Energetic and highly interested professor. Shows a genuine care for his students and adaptability to their needs. Is always asking for feedback and seeking of ways to hone his pedagogy.

I love him. He is hilarious and highly informative. The homework can be a bit time consuming and the tests are based off of them. His office hours are fine and he is very cooperative with students who apply themselves.

Very helpful professor. His quizzes are based off of the homework he assigns in class. Do as many bonus points as possible because the tests are extremely difficult. He designs them to average a 65% or so. Overall a great professor, though it was difficult.

Dr. Chen is amazing. The homework is very time consuming but most of the tests and quizzes came directly from it. Tons of bonus points too. His office hour is super helpful!!!! Always willing to work with students and makes you extremely comfortable. Remember firmly to find him before the tests, that can really be a change of game.

My favorite math professor in UWL!!! I never found calculus so interesting and I am a chemistry major .His test is not hard once you understand his notes. Just got my test 2 back and it was much better than I expected.

He replies my email on 12:30 a.m. Saturday.

Definitely take Dr. Chen is you can! He's super helpful and genuinely cares about his students' success. He also takes the time to get to know his students too which is great. His tests can be hard and the homework is time consuming but he always offers extra help at his office hours. I would highly recommend him

Amazing professor! And I don't think his test is that hard. Most of them come directly from the homework and the quiz (which are not easy fairly speaking). However, be prepared for True and False questions (which always screw me up) in page 4!!!

Just finished his final 10 mins ago. Love him!!!!!!!!

My score is ready in less than 12 hours. Very fair final exam. Super helpful too!!!!

Great professor, the course material was often challenging, but I was somehow able to pull through pretty well. I wish we could have a formula sheet for the huge amount of formulas!

Always willing to help! Can be a hard grader but if you actively participate with homework and office hours then you will do just fine.

I took his Cal I, II, and now in his linear algebra. Best professor ever! Super smart! Always willing to help. Yep, his classes are tough but hey, math is tough and he's not sugarcoating it. In fact, he's the only professor that makes me want to learn more maths even though I know I suck! If you are ready for some serious math! Take him!!

He is a difficult instructor and his exams are difficult, but he pushes you because he knows you can do it and believes in every single one of his students but you have to put the time and effort in order to get that which I really liked about him. I definitely developed an appreciation for mathematics that I never thought I would have!

Originally I hated Dr. Chen. But by the end of the semester, I really grew to appreciate him. His tests are very difficult but he gives a lot of extra credit opportunities and homework is easy points (and worth a lot!) Make sure and understand the most difficult problems in your homework because those often show up on tests.

He's like every comments said, super helpful, super inspiring lecture and yes, he does push you to your limit of understanding. I hated his programming assignment at first until I realize how important it is. His linear algebra opened my mind and changed the way I view the world. Definitely take him if you care about learning.

His lecture is super inspiring. It was hard to follow at first. Everything start to make perfect sense once I catch up with the pace, which means, I to constantly preview and review the definitions as he told us to. After that linear algebra became the most useful and interesting math class. His test is hard but my grade turned out to be OK.

Great teacher. Very passionate about what he does. He moves extremely fast and expects you to know all of the material pretty in depth. I would suggest taking him to learn a lot, but be prepared to work your butt off!

He is a very difficult professor. He is always giving extra credit problems and is always willing to answer questions when you have them. Tests are difficult. Make sure you are well prepared and study a ton. Lectures can be confusing and hard to understand. Very fast paced.

Dr. Chen is the hardest math professor I've ever had. Be prepared for tons of homework, coding assignments plus 20 mins content preview per day. Don't get me wrong, I enjoy every minute of his class simply because linear algebra is awesome and Dr. Chen's lecture blowed my mind! If you are ready for some serious learning, take him in a heart bit!

The first chapter is by far the hardest to understand. If you just push through the first chapter, you will be fine. You'll get used to how he talks (he's originally from Asia) and once you do, he'll be easy to understand. Go into his office hours, he'll most likely give you extra credit just for coming in!!!

Very interesting personality. Treat you like friends (he's very young). Very inspiring and caring. Tests and quizzes are not that tough if you listen carefully to what he says. Do make sure you have at least 6 hours a week to work on the material. Linear algebra is overall a tough course.

Chen pushes students to study independently and within a group. He gives optional bookwork and mandatory online homework that is used as a grade. His tests and quizzes have almost identical problems as taken in the notes. Chen also gives multiple opportunities for extra credit and is more than willing to explain homework problems in class.

Dr. Chen is hands down my favorite professor in UWL. He's not just a math professor but a great mentor for my life! Take him at all cost! You won't regret!

Very cool guy! Extremely smart. Always willing to help. And hilarious in a very different way (he's Asian). He's test is tough but I guess I can't complain about that. Overall the best teacher I've ever had in my life! Take Dr. Chen and learn to love math!

Chen is one of the best math teachers I have ever had. He has a bit of an accent, but still manages to explain things better that other math teachers. He makes math less boring, exciting actually if you can believe that. Very helpful both in and out of class. Friendly, easily approachable. Really shows that he cares about students.

Numerical method is the most interesting math class. The homework is very time consuming and you will learn tons of useful stuff. The content is hard, but homework and projects are free points and count for 40% of the total grade. Be sure to talk to Dr. Chen if you are trying to find a job with a math major. I wish he was my advisor.

Hands down one of the best professors I have ever had. He teaches everything really well and you know what to expect on the exams. With that being said, you still need to do homework and work hard to get a good grade. He does give out ALOT of bonus points if you do extra work. He really cares about his students.

I want to write the review before the final exam so I stay neutral. Dr. Chen is a great teacher, gives super good lecture and cares about his student a lot but his test is the hardest. I got frustrated after every exam but I just can't hate him for making me better. If you are serious about learning math, take him!

He is a very real person and not in anyway unpredictable. He's very inspirational and puts himself before his students. Despite that Dr. Chen has an accent, it actually helped me to pay attention; considering, he is slightly difficult to understand. Overall, a wonderful professor and person.

Dr. Chen makes you work for your grade - but good news is that he really makes sure that you learn the material. Dr. Chen cares about the success of his students which is why he is a tough grader. If you're looking for an easy A, don't take him. If you want to learn calc I and go onto Calc II, highly recommend him. He has office hours every day too

Dr. Chen is an overall great professor. His coursework is quite difficult but what can you expect, it's math. He is definitely there to help anyone that needs it and will occasionally give free days where he gives a presentation and doesn't care if you sleep. The syllabus seems intimidating but its much less daunting than it seems.

Smartest person I've ever seen. His test is difficult but he offers tons of bonus point by doing puzzles or going to math talks. Shows tons of cool stuff in class and tells the most interesting stories during office hours if you can get him to start. Highly recommend to anyone looking for a general intelligent mentor.

Great professor! His lecture is inspirational and he really cares about your success. I would recommend taking him for any class. Get ready for one of the hardest class though. My only regret was that I focused more on my other classes and not enough on his.

If you want to work, he wants to help. He's passionate about his career and teaching, and will help you if you work for it. He won't hand you a grade, but he will help you lift your own

Dr. Chen Really loves what he's doing. His lectures on AI topics blew my mind away. Thanks to that I'm now teaching myself to code. He also encourages you to develop a lifelong study habit and set a good example himself. The class requires a lot of work but I'm learning twice as much as I did in Calculus 1.

Dr. Chen is hard to follow sometimes, but if you go to office hours and take advantage of all the resources offered to you, you will succeed. I really like how he is ALWAYS available to answer my questions.

Dr. Chen is really passionate about math and genuinely wants his students to learn. There's a lot of hw and u really won't be successful unless u go to lecture. He tries to include relevant examples to make it more interesting. He's super helpful during office hours too.

I got a 40% on my first test and almost dropped the class but finished with an A. Getting used to his teaching style is tough at first, but he offers a TON of extra credit and help outside of class if you're willing to work. Dr. Chen really is a good guy and wants you to do well but you have to show him you're willing to put in the effort.

Great professor! He cares about the students and is willing to talk outside class when I drop by. He gives honest but good advices about my career and life. My one regret was that I focused more on my other classes and not enough on this one.

Dr. Chen is the most inspirational professor I've had thus far at UWL. While he sometimes got off track talking about AI and extraterrestrial life, it was usually totally mind blowing and made me more eager to learn. He's not the easiest professor but I would recommend him to any one majoring in something math related.

Great Professor. Very systematic and well organised lectures. He grades the material very quickly. Extremely helpful in office hours. Quizzes are exactly like the homework and the tests are the same as the quizzes. One of the best professors I have ever seen.

Dr. Chen is hard to understand sometimes but overall I thought he was a good lecturer. He talks about different interesting applications, but you never have to know them for the tests. He gives a ton of bonus points for problems out of the textbook and they are definitely worth doing. Majority of grade is 4 tests and the final. No graded quizzes.

I hate math, but I loved Dr. Chen. He's super funny for a math professor and passionate about different applications. Lots of bonus points available. Tests are ridiculous, but he curves if everybody fails. Inspirational lectures and overall just a fascinating guy. I wish I had taken him for previous math classes!

He's very good at motivating the class. He cares about every individual's career. He manages to relate almost all his lectures to interesting modern topics like AI. He moves at a fast pace. Tests had very difficult problems that you'd only know how to solve if you took notes in lectures or did the homework (there's a LOT of ungraded homework).

Dr. Chen is an awesome professor, but not for everyone. It's a hard class, so you have to work for your grade. Dr. Chen is very passionate about math and will often talk about AI or his research (super interesting!). The class consists of 10 group projects, 4 exams, homework, and the final. He also offers a lot of extra credit. Take Dr. Chen!

He's a great professor to have, always willing to talk with students after class about homework questions or anything that crosses their mind. The best math teacher I've ever had, but still made me work for my grade in the class.

This class was tough but you can get the grade you want if you work for it. Explanations in class were at times hard to understand, but he really does do his best. ALWAYS helpful when student's have questions, and begins every single class asking if we have any questions to go over. It's not easy, but he is a good professor who really cares!

It is a hard class, but Dr. Chen is very passionate, and sometimes teaches about things outside of the class, which is cool to learn about. The grade is 80% tests, which is pretty tough. Textbook homework is optional, but I suggest you do it, it helps a lot with the tests. Also, do the bonus problems, they help your grade a lot.

I love Dr. Chen, he is so smart and clearly interested in math and its capabilities. He is very open to answering questions during and outside of class. Basically gave us all a 100% on our Exam 4 because it is graded upon completion to help bump up our grades. He is funny and makes a boring class fun. I definitely recommend taking Dr. Chen.

Dr. Chen is an overall great professor. He shows great care for his students. Bonus points are applied to exams, and they are easy to earn. Math has always been easy for me, so I tend to get bored in class. However, Dr. Chen kept me focused and "entertained" the whole time. I would recommend for anyone who needs calc in college.

Be prepared to work very hard and study long. The exams are quite difficult but Dr. Chen is extremely smart and passionate about the subject. He will alter the whole lesson of the day to the classes needs. Great professor.

This man will show you the truth, he is the key.

Chen's lessons are pretty difficult and it will take a lot of studying and hard work to get a good grade in this class. He is very smart but can be difficult to follow in lectures. Although, he is very passionate for what he teaches and has a lot of knowledge he is willing to share if you are open to learn and ask questions.

Dr. Chen is impossibly intelligent. He always asks if anyone has questions at the start of class, is an engaging lecturer, and is passionate about Calculus. However, he also teaches super fast from memory, which results in needing to study and learn a lot on your own to understand what's going on. He gave 100% for the fourth exam to boost grades.

Dr.Chen is simply the best for calculus. His lectures are beyond textbooks and equations. He clearly explains the practical application of everything. It is always fun to attend his lectures. Further, the bonus questions help maintain a good grade. He is very caring and clears questions at the beginning of every lecture.

Dr. Chen is one of those professors you either like or hate, and it is easy to tell on your first day of class. In my experience, he teaches content fast and very well. He clearly explains the functional application of what we learn. Not only is he hilarious but he also offers a LOT of extra credit. If you want to challenge yourself, pick Dr. Chen!
