He greatly cares about students, and he lets students know exactly what types of question will be on exams. He helps all students succeed. With hard work, the class is very do-able. Although English isn't his first language, he is understandable and clear on lessons

Accent makes him hard to understand at times but other than, I would highly recommend him. Extremely helpful with questions and he tells what problems will be on exams. He made Diff eq simple for a complicated subject. He has a nice grade curve and really took the stress out of a summer class. He is the best Math professors I have ever had

After reading the comments in here, I was reluctant to take this class on-line, but I am glad I did. It was the best math class I have ever had, and the grading was pretty good. 50-60% of the grade was from homework and participation, and the rest is physical exams on campus. He even allows a Makeup test for Midterm when you want a better grade.

Homework and participation are worth a lot of points so its not hard to pass the class but written homework is difficult and you have to scan the homework

Mr. Li is a great teacher and he cares about his students a lot. He was more than happy to help with any questions I had. The online homework is worth a lot of points, but it's easy to get 100% on it.

He is a great caring teacher. I took this class as web-enhanced. Each week, you have to do an online homework, a written homework, and a few posts in discussion. Written homework can either be scanned or written in MS Word. There are 3 exams: midterm and final on campus; an optional makeup exam that gives you the option to replace midterm's grade.

Took this class online - HW due dates were Monday's so had plenty of time to teach myself how to do everything over the weekends. Li is an excellent mathematician and very helpful if you visit him during office hours. LOVED the book and no-calculator rule. Questions were simpler and if you understood the concepts you did well.

I went from liking math to diliking math and now back to liking math again thanks to Professor Li. He makes calculus look easier than it is. In order to succeed in this class you'll have to takea a lot of notes and and stay up to date on all of the lectures and assignments. He also encourages students to ask questions and will responds promptly.

Actually strengthened my knowledge of previous math classes, he actually makes everything make absolute sense. His English isn't perfect, but I do not have any problem understanding everything. The tests are straight-forward and the homework is easy to get 100% (Unlimited attempts) He encourages discussion as well, which is great advice.

Very hard class, but super helpful.He wants you to understand the material. Don't take if you have test anxiety. If you test well, this class is a no brainer.

Professor Li was very willing to help students. If you cant learn on your own, for sure you shouldn't take his class. Online class requires you to be an independent learner. His notes were always clear and helpful. I don't know what people meant by saying they cant read or understand his notes. Well, at least not my case.

I found this professor very helpful, He answers any questions you post on D2L within an hour most of the time. I find his English just fine, it's an accent it's not broken English. He does try to get people involved in class, but sadly most math classes are pretty quiet classrooms for some reason. Take advantage of the resources provided.

He was very quick to answer any questions on the forums any day of the week or time of day. He is strict about turning things in on time in the correct format, no exceptions. He doesn't allow makeup tests. His tests, however, are easy as long as you do your work during the semester. On the final he gave the answers to about 5 questions.

I had Prof Li for Cal 1 & Cal 3 & got both "A". He is very helpful & make sure we understand every single material. His accent is very strong, but study with his lecture you should have not question anymore. Review his lecture and finish homework by yourself, you will do good on the exam. If you end up have lower than a "B", 100% is your own fault.

Professor Li was quick to answer questions, no matter when they were posted. The online materials and homework provided good preparation for the exams. This is the first completely online class I've taken, and it worked out quite well.I would recommend this professor and class.

The class was well organized and planned out. Professor Li was concise, clear and answered the questions in timely manner. The participation played a major role in helping me understand the materials. The exams will not be difficult as long as one review the lectures and do the homework. I strongly recommend this professor and the class.

I got two tips for his course: DO the homework and STUDY his Practice Exams for his midterm and final. He provides an abundance of information that is very helpful to the course. Exams are easy as long as you study the Practice Exams 2-3 times. I only did the Practice Midterm once; I got a C. Did the Practice Final 3 times; I got a near perfect A.

Professor Li is very nice and very clear on what is due and when. The part that got me was the discussions. I recommend just doing them because they're worth 30 points at the end which could help you a lot after all the tests. There are no formal lectures so if you want to learn, you have to read and watch the videos.

This class was laid out with very clear expectations. It was a lot of work, but there was a lot of support that students could take advantage of.

He's a good teacher, understanding and gets back to student as early as possible when student ask questions. sends emails out in due times and gives good time to reply/respond.

Best path to success for me: Use the online homework to learn. When you get to a problem you don't understand, you can go to the chapter content or watch a video lecture about that topic. Then the question has a lot of tutorial helps such as examples. Use a math tutor (free at all mnscu schools, I think). The exam samplers are awesome.

Teacher always available for online questions. I like this online class.

He was always punctual and expected the same of his students (only one class was cancelled). He stuck fairly rigidly to his curriculum and provided online notes, extra practice in and out of class, as well as a resource for asking him questions directly. Only used online homework service, not the textbook whatsoever.

Professor Li was excellent. He has high and clear expectations appropriate for the level of math. He provides a wide range of resources and answers very quickly when you have a question. Rather than give you the answer right away, he asks you questions to provoke thought. Professor Li always looks to improve himself which I respect greatly.

To be honest, I took his precalc class because its required for my degree. I STRUGGLED to get a passing grade but that is because of my own lack of math capabilities. He is very straight forward and incredibly helpful when you ask for clarification. One of the nicest professors I've had. I would take another one of his classes if it weren't math.

Good professor

Online - good class for busy people or with odd schedules. Quite a bit of homework but it is all relevant and helps prepare for tests. Tests are difficult but appropriate for level of class. Professor answers questions very quickly and is responsive to students. Overall good class. Do not take unless you are self-motivated.

Very good

OKAY! I have taken him because i couldn't come to school everyday for a 50 minute class. And let me tell you HE'S AMAZING! the grading criteria is CRYSTAL CLEAR. practice exams are EXACTLY the same exams. weekly homework and bi weekly written questions which are easy from the book. I'm taking him for Calc 1 now and will take the rest with him.

For an all online class, professor Li is EXTREMELY quick to respond to discussion board posts which is a small, but graded part of the class. Overall, online pearson hw, 4 written book hw assignments, 2 in person tests which follow the practice tests closely. Be prepared to teach yourself however, so the online hw site is awesome & youtube.

Professor Li has the following grading scale: 100 points for weekly homework, 75 points for both exams, and 150 points for the final. This rubric is clear, but doesn't give wiggle room. His lectures are incoherent but his slides that he posts online are fantastic. This professor makes you work to understand. Difficult but absolutely fair.

calculus 2: I found his lectures to be very engaging and helpful. He's a very up beat positive guy who genuinly wants his students to succeed. I found the course to also be extremely fare in how it was set up. His lectures were far easier to understand than any textbook. paying careful attention to him in class saved me time and work.

She is good.

Homework is relatively and the textbook is very clear. If you email the prof he responds with detailed instruction. If you take the asynchronous class don't expect him to be synchronous. Most students complained about things that are just normal with online. Take the class in person next semester if online just isnt your thing.

Has fantastic notes, also the software he uses is a great textbook. That yes takes points off for the wrong format, but by week 3 you should be used to the format. Homework questions are just like the quizzes. Making it easy as long as you get the homework down. He's reasonable and does the job which is frankly teaching an online math class.

Calculus 2 is not an easy course if compare to Calc 1. Pro. Li is quick responder; I always notice that he responds my questions just in a few minutes. The class use Pearson MathLab, so the best way to get a good grade in this class is to spend more time doing the practice work problems (study plan). The tests and quizzes are timed.

This class was VERY easy in the fact you could use the study plan and practice the EXACT types of questions that would be on hw and quizzes! His lectures only had a few problems per lecture, but I honestly didn't need them. If you practice the Study Plan, you'll be able to ace the hw (unlimited attempts) and the quizzes + midterm (two attempts).

In Calculus II online, most of the class is self-taught. The quizzes will have the same questions that are available on the study plan, so you can practice the exact problems before hand. This is a completely online class, the professor will respond if emailed --- Overall, I liked him, but again, this class is only done through Pearson.
