Hard to understand, speaks with strong accent

Horrible accent, mumbles most of the time, inaudible. Completely unapproachable, no better in office hours either. Tremendous amounts of required homework for grade, ~10 hours per week easily. I tell all students to avoid him like the plague!!!

don't take any of his course... it is very difficult to understand him... and he moves quickly

Most students drop rather than endure this professor.

Unless you are a sadist, you should take another prfessor.

he tries hard to help you, my tests were given off the homework assignments, same exact questions, but he pick the hard ones. other than that, his accent kills, and says "TRICKIES" a lot, i think he meant tricks

This professor is soo hard to understand! I can't follow him too well. If you are just naturally not good at math, you probably won't do good in his class. you basically have to teach yourself the material.

He doesn't teach you anything he just writes on the board and says "lots tricky".

Lectures consisted of him copying the examples in the book onto the board with little explanation. Rarely looked at the class and would say, "If no questions, we'll move on" ignoring students with their hands up. Plan on teaching yourself calculus if you take him.

SUCKS!

SUCKS!! I took this class in the spring time. I got a lousy c+ out of it. Most the class failed the first and second tests. By the end of the semester only 9 or so of us remained. Now, that is just bad teaching. Couldn't speak English, was not helpful, and wore sandles with socks. Now I know that has nothing to do with math, but it bugged me!!!!!!!

Took during Summer Session-Exam questions directly from HW, study and you'll be alright. He isn't very helpful, and even is condescending if the class has difficulty comprehending a concept, etc. Thick foreign accent difficult at times. With a large dept. full of a variety of professors, I'd look elsewhere.

Horrible teacher, but easy class if you study. Show up for the quizzes, but if there's none, then just sleep. Heavy accent, he says refraction instead of reflection, and amplititude instead of reflection, among other things incorrectly. avoid

Asked teacher to write out steps he said no, went too ask him question and told me it was not his office hours. I told him thatI had a class during his office hours and he said he couldn't satisfy all his students and sent me on my way.. Test is from hw. but there is alot of hw. Accent is there not bad its his attitude of not wanting to help.

TERRIBLE TERRIBLE TEACHER DO NOT TAKE HIM!! HE CAN BARELY SPEAK ENGLISH AND IS RUDE TO ALL OF HIS STUDENTS! DO NOT TAKE HIM!

He is the worst teacher I've ever had. His exams are ridiculus and he is relentless on the grading. He will even take points back from an exam if you go up to get more points and he finds something he thinks isn't to his standards. No joke, he is a horrible teacher. The funny thing is, he likes that most fail. I couldn't say enough bad about him.

teacher does not clarify anything. lectures are completely useless. he explains things in the most difficult ways when there MUCH easier ways to show the solution. which makes the student have to go and teach themselves calculus. only useful thing about this class is the TA. AVOID AT ALL COSTS. DO NOT TAKE. he has 50 percent fail rate.

If there ever a worse professor I'd be quite surprised. I read a previous post where somebody said he seems to 'take pride' in failing students, and it is pretty accurate. I'm re-taking with another professor, and no exaggeration: I learn more in one lecture then I did an entire semester in his class. AVOID THIS PROF!!!

Horrible is an understatement. I took him over summer session one, and with every new topic he said "if you don't understand this you won't pass" but he would never directly answer questions directly. He gave three tests, and let's you use a sheet of notes but 7q's 15 pts each. Impossible.

Hard to understand. Does not explain what he's doing, instead he solves each problem on the projector and you just copy down the steps, but you don't know why you're doing it. Definately a lot of self motivation and outside study to understand anything.

If you do not have a strong math background then DO NOT TAKE THIS PROFESSOR! Yes he has an accent, but the accent was not the issue, it was his inability to communicate properly with the class. He sits on the doc cam working examples problems from the book and every 20 min or so he looks up at a sea of confused faces and continues regardless.

This teacher is not the greatest teacher to learn from. I took him for summer session 1. His test are based off of homework problems and choses the harder problems from each section. Make sure if you don't understand it you get a help because they'll be easier to understand than him. He teaches you from the book and he goes over the material quick

Sits by projector and copies notes straight from textbook. He is too smart for everyone and has a heavy accent.

Jichun Li is a bad professor. I used to love maths, but not with him. He should be your last option. The way u can make it through his class is by doing all the homework he gives, which are a lot. Do your homework with tutors. There are 4 exams, and everything comes from the homework problems.

He was a terrible professor, and continually told students that they were going to fail. He was not kind, and also did not follow the disability resource center accommodations.

Dr. Li is by far the worst professor I've ever had. Exams make up 80% of your grade, while homework, quizzes, and attendance contribute 20%. His idea of lecturing is copying down theorems out of the textbook (which is filled with typos) and speaking into the whiteboard. His TA's explanations were horrible as well. Exams questions come from homework

Real teachers do the following: present the material, teach the material, grade the material, and continuously assess this as a process to discover if the teaching and/or the learning is working. Some teachers, the ones to avoid, like this 'teacher', fail at one of these. Jichun fails to do ANYTHING besides presentation. PDF's alone ! teaching.

I understand that the pandemic makes teaching hard but this class was honestly the biggest joke and waste of time/money that I have ever had to deal with in university. The only good thing about this class is that the tests were based entirely off of the homework so if you did the homework you had the answers. Learned absolutely nothing though :(

This professor is a complete joke. He reads from directly from slides and won't respond to questions from students. The only thing I learned in this class was how to watch $1000 go down the toilet.

Never in my academic life, have I felt like I waste so much time in school. The language barrier is a real problem. He does try to explain as best as he can but I didn't want to hold the class back or embarrass him. HWK is due too soon (3 days). The Gilbert Strang textbook is too advanced with PURE MATH questions. No application problems.

This class is one of the most that I have ever had trouble figuring out how to do HW. Reason he does nothing but copy and paste from the book. Second 80% of your grade is three tests fail one and it is over class avg below 60% will yell at the class for the failure and say that it is you fault and not his.

No online materials and lectures on examples in the book. High fail rate, not good overall.

Truly a sad sight. The average grade on the first test was a 30% and he refused to curve. He proclaimed that in the "real world" there is no such thing as a curve. He reads directly from the textbook and doesn't truly pause to add his own insight. There is 0 and I mean 0 interaction with students when teaching. An embarrassment to the teaching.

you might as well read the textbook at home cuz he reads directly out of it and blames your algebra skills for your failure. he just writes whatever is in the textbook and doesnt explain anything/works way too fast in lecture. i feel bad for everyone who isnt gonna pass cuz it took an arm and a leg for me to get an a

Awful experience. Lectures are dense and by the book, his solution if you're struggling is just to do more homework. Exams weigh hard and most fail + no curve given, and he shifts all blame to students + even the TA. Directly told us we weren't worth his time. Pretty heavy HW, all on paper, and you must ask to see your grade. Miserable all around.

Professor Li should be your last choice for Calc 1 if you don't already have a very strong background in math as he rarely backtracks or slows down to do a review on the algebra parts (which are usually why the concepts are hard to grasp). There were two exams and one final but bombing anyone would be hard to make up. He was also very demeaning.

Not even done with the course and I already had to drop. Terrible instructor, made it clear several times that he would rather teach his PHD students rather than "waste time" teaching us. Asked about grading on some exams and he told the class of 50 students that we could go buck fuffalos. this can be corroborated by the entire class

Does a terrible job explaining everything and even if you ask a question he will direct you to the TA. He is incredibly difficult to understand and does all work on a projector, be ready to tell him to adjust the paper every 30 seconds because it will never be on screen .

Jichun Li is at times degrading to students. 30 students dropped his class when i took it because of how challenging he was making it. exams have few questions, he allowed a sheet but never really explained concepts. Blamed his TA for his shortcomings.
