If you don't speak english, this guy is perfect for you, he doesn't either! Can't answer your questions, can't understand your questions, you can't understand him. Curves well at the end of the semester, tests are not easy however, no homework due all semester.

this was by far the worst teacher I have ever had. He couldn't explain anything. He was very unfair and should be fired! Why do they hire teachers that dont speak english?

He lectures but does not teach! His tests are 6-8 questions, if you miss one you fail basically. You can not understand his accent! He doesn't answer questions. He makes mistakes on the board. He says he doesn't grade on a curve yet a 60 on a 100 point test is OK? His explainations are confusing. I haven't learned anything and I love math.

even though he is extremely difficult to understand and has virtually no social qualities he was in my mind a good teacher. this is a class where you will have to learn a lot from the book. he's not very demanding as a teacher, and the tests are always easier than you thought they were going to be.

Jun Ling is a nice guy but a terrible teacher. He has a thick Chinese accent and has no idea how to teach. I've never complained about a teacher before and I think he is the worst teacher I have ever, ever had. Do not take this class.

Oh my gosh! This guy is, like, the worst teacher on the planet earth! I agree with all those who spoke negatively about this guy. How he's still teaching is beyond me. Seriously, he could teach to Forrest Gump, and he'll still fail. Seriously, he got assigned an award at UVU, and I was NOT impressed. He should eat dung for a living after this trash

Ugh, possibly the most arrogant person in the world. There's no way I ever want to get taught by him ever again.

He was the worst professor I have ever had. I usually am really good at trig, but I never could understand him. Plus whenever I tried to get help from him he just called me stupid and walked off. I'm really surprised he is still teaching because he is an absolute failure as a professor.

Absolutely horrible. You can't understand a single word he says. So if your good at understanding a convoluted textbook and you don't need explanations from a teacher, take him. Otherwise, don't. The guy needs to look for a new profession. Horrible

Absolutely, and completely terrible. His pace is atrociously fast this compounded by his accent makes his class about impossible to learn from. if you take this, please understand that you will be teaching yourself because he is totally and utterly useless.-sorry ling but teach somewhere else.

His accent is easy to get used to and even enjoyable to listen to sometimes, but I am good in math but he confused me more than he helped me. I found it better for me to not go to class and figure it out on my own. The only problem with that is that he does quizzes at random and turns in HW at random.

He was very nice and knowledgeable but the class was not good. The accent killed me. I took a full semester of his class and I still can't understand him. His tests were hard and I didn't feel he prepared me for future math classes. I taught myself from the book and only pulled a C when usually math is one of my best subjects.

Hardest teacher I have ever had and I actually enjoy math. His accent is so unclear and he never helps students understand the material. One midterm the class average was 52%. There are easier professors I promise!

Belittles students in class, tests are on nothing he taught, and if they are, impossible to solve. Harsh grader, no extra credit. Cares nothing about the students. Two midterm tests had a 53% average! Goes over only proofs and picks up speed with teaching every minute. Save yourself and avoid this teacher at all costs!

He loves his math. You can tell it excites him. His lectures are confusing, and is very fast except when graphing, then he takes forever. Usually one of the first out the door. No extra credit. No tests dropped. No notes on exams, but plenty to memorize. Difficult accent. About 8/40 people attend class regularly. I don't know if the rest dropped.

Be ready to read a lot because you won't be able to follow his lectures.

I took Calculus II from Professor Ling. Bad idea. His lectures are awful, to understand any of it, you must study the material thoroughly beforehand. He didn't finish all of the material in the class. He skipped the last chapter and the second to last chapter, he dumped on us two days before the final. His tests are pretty difficult.

If you are not already fairly proficient in math then I would suggest finding a different professor. He is pretty difficult to understand. I would suggest reading each chapter before attending his lectures. He does not use canvas, so you have to meet with him if you want to know what your grade is.

He just goes on and on about the topic for the day and if you don't know anything before class you could get lost real quick. He knows his stuff and if you keep asking questions you'll eventually get what you need, but it was tiring. I luckily had 2 people in the class i could talk to about the stuff he talk about, but most of it went over my head.

He is very hard to understand. The grading is very inconsistent from student to student. He doesnt answer questions very well and I think it was the language barrier that caused the problems. I learned more from YouTube and the book than I did from professor Ling. He also doesnt post grades or what the curve is on test till the end of the term.

This is one of the worst and worst professors I have encountered in my two years of enrollment. He is very perfunctory in replying to any message no matter how you express it, and sometimes he will not even reply to your messages. And his lectures are boring and boring, even you can only get knowledge through books, maybe this class is the only one

He knows math but doesn't know how to teach. I resorted to learning Calc 1 on YouTube. He also doesn't post anything on canvas so you have to ask him what your grade is. My 3 friends all did very differently on tests and when we asked what out grades were he would pretend to think about it then say "probably a C". Worst class I've ever had.

I'm sure he is a great professor, but I wouldn't know because I can't understand him. There is a serious language barrier here, his accent makes it impossible to keep up with the lectures, and the worst part is that he tests you on what he teaches in class, not what you can learn from the book, so this class is impossible. Also a very harsh grader.

Professor Ling is very passionate about the subject, but he is very proof heavy and does not like to include examples. There are no reviews for the given tests and he is very inconsistent on grading between each student. The language barrier had a huge impact and I mainly taught myself from the book. I would highly recommend a different professor.

Professor Ling was inconsistent in grading, took weeks to grade things, and is not good at lecturing. One of our test averages was a 54.9. I learned strictly from the textbook. He does not give partial credit on problems and only cares if you got the correct answer. I would transfer schools before having to take another course with this professor.

The presence on canvas is basically none. The midterm and final make up all your grade and the average on those in my class were 50 and below. With that being said the tests are also not curved. So, don't take this class unless you want to fail it.

The biggest issue I have with him as a professor is his thick accent and his inability to teach for understanding. I ended up just not going to class about a third of the way through the semester because the things he would teach wouldn't ever help me with the homework. I ended up having to basically just teach myself the material.

I understand that he is a VERY smart man, no doubt about that. He is a genius. But he is extremely hard to understand. He weighs his exams at 90% of your grade, so you have to be near perfect to pass the class. There is no extra credit or test corrections and they are not curved. Homework is pretty much useless to your grade. Good man, bad teacher

He cant teach and has a very very thick accent making it really hard to understand him. He only ever goes over proofs and doesn't ever teach you ways to actually solve problems. Half of the problems on the assignments i had never seen before in class. I never skipped class and still had no idea what i was doing.
