This is one of the worst teachers I've ever had he's not clear all he does is examples from homework doesn't even show you how to do the work he often steers away from lecture to show different material not even relevant to the one at hand I don't know he this guy got good reviews I can't understand him at all.

Funny thing is that I was actually looking forward to taking this class. However, this guy is a terrible instructor. He goes off topic frequently and appears as if he doesn't really care for his students. 2/10. Would not take again.

When he teaches its more like teaching the board he is writing on... except it isnt even teaching, just talking about what he is doing without any sort of clear explanation. He doesn't even introduce sections that he is going to lecture about. He just jumps straight into a example that is very tough to follow. SELF STUDY. WOULD NOT TAKE AGAIN

He tries to help but fails miserably at it. He doesn't know how to explain or clarify, he just tells you the answer. His lectures are so dry, he just recites from the book and his accent doesn't help. If you value your grade dont take him.

do not take so hard his class

Ratings speak for itself. I thought I could self-learn everything, nope. Avoid taking any of his classes.

Extremely confusing, doesn't answer questions too well either. Makes concepts much harder than they should be. LOTS of homework that he collects. Tests are quite hard, as were the quizzes.

I always thought studying result depends on our efforts, not professors until I took him. He knows math, but he definitely doesn't know how to teach it. He can barely explain the concept, which he uses only the last 20 minutes of the 2 hour class to explain. He gives a lot of homework, but the tests are different and super hard.

If you're not an expert in Math and want some real challenges, then take him. He will show you the true meaning of desperation. Tests are tough, which are not related to his short instruction and homework (a lot).

His accent is EXTREMELY thick, he talks very quietly and his hand writing is SUUPER small and illegible. He dedicates a good portion of class to questions, but what use if there if you can't understand him. At least he doesn't collect homework very often according to his syllabus.

take this class if you want to fail, you will not learn from lectures because his accent is so strong, his quizzes and tests are very hard with only one problem based on homework, he does not give extra credit TL;DR : DO NOT TAKE THIS CLASS

After 2 or 3 weeks, a third of the class don't even bother to attend his class. Classes are EXTREMELY boring. Requirements: Approximately 2 hours available for doing monotonous and repetitive homework. DAILY! Patience, you will need a lot. Math 22 is not hard. Do the homework and study alone you will pass.

His in-class speeches are confusing and unclear. I do not recommend this professor unless you are already good at math and do not mind learning everything on your own. Does not teach from basics point of view. I don't think his teaching style was helpful in teaching anything new.

Shi isn't the worst. Take him if you are an independent learner and good in math. He lectures to the board. Spends most of the lecture explaining how a formula is derived, and then 10min on 2 example problems. Blindly gives homework problems 5min before the end of class and a lot of it. Unclear on the work he expects on tests. He is smart though.

I would avoid taking this professor if possible. His accent is very thick so it is very hard to understand him and he speaks too soft for anyone to hear. He has a habit of standing in front of the board when he writes so we have no idea where he is and soon after, he erases it before we can finish copying. many of us are forced to self study

Half of the students dropped this class but the professor thinks is doable because one student got 100% in the last midterm. Tons of homework that does not help on the exams; way harder questions tested. Good luck taking his class.

He's a nice prof however you can't understand what he says which makes it difficult to understand the material and follow along. He solves hw problems in class without really explaining. I had to drop the class. I would not recommend taking him.

I took his class and had to drop it. I was having a difficult time taking notes in his class. His back was faced towards the students for a majority of the time and I could barley hear him talk. He was very unorganized in his lecture which also made it difficult to take notes. On top of all that, he assigns a ton of homework every day.

This professor does not care about his students and does not make the time to help students when they need it the most. He assigns so much homework each day and should just replace the textbook with Webassign. While explaining problems he would constantly make mistakes and wouldn't even notice until students would say something. Don't take him.

The majority of students that seemingly did well in his class were students that already knew the material. He approaches teaching as if he was just reviewing on what everyone should already know. Not great. Doesn't answer questions very clearly and your better off self-studying. If you ARE good at just doing the chapter at home then you'll be fine

very very very bad at teaching, if u already know the material you will be good, but don't except learn anything from him, most time he just reading the definition from the book, if he didn't finish the chapter, he will just tell u go study by yourself, also very bad explanation for HW.

this last test was horrible. I dont see myself learning in this class and I dont recommend him because lectures dont address items on the test much

Teacher does not address anything in class and reads right out of the textbook. To top it all off, his tests have nothing to do with his minimal teaching. To be fair he does give out practice quizzes before quiz days, but it does not prepare for the test at all. I do not recommend this class.

This professor is absolute trash. Ridiculous amount of formulas to remember, goes through chapters like nothing, reads straight out of the book, redirects questions instead of answering. WORST.

Didn't learn anything. Extremely boring, and tough grader. Wrecked my GPA. I dont recommend him

the worst professor! worst explanation! you just study by yourself! you need to spend at least one hour and a half every day on his homework! DO NOT TAKE HIM

messes up often on in-class examples and when he does not mess up on examples, he explains them poorly. literally reads straight off the book for lectures. You NEED to spend multiple hours each day doing homework to keep up with the class. Average test score for first midterm was 54.5% and only 2 people got above 80%. avoid if you can!

Took him last quarter, and he was honestly one of the worst professors I ever had. He mumbles alot, lectures are brief and very vague, and he's prone to a lot of off-topic ranting. Homework is very long and tedious, not much point to it since he's so vague when it comes to teaching. Avoid this guy at all costs

Very bad professor, avg in his class this semester is around 50-60% for tests and quizzes. Lecture is 50 min, but spends half the time going over hw problems and the actual lecuture being 20 min. Talks very quietly, hard to understand and expects us to around understand concepts the very next day as he moves onto the next lesson. Pls pray for us

He literally reads from the book and says what he writes. He doesn't explain anything at all. He spends more than half of the class time going over homework problems while making mistakes along the way. A section of homework is assigned each day, all due on midterm days. Midterms/quizzes are based off homework problems. Also a tough grader.

Worst professor EVER, not even exaggerating. Reviews questions from homework and writes out examples from the book. Tests are hard, class in boring, and his lectures are pointless.

Absolute historic worst, by far. Doesnt really teach such a difficult subject but skims through and expects us to understand. Class average for midterms varied from 50%-60%. This was a bad decision.

Just a lazy teacher who doesn't really want you to succeed. Doesn't have a canvas page, so you don't know what your grade is, doesn't bother explaining, and is very test heavy. Makes office hours inconvenient

Probably the worst math teacher Ive taken at de Anza. He grades test hard for no reason. By the second test was due more than 20 people dropped. Homework is somewhat a lot to do and he grades the homework hard as well. He teaches straight from the book so its like teaching yourself. I highly recommend taking another teacher anywhere else than him

I took this professor over the summer and he is by far one of the worst teachers I ever had. He literally gave everyone in the class the study guide a day before the midterms. The majority of the class dropped and the average for every midterm was under 65%. He's nice but he can't teach at all.

DO NOT TAKE THIS INSTRUCTOR. ABSOLUTELY DO NOT. Even if you think you are smart enough to pass. The way he teaches cannot even be called teaching when all he does is point at stuff at the textbook and read it, then proceed to "solve" problems by just showing well "this is this so it becomes that" without even explaining the idea and the why.

He is a nice guy but isn't great at teaching. He has a strong accent and doesn't talk that loud so you can barely hear him. Don't risk taking him

Don't waste your time, trust me. Never take his class. He won't give any credit for your efforts made in any problem during the exam. Hard to understand, reads right from the book, which makes no sense. Any amateur student can teach like him since you just have to project the book's pages on the screen and read what is written. WRONG CHOICE!

I made a mistake of taking him for discrete math. He only reads from book, gets confused by his own calculations, doesn't explain anything, gives a ton of HW that is worth just a few points, his exams are difficult and you basically need to study only from the book. Oh and his accent is very thick and he skips words from the book he can't pronounce

This is honestly one of the hardest classes Ive ever taken at DeAnza. There is no point of showing up to his classes because all he does is read from the textbook, which anyone can do. He doesnt really do much explaining on examples he does in class. This class is pretty much self taught. Gives zero to no points for even attempting a problem.

Took his class online in Summer 2020. Dont take his class if you want to watch his "lectures" which are just him going over examples without explaining the context. You basically have to read from the book & teach yourself. Just 3 quizzes, 2 midterms, and final to be graded on. He doesn't even post your grades on Canvas so you never know what it is

Shi is terrible (at least online) for anyone considering him. I've heard horror stories about profs who don't do anything but send quizzes and tests but that was this guy. Didn't know how to use canvas. Would only give a grade, but never let you see what you lost points on quizzes/exams from for sure. Was forced to take him - avoid if you can.

Do not take his class if you want to have a horrible grade. Exams are very hard you wont have a good grade. He also doesnt know how to teach only let you read those useless books. JUST DONT TAKE HIS CLASSES

His lectures are basically reading from the textbook with even worse explanation. You are better off reading the textbook and self-study. He made up all the questions for the quiz/exam so doing the homework is pointless. None of them are related to the homework. Grades are not posted. Avoid taking him at all cost no matter how desperate you are.

He's a really tough grader. If you miss a step in your work, you lose points. Grades are not based on the correct answer (typically given a point), but if you got to the same step as the professor. Literally average test and quiz scores were DD+.

Regret taking this professor as he doesn't teach the class well enough with his pre-recorded lectures which is him reading off from the textbook. Doing the problems and watching the videos won't help much as you're better off teaching yourself. His exams are difficult, so please form a study group and seek all the help you need to get a good grade.

Wow. Never have I had such a bad professor. I have always been an A student with 16 plus units. Horrible old lectures from previous classes - very lazy. Unable to reach him. Just says read the textbook. Homework way harder than any problem he covers in his lecture. I wish I listened to the reviews and stayed away from him. Please do not take him.

Shi might be the worst teacher that have ever taken in college so far. His exam are super hard for no reason, His lectures does not teach anything . But it might be helpful to watch the since he puts some questions from the lectures in the exams sometimes. If you can avoid taking his class, i would advice you to do so.

Please avoid taking him at all costs. Not only does he can't teach, but gives you some of the hardest problems on the quizzes and exams which is nothing you've ever done on the assigned homework problems or seen in his pre-recorded lectures. He also grades them in his own way. This is where you'll lose most of your points and score really low.

don't waste your time with this class in an online format. Maybe in person is better, but the online class format is the worst of any class I have taken and it isn't even a little bit close.

This class online is one of the worst things you could do to yourself during corona time. His grading is super harsh and his tests, especially the final, are 20x harder than the homework. His lectures are all prerecorded from June 2020 and contain some information, such as test time, that is outdated. DO NOT TAKE THIS CLASS IF YOU WANT A GOOD GRADE

He might have been okay in person, but he is horrible online. Tests don't match homework or lectures, which are prerecorded and straight out of the book. He puts minimal effort in and expects 2 hours per weekday of effort in return, don't take him

DO NOT TAKE THIS CLASS!!! He offers NO office hours, his lectures and handwriting are incredibly hard to read and understand and the class is graded purely upon quizzes and midterms. There is no homework for grading. All of our exams had F averages and the professor blamed us for them. Taking his class was the worst mistake I've made.

I had to take this professor as a last resort - worst decision EVER. No office hours, no feedback on tests, you can't see your grades on Canvas, he emails tests late but expects them back on time. Lectures barely relate to tests (if you take him, be prepared to self-study). He's very sweet but the class is too unstructured and disorganized >.<

Terrible professor for hard math class. I didn't understand what he said. l would never take his class again.

It's absurd how Kejian Shi is still employed. He doesn't teach, only shares recordings of his own lectures which barely covers the material, aside from his very thick accent. You may be able to get an A from him, but he curves so dramatically that don't be surprised 60% is an A. In general, lots of hw that he never marks, awful lectures and more.

The worst professor I've ever had at De Anza. He's the sole reason why I wasn't able to get my associates degree in time to transfer. If you have a choice, DONT TAKE HIM. I didn't listen to the other people here because I thought it would be fine, but its not. The only way you'd be able to pass is if you only had 1-2 other classes and no job.

He has 1 year old youtube videos he posts on Canvas where he briefly goes over the section. His videos are so useless he even mentions in one of his videos about getting single digit clicks with two sections of 30 students. Awful professor he was the only choice I had would avoid at all costs.

The worst professor I've ever had bar none. No office hours available, lectures are unhelpful, and tests and quizzes (which are the only thing he grades on) are significantly more difficult than any of the lecture problems or homework he assigns. You still might be able to pass because of the curve, but it's not worth the stress, avoid at all cost

Do not take this teacher, you will not know your grade bc he does not know how to use canvas, he's test/quiz are the hardest thing ever, and that's all he grades and the time limit does not match for the amount of questions he gives, how can u learn when he writes so sloppy. He won't answer questions.

Easily the most painful course of my college education. If you want to learn discrete mathematics, don't take Dr. Shi. Lectures consist of him dictating what he writes on an iPad, with little elaboration or clarification. The grade is based entirely on exams, which place heavy emphasis on seemingly random topics not emphasized in the lecture.

Professor Shi was a mixed bag. He does not hold office hours, does not give feedback for his grading, only grades based on 6 exams, which have topics that are never outlined in given homework or lectures. Despite this, he does curve and replace lower scores if you improve, and his lectures are not half bad. You will not be tested on what you learn.

If the cursed offspring of a sloth and a snail decided it wanted to become a professor, this is how I imagine it would turn out. The lack of energy and fumbling, plus the unclear handwriting and seeming indifference to everything... On the plus side, a recording of his lectures would probably be great for those suffering from insomnia.

This teacher speaks so slow in the lecture video. Even though I play the video in 1.75x speed, it's still slow. I really can't concentrate on his lecture because of his boring teaching style. Also, he doesn't speak clearly, which makes me hard to hear what he says. Besides, he doesn't provide exercise for students. Tests are difficult. Not recommen

It is a pity that districts have to hire someone like shi. This guy is my worst experience with any teacher in my career lack of energy & mumbling his way through crucial points of the lecture that need most explanation. Hard tests with a stab of surprises. You don't learn and struggle(a good thing sometimes) in his class, you repent. Avoid and Gl.

ABSOLUTELY THE WORST CLASS I EVER TOOK. His lectures are tough to understand. His tests and exams are 10x harder than what he solves in the lecture. He grades very strictly. Best of luck trying to get a clear answer when you email him. The only C grade I got in college. I absolutely do not recommend this class to ANYONE.

Class is "answering questions" while lectures are pre-recorded videos where he covers the most basic and simple examples from the textbook. Class average for quizzes and exams was around 50% as he would often not give partial credit and would just tell students to try harder.

Saw a previous comment and have to agree. Shame on De Anza for not firing this scumback. So unnecessarily difficult.

Limited to the first 2 weeks, but based on what I've seen so far, steer clear. All that's here is essentially an unlisted YouTube page and an email for sending tests. Anything taught is practically a trailer for the test, so you'll need to self-study. Did I mention it's a MTWRF expected lecture watch schedule? Give up on Shi or accept a lower GPA.

doesnt grade hw, so your grade relies solely on the few absurdly hard tests and quizzes. his lectures are so bad, monotone and you actually learn nothing. his writing is so messy and unclear. i actually learned nothing and dropped bc i had a 50%. his drop policy is lenient, but when ALL your quizzes are like 60%, dropping the lowest does nothing.

Lectures every day, strong accent, ineligible handwriting. Final exam is 200 points (comprehensive), out of 500 total. No extra credit. Grade based only on quizzes and exams. The class is titled intro to calc for bus, but included advanced stuff, ex: double integrals. Solved maybe 2 problems about business in total. This class will ruin your GPA.

Please do NOT enroll in his online discrete math course for the sake of your own mental health. It may seem like a sweet deal since it is asynchronous and no mandatory attendance, but he assigns 4-6 hours of homework everyday, does very little teaching in his lectures by just copying off the textbook word for word, and does not grade easily.

In my entire educational experience, I can wholeheartedly state that I have never had a teacher so incapable of doing his job. Read his reviews, and beware! I thought they were exaggerated, but all of them were true. Steer clear guys.

I took his Discrete Math class over the Summer. Not a good idea. Unrealistic time frames for learning the material. The questions on the test are intentionally complex and convoluted. There is no leeway to his grading. I have been an A student in every math class I've taken, including Calc 1 & 2. I got a C in this class. Barely. Steer clear.

Please believe the reviews you see are true, I can't believe such a bad teacher exists. He will leave a lot of homework (basically complete all the after-school practice questions), but he does not check the results, and the final grades are only related to the biweekly examination.

I took this class cuz I wanted to make my academic schedule online, but what is this? I mean what is this guy? If De Anza staffs are reading this, they should make him quit doing professor. He uses 2020 video again and again with no Info. He just reads and makes tests frekin harder. Believe me, I had A+ on Math 1C. You will regret if u ignore this.

Many students would choose this class because they would want to take it online. Don't register for this. The good things written on this website are from all by himself, and yall would know if the class starts and see his English. See the previous reputation about him. Everything is true and not exaggerated at all. This online class is a trap.

For real, this one needs to know how to teach. All he does is just read through the textbook and say do the example. He might think his class is hard which I assume he would think proud of himself, literally he is teaching nothing. He ONLY wants students to write what he wants. Even if it's far from the book. If you are seeing this, WAKE UP.

His practice exams and homework are useless for the exam. He didn't answer my homework question but he did answer me when I asked where were his video lectures are.

This may seem fantastic as the course is online, and attendance is not mandatory. However, this class is terrible. Practicing sample tests and doing homework will not help you pass your exam. The professor will not respond to your homework questions even though you did them myself, even if you just wanted to ensure that your answer was correct.

He will leave a lot of homework, but he does not check the results, and the final grades are only related to the biweekly examination. There is a big gap between sample tests and objective tests. The actual tests will be more brutal than 1000 times compared with the sample. You will not find this class easy at all.

With his exams load, the professor made you even more stressed. Videos from 2020 on Youtube are given, along with a syllabus, homework assignments, and dates of when the topic will be taught, but nothing was taught. Ridiculous!! It would be best to believe the reviews you see; such a bad teacher is unimaginable. DO NOT TAKE IT, PLEASE!!!

In his view, you should try to figure out the problems on your own, and he acts judgmental as if you asked for his answers without doing anything when you just needed him to help you check if you got it right. Also, real tests will be more complicated than the samples and homework. I promise you it will be a painful class for you. DON'T TAKE IT!!

Fire him please

STAY 5 miles away from this pathetic teacher. His goal is to give tough problems in the exam and make false promises of curve grading. Don't believe his promises. You will be surprised with the final grade. Most in his class get a "C" -- I had all 'A's until I took this course.

Throughout my math career people have told me that most professors don't want you to fail. Dr. Shi is not like most professors. Dr. Shi wants to watch you fail. He is a mean mean man and aspires to rid the world of people that are confident in their math skills. He should not be allowed to teach. Bad person, worse professor.

"Dr. Shi is a great teacher. I am not sure what the people below me are complaining about. IF you actually make the class a top priority in your life like I did, you will be happy with the grade that you receive at the end." -Dr. Shi (he wrote this like an idiot)

Why do I get the feeling that he wants his students to fail? If I was the principal of De Anza I would have him fired immediately. His test does not resemble the lectures or the homework at all.

This is a self study class for me I did not find his lectures/videos to be useful one bit. Every bad quality a professor could have is present in Kejian Shi. He doesnt care for his students like a professor and quite frankly a person should.

I had his asynchronous online course, and I found his resources to be heavily insufficient. He didn't require homework or answers to that optional homework (which was very much not worth the 2+ hours if it weren't graded). The practice tests have no answer key, so it is impossible to be ready for the test. The tests are 100% of the grade.

Practice exams are somewhat similar to the actual exam, except the only similar thing is question 1 comes from section 14.1 in both exams, so it's actually not similar at all, & is useless sometimes. So many points in exams, but few questions so each question is worth a lot. Recorded lectures are useless & boring. If you cant self study dont take.

You're probably reading these reviews and thinking, I can manage I'm pretty good at self-studying so I'll be the exception. That's exactly what I thought reading these reviews before I took this class. I took him for Math 1D and 22 and you need to grind to even get a C. Tests and quizzes are similar to the practice but 5x harder. Stay away.

Worst professor I've ever had. He mumbles a lot, lectures aren't helpful at all so you have to study on your own. He gives a ton of homework, not much point to it since you barely learn anything in his class. However, the worst part is the quizzes and exams, the questions there aren't anything like the HW, and class avg is usually 50-60%.

1: Lots of homework (he gave us 9 modules every week, and said he expected us to spend 2 hours per modules) 2: He will not give out answers to the practice worksheets he gives you, and when you ask him for it, he tells you to 'do the homework' on the textbook instead. 3: Harsh grader, he has to curve the class to 70% avg. 4: Textbook costs $$

Kejian Shi has not put any extra effort into his course in three years. He is reusing the same three-year-old lecture videos that are posted on youtube, and he does not provide students help by email aside from sample tests, of which you will not be provided the solutions. Beware: this is a self-study class only. I wouldn't call this man a teacher.

DONT TAKE THIS TEACHER! Never responsive outside of class, never helpful, don't know why he is still allowed to teach.

Terrible, terrible, terrible professor. I took him because I had to due to scheduling mishaps, and my god i have never been more depressed in my life. Doesnt matter how smart you are or how hard you work, this guy has it out for students and makes his exams unbelievably difficult. It's simple math: Kejian + math = destroyed GPA and will to live

DO NOT TAKE HIM. He didn't give any EC. Your grades rely on your quizzes, exams, and final, so if they are low, good luck. Our highest score is C so he had to curve but we did not know how much he would curve until the end of the quarter so if you see your grades below C, RUN don't wait until he announces your final grade, you will regret it.

Horrible Teacher, his lectures are outdated. He'll usually gives out IDGAF energy and will screw you over. Please Fire this teacher, I had all my classes with Straight A's except this. His average for THE WHOLE CLASS is 40/100!. So if you can avoid HIM. I just did not have any other choice since this is the last class i have to take to get out.

Just don't take this professor. Very fast-paced due to 5 week course but he didn't help at all. He explains concepts very poorly and is just a horrible communicator. Bad teachers in general AVOID him. I took the Class this fall at my University and got an A so a lot of these reviews are valid in what they're saying.

Dr. Shi has a very thick accent and struggles to explain concepts in English. I have to spend so much time after class and communicate with him in Mandarin. Even so, sometimes I couldn't understand what he is saying, I have to ask him to repeat AGAIN, AGAIN and AGAIN. Because his Mandarin dialect accent is quite strong!!!

Fire Him!!!

Please don't take. Lectures reads off the book and wasn't intuitive for me to understand. Doesn't go over homework problems. Has 1hr of office hour on Tuesday. I asked for more office hours and he said to ask during class. If you take, just know that the tutoring center and your textbook is your best friend now. At least for a few hours every day.

VERY difficult exams and quizzes. these are the only things that make up your grade. awful class.

This professor goes out of his way to make quizzes and tests harder for you. He has a really heavy accent that's really hard to understand and what's worse is that he doesn't record the class lectures till the 6th week of class, and the only thing you're graded on are the quizzes and exams. Just RUN.

Dr. Shi is a mathematical genius. He can teach all math classes. You can always find him in the course that other professors don't want to teach. I hope De Anza could arrange more professors to the advanced classes instead of relying on an old guy who is about to retire.

Why does De Anza allow this guy to teach so many of their classes? I have never taken a more unnecessarily stressful college class before. Constant major mistakes in emails (time/place of exams) and constant mistakes during lecture problems. Doesn't round until the end of the quarter.

You will never find a more detestable teacher than Kejian Shi. I never knew someone in academia could be so lazy and spiteful. Exam times very harsh considering difficulty. In review sessions he couldnt even match the exam pace he set. Doesnt care about students. Awful at explaining things. Utter lack of compassion. Likes to watch students fail.

The professor has a very heavy accent cannot understand anything . If you ask question's and he doesn't know then just nervously laughs it out . No extra credits . The assignment load is very heavy . Don't take his class

4hrs of study 7 day a week minimum. Hard tests with class avg 60%. Useless lectures & office hours. 4.0 student breaker. Jeopardized multiple students UC admissions. Pointlessly stressful. All negative reviews are true! If you think you can handle it you are wrong! You will hate this professor! DO NOT TAKE!

i got docked a point on a 33-point quiz for spelling "complement" as "compliment". i consider myself pretty good at math, but got a D on the final. he grades hw based on completion and drops lowest hw score. his video lectures aren't that good but you can look at them to see solutions to similar questions on the test. doesn't communicate well.

There are good professors, capable of simplifying even the hardest topics down to clear, understandable pieces. There are also terrible professors, somehow capable of making simple topics hard, and moderate classes impossible to pass. Kejian is the latter. Despite refusing to teach, he puts the hardest questions on tests. Never take his class.

You might wonder why I selected the hilarious tag to describe this professor. It's because he expects his students to master the material, and ace his tests, despite refusing to even teach properly. Uses videos from the pandemic and when asked to demonstrate an example, sent me steps like an ikea instruction manual instead of actually solving! RUN!

No... Dr. Shi & Professor Bourgoub are the worst math instructors I have ever had.

I consider myself a great student and I never write reviews but everything these comments are saying are so true. He gives MASSIVE amounts of homework each week and spends more time trying to figure out his computer and iPad than actually teaching the subject. This class alone should make be considered a full time.

This guy cannot care enough to even respond to emails. His lectures are terrible, he takes longer figuring out how to actually work his computer than to teach. He stutters a lot in his lectures. If you have questions he does not care enough to respond.

With 6 total homework assignments with averages of about 55+ questions, 3 quizzes, 2 midterms with an hour limit, and his final his class load is way denser than your average class and makes it difficult not only to learn but progress as it feels it's set up for you to fail rather than pass the course.

Not really sure how else to say it, strong accent, doesn't respond to emails, petty teacher, don't take unless you really need to

This is the worst professor. I would request for a grade and he would refuse to put it on canvas and would just say that it was on his score sheet. Homework on is 20-25 pages each and he grades it based off of accuracy but would never give an answer key for the HW or the study guides to ensure what we were studying/practicing was correct or not.

What hasn't been said about this man? 75+ HW questions a week. He uses the same lecture from covid and just answers questions during class. Its 2 weeks after the final and still not 1 thing has been put into the grade book. Hes hard to understand and on top of it all. Class avg for the midterms were 50% and 60%. DO NOT TAKE HIM. Wait 3 months.

Class avg on midterms 1 and 2 were 50% and 60%. 2 weeks after class ended we still haven't received a single test grade. If you like learning from a teacher he's not for you because instead of teaching he just links his old lectures from 2021. Unless you already know calc C and are taking this class for fun, DO. NOT. TAKE. HIM. save your grade

Class is 100% self study he does not teach. Gives horrible practice tests where the real tests have no similar questions.

nobody has any idea what he's talking about half the time, doesn't make sense, assigns a lot of homework due in a short period of time

No extra credit. Please do HW and attend class. It's count toward your grade. Hard grader. He knows if you cheat in the quiz or test. Don't take his class unless you have no other choice

If you choose with him you can't get an A. With all the heavy homework and quizzes he will always fussy, and you can't get a high score. I'm not sure how that helps a student? I think he needs a new way of dealing with students.

The amount of homework this class has is ridiculous, the lectures don't help you one bit either, and the tests are also extremely hard, don't take him, getting an A is near impossible.

Do not take this class Anurag

Dont take this guy. Insane amount of work every week, along with tests that are basically there for the whole class to drop out slowly. Very hard class.

Kejian Shi should not be teaching. He has few redeeming qualities, if any. He assigns homework consisting of 65-130 problems to be completed every 2 weeks (consecutive weeks before the final). Cuts points for spelling mistakes on tests. He grades homework based on completion apart from random scrutiny. Don't take his class if possible. He lazy.

DO NOT TAKE THIS PROFESSOR!!! EVEN IF IT IS ONLINE!!!! Lectures are not helpful, tests are extremely hard (exams avg around 40-50) Take points of for random mistakes (even for spelling???) As a reference, I am a straight A student for my entire life This is the first class, despite 40 hrs per week spent on this class, I only gotten an A- in.

Get ready to do a lot of homework, usually around 15 to 25 questions a day. It's hard to keep up if you have a job.

I was about to take the quiz, but couldn't be bothered after reading the reviews on here. "Very Easy" rating because I did not even bother with his class 😹 #freeweekend #nohomework #easyW

Why he is still teaching? This guy shouldn't teach anymore.

it's almost impossible to get an A in his discrete math class. He randomly takes points off and doesn't tell you what you got wrong. Lots of hw. i've been getting straight As and i couldn't get an A in his class even though discrete math itself is not hard.

Worst professor I have ever had, final is worth 200 points while each midterm is worth 100. Tough grader, no feedback. Class average before the final was a 71% and im sure its was much less after the final as i completely failed it, that tanked my grade to a 61% Avoid this prof at all costs

Litteraly the most inconsistnent grader I have met. My husband and I took this class together and all of our assignment were 15-20 points away from eachother.

Diabolical accent, teaches nothing in class and rather expects us to learn it on our own and ask questinon sin class ,extremely tough grader , literally no one in my class liked him.

Don't take him for your own sanity. He gives very little feedback on quizzes and tests and is very very tough as he doesn't give sufficient time in order to take the tests/quizzes and at most he'll give you an hour until you have to submit the test but then you need to convert it to a pdf then submit it which takes a couple minutes off of your time
