He is one of the worst professors I have ever had. His lectures are very hard to understand. He doesn't allow his students to meet with the TA and the grading is very harsh. Definitely stay away if you value your GPA.

By far the worst professor I've ever had. Doesn't teach material in class just reads over his notes word for word rather than practicing the material (sloppy handwriting as well so its hard to follow). DO NOT HAVE HIM! But if you are stuck with him, go to every discussion to do problems with TA's and go to tutoring in order to succeed in the class.

Probably the worst professor I've ever had. Terrible lecture and doesn't teach material that will be on tests. Only goes over theory and not actual problems doesn't explain things will. Avoid at all costs !!

By far the worst professor I have ever had. He reads straight from the 'book' (it is just a document online) and does not stop for two hours. He does not let you see the TA and offers no help outside of class. The quizzes are all true or false questions and impossible to answer the way he wants. All problems are theory proofs (very difficult.)

WORST professor I've ever had. For the entire two hours, all he does is read from the textbook (which, by the way, is an online PDF and unhelpful). He also does not allow students to see his TA, which is unheard of. He wants students to ask questions in class, but he gets annoyed when someone asks him something. 1 star is generous.

All lectures are straight from the textbook / pdf and are somehow harder to follow than reading from the textbook yourself. There is no discussion or TA office hours and he is completely unhelpful in answering questions. Doing all homeworks and reading all sections will hardly do anything to prepare you for his ridiculous true/false based quizzes.

Terrible professor. He is condescending when you ask questions, poor at communicating his thoughts, and an inconsistent grader on tests/quizzes.

Had him as a prof for calc for business. Dont take his class. Probably one of the worst professors Ive had. Lectures right from the book and doesnt explain anything. The test are hard and really the only thing that gets graded. The discussion is a waste of time. All around a hard class that was actually useless :/

Sergii is a professor who doesn't explain material well, doesn't teach really anything but reading off a piece of paper. He expects you to know way too much content for a beginner-level math class. His lectures are pointless and to be frank and honest with you his teaching method is pointless. Your better off teaching yourself than to pay attention

I do not recommend taking one of Sergiis classes if you are not a great independent learner. Sergii does not explain course material well, at all. He is generally hard to understand and hard to follow. Hes a very nice guy, but not the best teacher.

Two words: good luck. Sergii is probably the worst math teacher I have ever had. I have read that people have a hard time understanding his accent, but that's not even the problem. His notes are completely incoherent, and the TAs are not what I would call helpful. I got through the class by completely teaching myself, so be ready to study.

Like a lot of people have said, Sergii is truly a great human. However, he is not a great math teacher. I took his Quantitative Reasoning for Business class and would have had a really tough time if I didn't take pre-calc and calc in high school. The quizzes are very hard, and the lectures/discussions didn't mesh very well.

Lectures arent worth going to, just use the homework and youtube to study. Thinks that when whole class is doing well its an issue of being too easy. Thinks everybody should be as knowledgeable as him when people complain about material getting harder. Use yo ur outside resources and you should be alright, i never learned a single thing from him.

He seems like a nice man, but he has no business teaching. He does not know how to connect with his students or operate technology. My advice is to form a great relationship with your TA and SI instructors if you want to do well.

He is a very sweet man but is extremely hard to understand. The lectures are so pointless and the exams are almost impossible. My TA was awesome but you should be prepared to teach yourself the material. The homework does help with the quizzes which are a big part of the grade.

Sergii is a great guy, but it is so hard to learn from him. He is way to smart for us and isn't the best teacher. I had a hard time learning from his lectures. My best advice is go to your discussions and find YouTube videos to watch.

Lectures are pointless, he cant explain how to do anything

Not a bad class if you can navigate Khan Academy and learn on your own. His lectures are pointless because he cannot explain anything without confusing you or making you feel dumb. Weekly quizzes and exams were super easy because they were online. Photomath is a must.

Very hard to understand during lectures. I passed only cuz I taught myself the material. He also doesn't understand some students' questions and has short temper at times. I asked if we could use graphing calculators for the midterm and he snapped saying that we "didn't need them". I was too scared to ask him again if they were allowed or not.

Literally the worst class I think I've ever taken in my life. Sergi has a very thick accent and goes over the same problems in 40 different ways that make it impossible to learn anything from the lecture. Its so bad to the point where 70% of my class didn't even show up. Everyone I knew had to learn the course via youtube videos.

Sergii may be my worst teacher ever. His accent makes it hard to understand and he confuses himself on top of that. Smart man, terrible teacher. My TA also had a thick accent so I've taught myself all semester. Told us we wouldn't need a calculator. We did. Asks for questions. Gets mad when questions are asked. Ridiculous he still has a job here.

Depending on your TA this class is either easy or impossible. Grading isn't bad just make sure you are in a groupchat

He is a very nice guy but he cannot teach. He is smart and knows the material but his thick accent is hard to understand and I felt that in his lectures that I would unlearn any material that I already knew previously because the way he taught it was confusing. To pass this class you need to attend discussion and make groupchats with classmates.

TERRIBLE lectures, cannot understand him over the computer. Thinks his students should understand everything after 1 example where his notes are all over the place and illegible and gets mad when you ask questions. DO NOT TAKE HIS CLASSES

His lectures were so hard to understand. Then he gets frustrated when you ask a question because you don't know what's going on

I learn absolutely nothing in lectures because they are so confusing and hard to follow. Get ready to utilize YouTube and teaching yourself.

Have to learn everything through your self or through your ta. You better hope you get a good ta

The lectures were hard to follow and difficult to listen to. There are 2 midterms worth 20% of your grade and the final worth 30% of your grade. You want to hope you get a good TA otherwise you are screwed. This is probably the worst class I have ever taken.

Awful he doesn't answer questions and doesn't explain he just rambles

i already didn't like math but now i hate it

Online lectures don't match up with the homework or quizzes so it's basically studying three different types of math problems at the same time. Attendance is required for lectures and there are questions on tophat that count for a grade. Quizzes during class are easy as long as you study and most midterms are only 20 multiple choice questions.

Horribly organized class and teachers who barely know how to work their own sites for their class. Horrible class overall

He's Ukrainian and hard to understand, gets frustrated when we don't understand the content and ask questions. if you have taken calc you most likely will understand most of it, midterms are 20 questions each and the final is 25 and make up 65% of your grade so be prepared. Lectures have top hat and it's worth 8% of grade so you have to go to class

This guy needs to update his schedule to be more up to date. -Creates slides that are confusing to review on, and includes definitions that any 18 year old won't be able to understand well. -Midterms are graded unfairly. 20 questions and are weighted 20-25% of your grade. -Difficult to understand, class is pointless. TA's are most 80% of the work.

The Big Serg was a bit wack but we made it though. If you took any precalc or higher in HS you will be absolutely fine. He does get mad when you ask questions a lot of the time. The TA is more clutch during discussion sections. There is a quiz every Thursday about the topic you went over last week.

Sergii is an interesting teacher, but his teaching styles were even more interesting because they were non-existant. If you like learning through watching chicken scratch on an ipad and listening to a heavy european accent this teacher is for you!

The professor is absolutely TERRIBLE, and his lectures have NOTHING to do with the quizzes every week. You need to be prepared to learn on your own or you will fail this class. Unfortunately, this class is a requirement for many people, but if it's not, then DO NOT TAKE THIS CLASS!

The worst part about Sergii is that his lectures and homework never lined up with what was talked about in discussion. This made it feel like you never knew what was going on since you were learning two different things at a time in the class. If you can avoid him, do it.

By far the worst professor I have ever had and one of the worst teachers I've had since kindergarten. It is impossible to understand a single word that comes out of his mouth. Whatever you do, avoid taking any course he teaches at all costs.

This professor is very hard to understand and is not a great teacher. It is basically your own responsibility to to teach yourself, and very rarely is the information given in lecture helpful. The class is also weighted which makes it hard to maintain a good grade.

Yeah no he IS as bad as everyone else says. The beginning of the class was decent, the first quiz was easy and the second decent. But the last one had a 55% average. My final grade got bumped up an entire letter because of how awful everyone did on the final. (it's 25% of your grade!) The class is a mess with terrible TA coordination and lectures.

This guy should not be teaching. Can't understand a word he says and even if i could hes a horrible teacher. It's not too hard for the first unit and a half because it's review, but when it gets to new topics he's the worst proffesor i've ever head. Good luck..

Very difficult to understand in lectures given not just his accent, but also his constant muttering and hesitations. Even if you could understand him, his lecturing method is unhelpful. Instead of teaching the methods and steps to solving equations, he'll just solve them himself and hope you fill in the blanks.

Hes a nice guy, but he shouldnt be teaching. His accent makes it harder to get and the way he does a topic is the long way around it. Makes the class more confusing than it should be, your ta is make or break for this class. Garret is a life saver

Professor difficult to understand with accent. TA also had a hard accent and even then wasn't much help during discussions. I even went to the SI classes for help and the student helper there wasn't a good teacher. Huge curve in this class. My 53% was a C- in the end. Tophat used for attendance.

Firstly you cant understand what hes saying in lecture and its not just because of his accent but also for how monotone he is. Secondly it is hard to follow along on what he is teaching because of how all over the place he is when it comes to the subject we are on. He will do easy problems but then assign the hardest ones on the quizzes

His accent is so thick and I had trouble understanding what he was trying to say the whole semester. Top Hat is used for participation, so I wouldn't skip. I had to teach myself the concepts through watching videos from the textbook, which is the only reason why I have a good grade rn. His way of explaining the concepts is confusing.

Sergii is clearly a great guy, but he just made math harder for me. Lectures are not productive, and it is very hard to follow and learn from them. Discussions have quizzes once a week (3 questions, 15 points). My TA was pretty good, which made the class manageable, but I definitely relied on my discussion days to learn anything.

Nearly impossible to understand what he is saying. Lecture is almost pointless to attend. Pray you have a good discussion TA. Fairly easy class though.

She is very hard to understand. It's hard to keep up with her in class.

Can't understand what he says, he seems like a good guy but have to learn the entire course from TA or Youtube.

Sergii is probably a nice dude, but he is extremely difficult to understand, which makes actually learning more of a chore than it already is. My TA was fine, but very monotone and made discussion a drag. I would prepare to learn everything on your own unless you get a good TA.

Very nice guy, awful professor. Very thick accent but I could understand him just fine, he simply isnt good at giving lectures. Mandatory lectures 3 days a week that do not help with learning at all. TAs arent that helpful. Content was very difficult for me. Plan to learn everything on your own outside of class. Exams are multiple choice.

His teaching style is very confusing. I attended almost every lecture to get tophat points but learned almost nothing from them. Homework is helpful but takes a long time. Weekly quizzes are annoying but good checks for understanding. Lots of people cheating on exams this semester.

Not welcome in agartha. Heavy, heavy accent. Make sure you have a good TA, pretty sure the good ratings on here are fake.

Sergii should not be teaching. He is incredibly hard to understand. Paying attention to his lectures made me want to bang my head into a wall. He will write the problem and then jump to conclusions without attempting to explain what he is doing. He uses the most mediocre examples I have ever seen by a math professor. If you take this, good luck.

I never wore a seatbelt while driving to his course because I had hoped that I would wrap my car around a tree before making it to his class

Sergii is very qualified in what he does, but I didn't have a good experience in this course. His lectures are filled with mumbling, which makes him hard to understand. His exams are heavily weighted and will ruin your grade if you have a bad day. Also, the exams were disproportionately difficult compared to other course material. Do not recommend.
