Frankly, this professor doesn't teach, instead he just read straightforward PDF files that are slightly modified book pages. The book is really terrible because it has many to misprints. After solving problems, you will get mad because your results do not match the answers on the back. Tests are multiple choice questions without partial credit.

This is the worst math class I have ever taken. His tests are so UNFAIR. Would reccomened every other 427J professor over him. Truely an unbearable class. He tests you over things he doesn't directly go over, was flabbergasted when I saw the questions on the midterm.

10/10 would not recommend his class

Pretty sure he wants you to fail. It's his way or the highway. By far has the hardest exams out of every professor, extremely unfair.

WOWZA his exams are incredibly, outrageously hard!!! Take any other professor for 427J and it should be no problem. There ARE good math professors but he is not one of them. Had to learn everything from the TA.

Worst professor ever! The only thing he taught you well was how you're going to fail his class. Hard tests, never really teaches us. He taught us from pdf which is not helpful at all. Avoid him at all cost. He always laughs at his own joke and it's not funny at all.

Exams are extremely hard (mostly proof based), final is cumulative and he won't even give a hint of what could show up (that means memorizing 150+ proofs from lectures and homeworks to even consider passing). Only good thing is attendance boosts grades, it helps those on the verge of failing. VERY HEAVY PROOFS. Don't take if there's other options.

Easily the worst professor I've had. He's so full of himself, and won't take any criticism. No curve because his tests are "totally fair" which isn't true at all. He works easy examples in class, so you're pretty much on your own for the rest.

The grading is bad, bad teacher and could care less if his students actually learn

Pros: -Posts notes online -Homework load is manageable -Willing to answer any question Cons: -Proof explanations lacked clarity and are difficult to follow -If you are completely lost asking questions didn't help and will confuse you more -The exams are extremely difficult and vary every year If you struggle with proofs skip this professor

Multiple choice exams, if you miss 3 then that's a 70, on top of that if your work is missing something, you get points deducted. Never works through problems, only refers to his "wonderful" website he made years ago. His lectures are quite pointless since you can find everything he will be teaching from the website he aimlessly points at

this was the worst class I have ever taken. lectures are confusing & asking questions rarely clarifies things. says "there's no such thing as good teaching" & refers you back to his website. 66% of students failed our first exam & he said "you deserve it" (& seemed rather happy about it) instead of acknowledging that maybe he wasn't teaching well.

Kiryl simply does not know how to teach a class. Everything "taught" is on his awful website that is impossible to learn from. Quizzes are not bad because they come from book problems but, the tests are questions based on tiny detail seen in one line of his notes. Avoid Kiryl at all costs as he will hurt your GPA. Worst teacher I've had! Sad!

Never saw him work out a problem. If he weren't so unintentionally hilarious, I would have dreaded his class a lot more. The attendance curve will be the only reason you pass. Even if you know everything from the notes it might not be enough to pass the test. "Tiny detail, yeah baby yeah." Very intimidating & make sure to raise your hand for the RR

You have to go to every class to sign in on a sheet of paper in the front. The material is already hard enough to understand and Tsishchanka does not make it any easier. The tests are multiple choice with no partial credit. However, you can get points off if you don't show you work. It makes absolutely no sense! Avoid at all costs!

If you're a math major, Tsishchanka is the professor for you. His lectures are strongly centered around proofs and theories, and he has a complete understanding of his subject. For engineering majors, take another prof at all costs - one that hopefully focuses more on application rather than the machinery behind a problem solving method.

Lectures are him reading his notes to you off his website that you have access to. Partial credit on tests only counts against you. Hard material. Doesn't believe in education but is a professor?? Study for weekly quizzes by looking at past quizzes and hw. Attendance only counting for you is the only beneficial thing he does for students. FastPaced

Arguably one the worst professors I have encountered in my educational career, as some of the other reviewers have mentioned, he will be open with you that he doesn't have any faith in education and that he has no intentions to try to fix it. The lectures are a scattered resuscitation of notes that are just copied straight from the textbook.

I have never been in a math class where the professor doesn't work NOT ONE problem during the entire semester. You have to follow through his already typed up notes. The exams are VERY difficult. If you guess correctly on Multiple Choice, he will count points off for incorrect work. The class was unnecessarily difficult. Find another professor!

his teacher is lazy, uncaring, and a bit rude. His class is a bit of a mess. In his class he reads off his pdf in his accent insisting students ask questions, typically they can't because no one knows what is actually going on. His tests are more complex than the material you use to study for it, the class avg on the test is 49, 55 % fail

You can attend the class and still not understand the material just as much as any student who skipped class would. Reading off of a pdf isn't teaching, it's just plain lazy. It isn't the material that's hard, it's the way that it's explained, or should I say isn't explained to be more realistic. Don't waste your time or money on this professor.

Prof. Tsishchanka is very knowledgable about the material, but he is a terrible teacher. He just goes over his notes and doesn't really show us how to solve problems. He periodically comes on this site during lecture and grills his students about giving him negative reviews. I have never had a math class this difficult. Don't take him for M427J.

Lectures consist of him reading a pdf of the textbook, scrolling up and down as he talks, making it very difficult to take notes. The first test was 9 multiple choice questions with 10 options each, all very similar, making it very difficult to determine the correct answer even if you're close. It was curved from a 47 average to a 49. DO NOT TAKE

After studying diligently for first exam, which was 9 mc questions with no partial credit, I received a 60. This was above the 49 class average. This professor is adamant that he "can't teach" his students, rather we are to use his website. The website is a good resource for the course, but the format of the course is impractical for STEM majors

Tsishchanka, it's 2020 my guy. If you really hate education and not care about students, consider quitting.

Was not worried about his class and studied normally, but the first exam absolutely killed me. The class average was 49, with a very small curve. Over time, I began to see his laziness and lack of care for how students do. I've always been very good at math, but this class is out of my league. Very hard for online school, avoid at all costs for GPA

If you want a bad GPA get him! His way of teaching is highlighting prewritten notes while jumping back and forth between concepts so it is hard to keep track what you are learning. Also he has yet to work out a single problem which confuses me because its a math class. The math department knows that he is a problem but refuses to do anything.

Worst class at UT.

Math is not supposed to be taught by reading pdfs through a video stream, students need to see worked examples in order to learn. After the first midterm average was 49 (median 47) over 1/3 of the class dropped, and no changes were made to the teaching style. This professor is a prime example of making students lives harder during this time

Literally the worst class I have taken at UT. Started off odd because he only reads from his PDFs that are basically summary of the textbook. He gives tons of material which is great, but then gave a test that was much different than any material he has out there. Over half the class failing the first exam and 1/3 + dropped before the deadline...

Do not take his class. This professor is the epitome of a teacher who does not care about his students. 49% class average on the first exam and he did not make a single change to his teaching style afterwards. The exams are 9 MC with no partial credit. You can know all the material but make one or two mistakes and your grade plummets.

Throughout the entire semester, this man did not work out a single problem during lecture. His lazy teaching style consists of reading over a pre-written, copy-pasted pdf from the book. Absolutely ridiculous how little he cares about his students. Made the class even harder during the pandemic for no reason. Do not take this class.

Lectures consisted of prof scrolling up and down a pdf of the textbook, making it very difficult. Tests were multiple choice with many similar options, making it extremely difficult to find the correct answers. The first average was a 49 after a slight curve. DO NOT TAKE

his main issue is that lectures need questions to be good. Very rarely is there question influx, cuz there's not enough work to process. Also, mult-choice approach with few questions is detrimental. Though the latter tests are easier, damage has been done. Please assign graded quest hw for predictability, or do part credit free response exams!

Taking this class was a strain on my mental health. The lectures consist of him reading off a pdf that he has. Exams stray from the textbook problems and there is no homework so exams are your only grade with quizzes. His exam rules were harsh and inconsiderate for online learning bottom line do not take this professor if there are others available

Weekly timed proctored quizzes with difficult questions and exams being the only other grade. Seemed like the goal was to make questions pretty challenging when it was on a quiz or test so overall not a class set up for people to get an A.

Clear disrespect for students, 0 accommodations, and is openly rude to students asking questions about material or grades. Very harsh with grading and his teaching is him reading a pdf word for word. Really, really bad.

Horrible grading.

Prof tsichaka is one of the worst professor's that I have had at UT. He is needlessly ruthless and rude. The class average for the first test was a 44 and over 70 percent of the class failed. When I went to ask about the first test all he told me was that he was incredibly generous and that i am a bad student if i continue to do bad. bad lecture

The only thing that got me through this class with an A was the optional GE course that accompanies the course. Professor lectures by reading off of his 10 year old website and is proud of that. Going to class 3 times a week felt like a waste of my time.

Kiryl is rude, narcissistic, and and awful prof. He'll probably show this on the first day of class because he loves his low ratings. His lectures are basically useless so go to discussion instead. As long as you do the homework and understand it, you'll be fine, especially if you took AP Calc BC.

READ THE WEBSITE READ THE WEBSITE. STUDY WELL STUDY WELL. These are the only things you will hear out of this guy and he literally doesnt teach anything. If youre good at learning from a poorly designed website you may be fine but I recommend never taking him.

Worst prof ever had. Difficult exams, TA discussions had *nothing* to do with actual exams. Had 2 midterms, final, and weekly quizzes, so did not have many ways to boost grade if you bomb an exam. Literally said does not expect everyone to pass and that that's the way it should be. Literally the *opposite* of a prof that wants you to succeed.

I've never left a review before, but this honestly deserves it. Be prepared to learn nothing at all in lecture and have to go home and learn everything by yourself. Worst professor I've had at the University. He just read off his website for lecture. Also, test where unessasarly hard, and he don't care at all about his students.
