Han is a very nice professor and his teaching style is awesome. In the beginning, he went fast yet he improved his teaching greatly ever since he asked us for feedback. He was willing to help and answered your emails quickly, even during weekend. He also clarified hard concepts efficiently. I am happy to have him as my first college math teacher.

Great professor! Extremely helpful and understanding towards the students. The assigned homework was relevant and helpful in learning the material. Sometimes there were a little too many problems though. As the term went on I understood more of what was being taught in lecture because Han slowed down to meet the students needs.

Very helpful professor and tests are kind of easy. However, his teaching sometimes lacks examples and difficult to understand.

He is the best professor in the world!Extremely caring and he would do his best to help students get a good grade. I totally recommend him, he is such a nice guy. pretty easy grader his exams are easy and the hw assigned is pretty helpful. He is the best! He made me love math again!

Very good teacher

Very helpful Professor. He showed us many many examples in detail and gave us some quizzes for practice. HW are assigned very carefully without repeating too many problems. Questions are very relevant and helpful for understanding the theory. Final exam are hard but with bonus. Grading are very fair.

He is a really good teacher who simplifies everything down so that you can understand the basics and then get good grades on his quizes. He is eager to help anyone who has a question as long as you ask

very good

Qi is an outstanding teacher. His lectures are clear and easy to understand, he provides detailed examples of all the materials covered in exam, and he is easy to reach out to for additional assistance if need be.

Professor Han made things easier to approach and understand, with some very relevant homework questions and in class quizzes. He also gave 2 tests which enforced the key topics for the final exam. He is very helpful and always answered your questions. Recommend him.

I loved having him as a Professor. He really cares about his students and encourages them to attend office hours for extra help. His homework assignments properly prepared me for his exams & final. Notes are easy to follow and it helps that he posts them online after each lecture. Wish he was my professor for calc 3 and 4! Would strongly recommend

He is overall a good professor. I liked the fact that the homework, the quizzes and the test reflect the things that we have gone over multiple times in class. Easy class yet super helpful.

He is very understanding. Overall he is a good professor and he cares for his student. He also frequently asked us to asses his teaching style. So I think he is someone who listens to his students and looks out for their best interests. He is reasonable person to talk to in terms of grades and any sort of concerns related to the class.

Professor Han is excellent. He is clear and thorough explaining the material in the lecture. His notes are well organized and available online and the homework he assigns is relevent to what you will see on the exams. He is very willing to answer any questions in the lecture or in his office hours. I would choose him as my professor again for sure.

Professor Han is an excellent teacher. He explains all his examples in full detail so you understand. Also all work learned in class and through the homework accurately showcase what were on the quizzes and final exam.

Qi is a great prof. Knows his class and knows they do not want bs. Teaches to the class not just from the book and does a really good job.

He is an exceptional professor, very invested and enthusiastic in helping students learn. His mild accent did not inhibit clarity for the most part. He always listens to students suggestions and requests and works hard to make the class work for everyone. Very fair assessments. Friendly guy. WOULD DEFINITELY RECOMMEND!!!

Prof. Han is an excellent professor. I really enjoyed his class. The way he sets up the class makes it easy for a student to be rewarded for hard work and persistence. The final was tough but I still got an A. With Prof. Han I feel as though anyone who puts in the time will be successful in the class. I would give him my very highest recommendation

Good guy, but class is very cursory and boring and he does not properly explain the concepts for use in later mathematics classes. Easy A but would not recommend for students who actually want to learn new math.

I would definitely recommend taking a class with Qi. He teaches well and I'm fairly certain he is a certifiable genius. He is also humorous. All around great experience with this Professor.

Professor Han is a fantastic professor. He teaches math in a very efficient and understandable manner. It may be difficult to understand his accent, but you will learn a lot. No tests, but weekly to biweekly quizzes that are two or three questions. Pay attention in lecture and it will be an easy A.

Han is the man. Class is very easy to get a B and if you put in a little work can get an A. Quizzes are very easy, once a week or two weeks, and there are only 4-5 HW assignments total. Final is challenging but not impossible. Take this class if you can

He's a great professor. It's too bad I wont be having him for Calc IV.

Dr. Han is a very generous and fair professor. He drops the lowest quiz and homework grade (theres about 5 of each) and gives several bonus questions, so it is very possible to maintain a high average until the final. He is very clear on what you need to know for the final exam and is very willing to spend more time on topics if its needed.

Han is very helpful, he'll make sure you understand the material before he moves on if much of the class doesn't understand. Also keeps it lively. Good prof.

Professor Han was very helpful overall. He used a lot of examples in his lectures, and he gave only one homework assignment per week, so the workload was very manageable. His quizzes were also much easier than the homework, so if you can do the homework, you should be able to get an A. Would highly recommend taking Calc 3 with him.

Professor Han is a great teacher who tells you exactly what you need to know to do well in the course. He cares most that students understand the mathematics as opposed to showing them long and drawn out proofs.

Need to work more on pronunciation!

Great prof. Inspired you all through the semester. Never skipped a single class and fight for pass - it seems my hard work paid off with a B Would recommend him and surely take his class again...

Professor Han is a very good teacher. Depending on you math background, the class could be easy or difficult. He has an accent that can bother some, but I was able to understand him. A large portion of your grade is based off of the final. Doing practice problems from the book is a great way to study for his quizzes and the final.

Interested in providing his students with the most important aspects of the curriculum to underline the necessities and put less focus on the useless points that the syllabus requires.

Very clear, fair grading

This is my best math class ever and I really enjoined it. The course was taught very clearly and the notes were neat and updated online that were so so so helpful, you won't even buy the book...I am not really good at math but this time I am really into it as I do not have to do long, boring computations. Strongly recommend and take calv with him

He's great. Nuff said.

wonderful guy and take cal4 with him. To be continued...

Prof. Han is an amazing professor. His lectures are good, although most of the time I felt the need to look for additional help after the lecture (my Calc background was not good, though, so that may not be your case). Most people could get around a B in his class, and probably an A if you have a good Calc background or already know the stuff.

Professor Han is direct in what he expects from his students. He gives you a straight-forward guideline of what is important for tests, and what he is teaching for theory and understanding. He asks if you have any questions, and will do his best to answer during lectures. Otherwise, he will tell you to talk to him after class. Awesome teacher!

Professor Han is a very good teacher. His lectures are clear and to the point, but he is always willing to answer questions too. I did very well in the class with a very reasonable amount of work. He often tells you what is on the quizzes or at least hints. Definitely, do the homework and don't leave it until the last minute.

Qi Han is a god. He makes it his goal not just to teach you, but to make sure you learn the material. There are only four quizzes and homeworks per term, so I never felt overwhelmed.

This guy is the man. Great teacher. Really understands how to discipline the students indirectly.

Explains everything well, though some may find notes to not be straightforward enough. Ranks topic importance for the final. Gives plenty of examples. Tries to make himself a better teacher-takes suggestions seriously. Is a happy person. Straightforward tests, with the occasional repetition of a hard problem from HW (due weekly). Great teacher

Qi Han is the best calculus teacher I've had at this school, however the class was difficult as Calc 3 is, so it took a lot of work.

The class is hard but the way it's given is very inspirational with many 3d graphs - it simply makes you understand, think and work to success. Prof Han is very nice and helpful, and hef an interesting person like a cowboy, I feel... Be careful though to listen - even he put his notes online everyday, he also presented different things in class.

He's very clear when explaining things. He gives so many examples and how to work through them. He tells you what the test will be like and the topics on it so you can be more prepared for it.

Qi Han is a very good professor. Lectures helped teach material and he is actually kind of funny. He asked us to rate him on here which shows he wants to be a good professor and wants to improve where he needs to.

His lectures were very good, a bit hard to understand at times, but the course content was well explained.

Professor Han is the BEST Math Professor I have had at WPI. He cares a great deal about the success of his students. He truly wants you to succeed and gives you all the tools to do so. If you attend lecture, pay attention and take the time to learn the fundamental concepts behind what he teaches, you will earn an A. He is helpful and hilarious!

Lots of examples that are easy to follow and make the material easy to understand. He won't let you fail the class so as long as you do the work you're guaranteed not to NR. I would definitely take this class again.

Professor Han was an amazing professor! He goes very in depth with concepts to make sure you understand them, but he doesn't just hand you an A. At times he'll give you exact questions from the exams as examples so it's recommended that you go to lecture. Also, do the homework to further understand concepts, it's really helpful! Would take again!

Not a bad course. Pay attention in class and you'll ace the quizzes and tests.

Awesome teacher, condenses the text and the syllabus to its essentials, assigns only what is absolutely necessary; very fair grader who gives lots of partial credit. Makes jokes in class occasionally. Cares about the application of the mathematics he teaches.

Once you get past his accent he's a really good professor.

Took MA1023 and MA1024 with him. Clearly explains everything. Feel free to go talk to him after the class with any of your queries. Encourages communication outside the class (like in his office hours). Willing to go over class material again if you have any problems. Pay attention in his class, do well in his quizzes and you should be all set!

Master Han is the man. He cares very much for his students and their success, is always happy to answer questions, even from the dummy who asks the most obvious ones - and always respectfully. Kinda feels like we're his children. Excellent, excellent professor. You'll work, but you'll know the material cold when the term is over.

Qi is an incredible teacher. He was able to take an intricate class such an the Calculus of Variations and make it into a beautiful journey of mathematics. I highly reckon anyone to take this class, really opens your eyes up to the power of mathematics and calculus.

Prof. Han is someone who really cares about the subject he teaches and the students taking his classes. He encourages any and all questions and stresses understanding over grades or straight memorization. If you go to lecture and pay attention, you'll do fine on tests and homeworks. You might even have fun.

The class content was difficult, but assignments are easy as long as you take lectures. Exams were based on assignments and lecture notes. Han is a really helpful teacher.

Good course, prepare you for the graduate course

Can't say enough good things about Professor Han! He was clear with course objectives, understanding about material we needed to cover, and helped us with anything we didn't know that would help us do better in his class.

Good guy, there to help and solid grading system. Makes you work to learn the material by assigning a targeted number of homework problems that will best help

Dr. Han is a riot in class. He discusses his policies frankly and honestly, and offers all the assistance he can to his students. The course is straightforward. Study, and then pass.

It took me about a week or two to see the logic of Dr. Han's teaching and after that everything goes smoothly and almost perfect. His is really inspirational and ready to answer your questions whenever you ask him. I would say do the assigned work carefully and use his office hours effectively then you are surely safe.

Professor Han is a great professor and his lectures are very straight forward. He puts notes online and chapter summaries that will tell you exactly what kinds of problems will be on the test. The tests are exactly how he says they'll be, there are no surprises. If you put the work in, you can get an A.

Han is a very nice person and a great professor who knows the background of his students and how to adjust his teaching. The material can be hard depending your experience with matrices, but he does make things easier to be understood. 2 tests and 4 HW and quizzes. Extremely helpful online notes, solutions sets and chapter reviews.

He's an awesome teacher. Sometimes hard to understand, but he wants you to do well and makes it easy for you to do so.

Amazing professor!!

Excellent professor. Really tells you everything you need to know for each test and quiz.

The first part went really slow - 2 weeks on row reduction. That could be good for those who did not know matrices before. After that, I think everything went smoothly and Han explained the motivation and application clearly, especially about the eigenvalue problems. I particularly liked his color coded way in showing matrices multiplication.

Good amount of assignments, doesn't go overboard on assignments like other introductory math professors. Last test was a lot harder than the rest of the material.

Professor Han is amazingly understanding about the rigor of most college courses, which makes him very easy to talk to about grades or questions. Also he doesn't want to have to give out anything less than an A!

I would take his class again. Sometimes hard to understand, but he is a very good teacher and by far the best Calculus 2 professor at WPI

He is a great professor and prepared me well for the final!

4HW, 4QZ, 2Tests were all you needed. QZ straightforward, Tests hard, the first HW was big - 30+ problems about row reduction and solving linear system of eqs with lots of computations. He taught most parts clearly and pretty laid-back, and used cartoons sometimes - the class was fun. He asked us for feedback so he cares about his teaching.

My favorite math teacher at WPI. I like his teaching style and cannot recommend him enough. Do the homework, go to him and ask questions and you will master the material and succeed.

He gives lots of examples and extra credit on every quiz and test. He barely has an accent, you can understand him perfectly. He asks for feedback a lot, he really wants to make sure you're learning and understanding. Absolutely amazing professor

PROFHan is a great person and teacher! The mathematics was taught clearly, and the class was a lot of fun as he made jokes or presented the material using graphs or cartoons. The quizzes and tests are hard, but most the topics were shown either in class or via HWs. Pay attention and you will do well. I will follow him to cal 3 next term :-)

It was a great class and Prof Hen did an amazing job! He really cares our learning and did his best to help us. He taught the material clearly, warned us frequently common mistakes and explained the connections of college math courses, and always gave us interesting bonus problems. My only complaint is about the HW; otherwise I really love it

Han is a great professor. His quizzes are straightforward and many of the exam questions are taken directly from the quizzes. Only complaint is that I had him for Calculus 2 and he didn't teach us many of the topics that were on the Common Final.

Great professor, beautiful class, difficult material, reasonable tests. Professor Han is always ready to help as loon as you ask or visit him in office hours. Made me ready for cal 3 4 and will follow him in C term. He should go easier and strengthen less topics in the future, but I like his teaching style and class organization very much

Qi Han is super cool. Not as good at teaching calc 3 as calc 2 in my opinion but he's still a good professor

The guy knows what he is doing and is compromised to getting you to learn. He can be very funny and although he has kind of an accent, he is understandable and easy to follow. Will help as much as he can and is a fair grader, shares his notes after every class.

Dr. Qi Han is always there for his students. If needed, he makes himself available outside office hours to help any student who needs it. He assigns homework on each section covered in class and then weekly quizzes that replicate the homework. He has an accent so it's hard to comprehend at times but he's always willing to explain things.

Best professor ever. If you want an A, go for it. All the class about is calculation, not too much definition, no reading homework. The test is easy enough if you can do all the stuffs on notes.

There will be homework, but less than many of the calc teachers. His lectures are occasionally a bit tough to follow, but if you keep listening things usually get cleared up. He's generally friendly and tries to be helpful. Passing the class is very straightforward - if you understood the homework, you'll do well on the tests.
