, "that's the stupidest question I've ever heard" (happened to a lot of students in our class, not just me). You practically have to beg for help.

Mean guy. Would not meet to discuss a question. Picked on people instead of taught them better. Went into the class loving the topic and began to hate it after.

I have no words to describe her. I spent a lot of my time in the TLC getting help because he does not teach very well. The homework is nothing like the exams; I almost felt that it was unnecessary to do the homework. He's very rude and doesn't like to answer questions.

His lectures were hard for me because in the middle of teaching he will break into a bunch of nonsense and then lose his place. He sometimes messes up while he is explaining a problem. You will have to teach yourself. He does offer study sessions where you go over test questions which can be helpful.

AWFUL class! I have always been a strong math student, but he has made math too complicated. He can barely finish a problem on the board without making mistakes. He is not helpful at all and gets aggravated when a student asks questions. If you are not good at teaching yourself DO NOT TAKE THIS CLASS!

This class was awful. He will make you feel stupid for asking questions in class and then ask why you are in the class if you don't know the answer to the question. When explaining or teaching he skips steps and does them in his head so if you are a visual or step by step learner he completely loses you. would never recommend to anyone

The worst teacher I have ever had! Never explains anything, never helps, never answers questions, and he is extremely rude! He says he cares about the students, but what it really seems like is that he lives to give students a hard time and kiss up to the administration. Lots of HW, hard tests, and horribly ridiculous grader!

I do not know how to start to describe this teacher. Hhe is horrible, rude, disrespectful. He doesn't teach anything. He expects you to know everything about math, or he would make you look stupid. Simply he is the worst teacher I have ever had in my life, avoid taking his class. If you don't believe me try to take him class to see him closely

By far the worst professor I've had at COC. Doesn't care about his students, nor does he teach, it rather seems like he is using lecture time to brag about how well he knows math himself. There is no doubt that he is an intelligent man, very well-versed in Math, however it is to little help when he doesn't even attempt transfer that knowledge.

He is a terrible person above all. Very condescending towards students. He will confuse you even if you know your math. Worst teacher I've encounter so far. Don't take him, there are far better teachers than him that actually care for their job and want to give knowledge to students

Aside from having a generally negative disposition towards his students, he assumes you already know algebra. I remember asking him a question in class and feeling ridiculed for it because we sat in silence until, after a long awkward pause he finally decided to explain it. His methods are unclear, test are hard and he talks down on students

He is the worst Math teacher I have ever had. Do not take his class, I am warning you. The guy just doesn't know how to teach and his tests are really hard.

Dont even think about taking his class unless you are willing to spend almost all of your free time studying outside of class. Lectures rarely made sense, the tutors in the TLC could teach you what he attempts to in half the amount of time. Grading is extremely harsh, BUT he does offer a lot of extra credit, probably the only reason why I got an A

Literally so bad at teaching. Doesnt explain and just does the work. He expects you to understand everything. Hes also not good at English.

Trust me, Just dont take his class

Do not take this class unless youre willing to teach yourself every lesson and end with a B. This professor to be very inconsiderate of his students. As a student who always takes notes and studies endlessly, he would tell us after each exam about the Calc 2 problems he put on our exams. Hence, why every student would not pass his exams.

If I could give him a negative review, I would, because he should not be a professor. He is an extremely harsh grader and takes off points at every possible opportunity. He makes so many mistakes during lecture and students frequently correct his powerpoint. I wish I took another professor because he is easily the worst professor I have ever had.

doesn' do computers. offers no notes online or reviews. VERY!!! thick Chinese accent. He jokes but he is not in your court when it comes to class he has you vs me mentality. It almost scares me to see how he treats students that need genuine help because he blows you off if you're behind and he can be outright aggressive at times if u ask 4 help.

As the previous reviews indicated he is passive aggressive and has a me vs you mentality. He frequently makes mistakes and gets mad when students correct him. His tests do not reflect what he teaches during the lecture nor whats assigned as homework. If you do take the class make sure you are extremely detailed on the tests, or he will take points

Professor cares about the students and wants everyone to pass in order to make himself look better. Only good thing is he gives extra credit through the HW. DONT take his class at all looking for an A. I am in Math 104 and have friends who are in Calc 3 saying he is teaching material that belongs in their class along with the other Calc classes.

Professor Le is very very unorganized, his class relies almost entirely on the old textbooks of his choice for homework and most of the learning material as his lectures are barebones and not available online so if you miss something during the lecture you're screwed. Only take this class if you're prepared to teach yourself the entire course.

Dont take this Professor, hes a living nightmare...

Nice, smart man but this professor was a really bad lecturer because he goes super fast and honestly it is sometimes hard to understand what he says. Inconsistent, tough grader on tests and quizzes. I got a B in the class even though I averaged a D on the exams and quizzes . Turn in HW and Pretests to bump up the grade he calculates with the curve

Openly brags that almost half of his students fail his class/exams, very hard to understand his writing and accent, and doesn't even record lectures which sucks since he goes through the material pretty fast.

Does not answer questions well and will insult you in the process, then wonders why no one wants to participate. Loves calling students lazy but doesn't give feedback when grading, so points off seem arbitrary. Apparently complaints are common but no one cares. They'll help you get out of the class though. Be ready to teach yourself.

blaming the students for having bad grades and creating a negative atmosphere for the class. please DO NOT take his class for your own good.

one of the worst professors I've ever had. gives attitude when you ask a question, then complains when no one participates. you're better off learning off of youtube videos tbh. gives partial credit if you show work on exams but doesn't explain why he took off points. Avoid at all costs!

So unprofessional that they were at least 5, and at most 20 minutes late to every lecture. Was not competent at all with Zoom. Grading criteria was so unclear that many students didn't know why they were losing points. Heavily deducted points for using calculators in *homework* as well as exams. We could not skip any steps in showing work.

Professor Luong Le was my worst professor I have taken. It is difficult to understand him and his lectures, so any help he offers was not helpful. His tests were not that hard but then he takes points off for the most trivial things. He even proudly said the average for his tests was 60%. He didn't know how to use zoom. I wish I could say more.

Um do not take his class unless you want to fail. I walked in the first day and these were the first two things he said: Homework is incredibly important A 50 on a test is good... Not something you want to hear. He is very hard to understand, gets upset when asked a question, makes you feel very small, and grades incredibly hard.

This Professor seems to always be rushing tests even when his students are ready for them. He will mark points off if your work is done by a different method. His tests are hard and says anything above a 50 is good. He grades the hw very hard which will bring down your grade, most kids would get a 13/20 on it and will not always answer hw questions

Beware of this Professor. I have never struggled in math before like I have with this instructor. Unclear expectations, trick questions on tests, and poor communication define this teacher's style. He proudly states that he doesn't want his students to pass, and seems to get a perverse enjoyment over watching them struggle. I would give him a 0/5.

Genuinely thought I would be able to survive his class by constantly reviewing his notes and the chapters, but nothing would work. Asked for too much on his exams and got frustrated with everyone if we didn't understand, but never clarified himself. Students would have to constantly correct him at times. Not a fan of his style of teaching at all.

This was by far the worst teacher I took at COC. He gave no help and it was so hard to understand anything he said. He basically just copied the notes online in class and that was it. He would call us stupid and tell us how terrible we are. Would never recommend or put anyone through what we had to go through.

Was very rude and did not explain well. You have to ask for him to explain the lesson or he will just show the notes.

I strongly advise you never to choose this teacher

I strongly advise you never to choose this teacher!

Expect significant amounts of homework and little to no useful feedback as well as a lack of mathematical rigor in explanations. Don't recommend!!

I don't think this professor is a bad guy. I just don't think he's a very good teacher. At least not for me. He has a very heavy accent, make frequent mistakes, gives too much hw that doesn't match the tests, grades the tests more than hw, teaches the class like you've already taken calc, etc. Be prepared for no social life if you take this class!!

As a mathematics major, this class only had a little correlation to relevancy in my future endeavors. Whilst applying math concepts, he majorly focuses on incorporating non-math concepts that aren't relevant to hall. You will find insanely large amounts of homework that take days to complete and average test scores as high as 51%. Good luck.

Mr. Luong Le was probably the worst teacher I've ever had. He would make fun of students, crack offensively inappropriate jokes, & bragged about how hard his class was and how only 2 students ever got an A in the history of his class. He was so bad at teaching that he added 20% to every test score just so that enough students would pass. Beware.

If you registered or planned this class you should remove it IMMEDIATELY. This professor is not good, with the first exam coming up he told the whole class he was scared for us. And that we will fail. His lectures sometimes do not correlate to the homework. Overall, awful class and awful professor.

His in-class notes were extremely messy and hard to follow. He made mistakes constantly, sometimes without fixing them. Very tough grader, as he expects you to complete every problem a certain way, but won't explain the correct method. Homework felt like a chore, and was sometimes unrelated to anything on the exam. Overall worst I have ever taken.

Mr. Le was nice for the first week, then he snapped. He got really bad once we started inverse trig functions. His methods of teaching can be very difficult, as he doesn't accept any other methods. To reiterate, my friends and I, have all come to a conclusion that there are much better methods of learning, and in his sense, teaching. Not very good.

Very hard grader, if not done his way it's wrong, tests worth practically your whole grade, homework with 200+ problems that take hours to complete, hard to follow lectures while expecting you to know the material before entering the class. If you're taking this class, say goodbye to your social life as it takes 10-12 hours weekly to pass.

Luong Le should consider retiring. Awful teacher, does not teach well at all. Very condescending. He preaches about how he taught in the UC system for 5 years, I am more then certain he got fires because of how bad of a Professor he is. DO NOT take him.

DROP THE CLASS WHILE YOU CAN. You are expected to know the lesson when you come to class. The lectures have nothing to do with the homework assigned. If the problem is not done his way it is considered wrong. I had to drop the class because I didn't understand after getting tutored and asking him for help. Please be ready to lock in or drop.

please do not take this guy he assigns so much hw thats not even correlated with his tests. whenever you want to hate him you end up feeling bad because of his old age which is just annoying. first week he may seem sweet and easy but please change profs

horrible teacher literally makes us calculate factorials instead kf lettig us use calcs

Please drop his class he literally is the worst professor ever. He assigns a textbook and even calls it stupid and when we follow the hw just like the textbook, he'll say that was wrong which is like why are you even assigning the book in the first place? He expects or wants you to know algebra already and he assigns so much hw its crazy. good luck

run. even if this class is mandatory for you and you need to take it. just dont. its not worth it. trust. literally any other solution than taking his class would be better.

At first I felt bad because he is working at his old age but he is very rude in general. In front of another student he made a rude comment towards me which was,“ let me help you, she is gonna ask to many questions”, even though I'm asking the same questions as the other student was asking. I don't recommend his class to anyone.
