He is the best math teacher i ever seen. You may not like him the way he explains however, he is very helpful, easy, clear, and understanding.All you need to do is go to his class, take notes, do all the home work. If you do all the home work and understand the review materials there is no Away you will get anything but Also he gives a huge curv.

HE IS VERY GOOD AT WHAT HE DOES, HE HELPS YOU OUT AND IF YOU TALK TO HIM HE WILL GIVE YOU A GOOD GRADE. HE IS THE BEST CALCULUS PROFESSOR IN THE MATH DEPT. TAKE HIM, YOU WILL NOT REGRET IT

Dr. Lee is excellent. He explains everything clearly. If one of the students do not understand something, he would go over it until he understands. He drops one of the lowest midterm grades. Highly recomended.

He is a very dedicated. He is patient and respectful to each of his students. When I take a note, i can tell how long he spend his time for the prep of his lecture. He is a little bit fast, but, overall, he is good and well rounded Professor. If you are to take m 110, take him.

Passed all exams but the material was a little confusing because he didn't explain enough. He also does mumble so you have to listen closely.

nicest most amazing professor you will ever have in college. very easy to get a good grade. however he isn't strict so you have to motivate yourself to do the homework i went to maybe half the classes (8am) had a 87 test average and he still gave me an A in the class. also lots of extra credits and bonuses.

One of the bests. Asanon Math major student, I really enjoyed the class. His lecture was clearandeasy to understand. Always there were reviews for exams and no surprise.

Though Queens College don't have many good professors, this guy helps a lot. He gives exams that make final exam by math dept. a breeze. He's even willing to help after class if you don't understand something in class. A Highly recomended professor at Queens College for anyone who's taking Math.

what a nice guy!! he's just really cool and calm and makes the classroom a chilled place to be without the stress - he's a little forgetful but hes a grad student also and juggling it all so i give him props just for always smiling and being happy.

I think he is the nicest professor ever. He is a grad student as well and has a lot on his plate. His lectures are clear, all on powerpoint, he puts in a lot of work into it. He is really nice and helpful, sometimes people give him 2 much hard time. This is the second time I have him and think he is great!!! Really pleasant and nice too.

D.L. is the best math professor to take! he is extremely nice and is willing to answer questions anytime ~although he does move fast he explains all the material very well~ def take him

Great pysch class to take if looking for an easy grade

i really dont like math much but lee is so great..he's really nice and doesn't mind helping out students. He gave extra credit also. I'd definitely recommend him if you need to take a math course.

He's a great guy truly but I think those of us who took him this summer underestimated him a little. I do think however that the first exam was very tricky, but he certianly made up for his short comings on the final exam. If you are going to take Psych 214 take it in the school year so you have more time to study its NOT a class to take lightly.

Best teacher... take him, trust me you will not regret it... he is hilarious and a great teacher... his review sheet is exactly what is on the test, just diff. #'s... I wish he taught more classes.

great funny and easy I got a 100 on the final and A+ for the whole class, take him and you will never regret it

He is really great professor who i ve met. He s so clarified and he teaches u step by step. highly recommend him. I hope he teach the other classes.:(

His class is super easy. He can go fast but if you ask him he will take the time to explain it better. His test are formatted exactly like the review sheets.

BEST PROFESSOR EVER! Take his class, you will NOT regret it. He's amazing, funny, makes class entertaining. Loved his apples and oranges examples.

HE IS A VERY GOOD PROFF. HE GOES THROUGH EVEYTHING ND GIVES OUT A REVIEW SHEET BEFORE EXAMS AND IF U DONT UNDERSTAND ANYTHING.. HE WILL TAKE TIME TO EXPLAIN!

Professor Lee is an awesome teacher. I only took this class as a requirement and I ended up loving it. He explains the material extremely well and is very helpful, we constantly practiced the problems. He does have an accent but you'll get use to it and he is really cool, always cracking jokes. I got an A+ in the class. I def. recommend him.

Hes the best! he goes out of his way to make sure u understand,hes funny and easy to talk to. there is no way you will get a grade lower then a B+

i hated math before his class. He is so great! he really tris to make things as clear as possible, even giving 10 point easy extra credit. His grading is more then fair.

super easy! I learned more in his class then all the years I have been forced to take math.

Great professor. I learned a lot from his class. He explains everything very well and goes over all the home work. Very patient with the students. Take him. You will never regret.

One of the best Math teachers in QC. He is extremely efficient and his lectures are absolutely crystal clear. If you understand the Home work and class notes, that's enough for the quizzes and exams. I was never bored or lost in his lectures. I am glad that I had the opportunity to be in one of his classes.

He knows the material very well and teaches math concepts very claerly. I didn't like math before. But he changed my whole view of math. His class is easy and enjoyable. He really helps.

Very good teacher. If you keep up with the classes do HW problems you will do fine. Quiz every week, during second half - take home which reduced stress. EXAMS no surprise; problems from HW and past quizes. He knows material very well; provides good explanation. Willing and encourages review of HW problems; he picks some on his own to review.

His teaching is crystal clear to undertand. He always comes to the class half an hour early and answer all your questions. He takes care of all homework questions in the class. He is very patient, nice and helpful. One of the best math prof. in QC. One thing bothers is that he gives too many quizzes and exams.

Excellent teacher. Explains everything you need to know to get an A in the course. He basically gives you what to expect for each exam. As long as you study, you can really get an A. He explains everything well & is definatley on the students side. A+

Professor Lee is very much gifted teacher. He teaches difficult calc concepts so well that everyone may understand or may have a better understanding. I am so grateful to pass the course with an "A" this Summer after failing twice. I attended all his classes, and took all quizzes and exams. I never was bored in his class.

Professor Lee is the best Math professor.I took his class for summer 2009 and I don't regret it... Calculus is a very hard subject but made fun and easy to understand.. He is very understandin and helpful...

When I took Math 151, I got 3 midterm all above 90, so my final exam is exempted, and become an automatic A+ for the course, tests are fairly easy compare to what typical calculus courses are. He's korean, very kind person.

GREAT professor!He makes the class easy for you to get an A in. He gives homework but it is not mandatory to do. He goes over the questions that will be on the tests. 3 test 12 quizes on every week but he drops 2. He offers a few extra credit assignments.

Great Professor, very kind and understanding. He will do everything he can to get you a good grade. He explains anything you need to know very clearly, although his accent can be slightly confusing. Tests are easy and mostly based off of what he just taught that day and the day before. Great class to take to boost your grade.

Professor Lee is very fair. Calculus is very hard to begin with but if you keep up with the work/homework, you should do very well. He is a fair grader. Tests are on what is taught. No surprises.

Professor Lee is very understanding. I've had him for math 115 and math 122 and they were EASY. 3 exams and 12 quizzes. He drops the lowest 2 quizzes and the lowest of the 3 exams. Just keep up with the homework and you will definitely get an A.

This is guy is very laid back and understanding. His makes math fun and challenging. Yes, at times he skips problems but his excuse is "experience". He makes math fun also saying this "is not important like your ex". Took him for math 151 and I do not regret it one bit. Very nice guy. If you do work you will be good.

Discrete Math for CS maj. It was 2nd time for me to take this course. A quiz was given every week + two midterms and final. The topics are broad and scattered but the class was focused and comprehensible. The class started 7:45 am, which was not easy to manage. But it was really worth to take it.

Decent Prof. He is very nice and wants to help. Sometimes he's a little hard to understand. I had to learn some stuff on my own because I didn't understand in class. He gives quizzes often to check if you did homework. Tests are not so hard.

He makes corny jokes but it's cute because he thinks he's hilarious. He gets confusing sometimes but he'll explain anything if you ask. He gives quizzes every week and drops two of them. Gives only three tests drops the lowest. If you do better on the final than your actual grade, he uses that as your overall grade. Doesn't check homework like that

He explains very well and makes math easy to understand. He is patient to answer yours question until you get it. Make sure you do homework for the quizzes given every week. Highly recommended.

He makes Descrete Math easy to understand. He is funny and good at explaining problems. I have enjoyed being in his class. This is second time I have taken this course. I can confidently say Prof. David Lee is far superior instructor than others.

Decent and friendly Prof. I took this course over the summer 2017--NO regret for one second. He teaches well, BE mindful that in the summer professors makes their own final. Quiz was given every other day. He was nice-drops lowest test grade. He explained the material very well and was ready help...

Awesome professor. Class for elementary school teachers. Learned a lot from this class.

He makes funny and corny jokes and he is hilarious some times. He is decent and friendly professor: Patient and helpful. Summer course was very intense but worth.

Go to class and actually focus on what he teaches. Free A.

Four midterms and a final given. You should expect quiz every week and Webassign homework for every lesson. Excellent lectures recommended.

This class is for CS majors. His lectures are very clear and understadable. Fair grader and caring.

He is the best Math professor that I have had so far.

He is very knowledgeable, but he performs expecting you to know pre-calculus already. This was a very tough class because I took in in the short summer session (4 weeks) with two quizzes and an exam every week. Don't take pre-calculus in the summer session unless your trigonometry is solid!

I swear to god this man is the funniest professor ever, clear grading, if you are cool with him he will help you out. Tests aren't hard. Just study the topics.

The goat

Great professor, the best in math that I've ever had. quiz each week with feedback, didn't get mad if you interrupt him, always had time, always nice, and happy. He makes math less stressful.

While Professor Lee is a man that moves at a fast pace he is very forgiving and caring of his students if they do not understand the material. He gives Pop quizzes once a week but its on the material he teaches in the previous classes and states what topics they will be on. Of course they are not difficult but review alot because he moves fast.

the best professor ive taken in queens college. professor Lee makes the material really easy to learn and he takes his time explaining if needed. weekly quizzes are also very straight forward, he tells you what will be on it. 10/10 recommend!

Professor Lee is an awesome teacher. He gives very clear lectures. He demonstrates massive examples in the classes and sends emails of reviews & reminders, he answers all questions. Yes, he gives quite a bit quizs, thus you get more chances to average up your grade. He is not only a great teacher but also a very kind warm person.

awesome

Consist mostly weekly quizzes (total 10 or 11 with usually 4-6 questions),homework that isn't part of the grading criteria (give it a go to understand the material), and great reviews before quiz/exams by zoom (if you understand the review, you'll be fine). His lectures are quite fast-paced and come out confusing, but overall great professor :)!

He is very understanding and caring professor. He answers all your questions and makes things as easy as possible for anybody to understand. The course is very heavy to take a quiz every week and three exams and the final. Overall the class is very pleasant and enjoyable. GOAT...

Lots of contents and topics to study. For each class you are to watch videos made by Math department. In-class work requires active participation. Questions of quizzes and exams are from Open-eBook and the examples in the videos. Overall, the class is very entertaining, and there will be a lot to get out of this course required for CS majors.

I really enjoyed the way this class integrated the concepts of discrete mathematics with CS . It was fascinating to see how these mathematical theories underpin so many aspects of computer algorithms and data structures. Plus, Professor David Lee's engaging teaching style made complex topics more accessible and interesting.

What I like most about this class is the way professor David Lee teaches us to get a better understanding as well. He also is both entertaining and is able to review important material before a test. When he has time, he'll host review sessions the day before an exam.

David Lee is overall a pretty good teacher. However, it is noteworthy to point out that his class favors people who learn mostly through self-study. His lectures feel more like a review of the videos he encourages everyone to watch outside of class. He has 10 quizzes and drops 2 lowest scoring quizzes. Do well on quizzes and you'll do well on Exam.

Clear instructions on the materials for the quiz and exam plus Professor will email you the review materials. You gonna self study for the knowledge by the video clips. And Professor will go over it during the class. He is very nice and happy to answer student questions. Also extra credit on the exam. Recommending his!

Good Professor, however, it is to note that this class is very self-study heavy, so look on at the videos!

Watch all the videos and finish all classwork and the class should be incredibly light. Professor Lee also teaches the content really well. He encourages student participation to answer example topic questions to ensure that the content was understood by everyone. There's no graded hw but I HIGHLY suggest again to watch videos and do work to excel.

Math 122 has been such an amazing experience for me. The course is really well-organized, balancing challenges and support perfectly. The concepts are explained in a way that's easy to understand. He is super passionate and always there to help and motivate us to do our best. I highly recommend Math 122 with Prof Lee.

It's a heavy 4 credit course. There will be quizzes once a week and 4 exams. The attendance matters but not mandatory. The lectures are to the point and excellent and the pro is caring. The grading criteria is fair and clear.

The course is excellently structured. The concepts are presented in a clear and easy to understand manner. Professor Lee's passion for teaching shines through, and he's always available to guide and inspire us to excel.

I had the privilege of taking Math 120 with him, and it was one of the best academic experiences I've had. He explains concepts clearly, provides helpful examples, and is always patient when answering questions. His teaching style makes even complex topics easy to understand.

He is one of the nicest professors I've had the pleasure to meet. All the content is online for this class so when you come to class, you work in groups to complete a worksheet. He gives quizzes every week but they are extremely easy if you watch the videos right before. Overall, it's a very easy class and grade because he is very helpful.

Math 122 has been a fantastic experience for me. The course is highly organized, striking an ideal balance between difficulty and guidance. The concepts are presented in a clear and accessible way. Professor Lee is deeply enthusiastic, always available to assist, and consistently inspires us to excel.

Fast teaching style, read ahead of time

Took the summer course so I won't have the same review as others, but he gives 12-13 quizzes which could screw you over if you don't do a little bit of studying before hand and paying attention to the videos. Midterms and final are fair in terms of difficulty. Course is like a mix of statistics, precalculus, and expanding upon basic math knowledge.

The class is all just watch videos online before class, rewatch a some of them and go over it in class with homework. he takes time to ask if anyone doesnt understand and will go over questions explaining
