shoot your head before taking this course. tests are rediculously hard and his lectures don't help.

He stands in front of the board mumbling gibberish and writing furiously. Ask a question, and he re-writes what's on the board, glares at you and says, "See? It's easy!" He teaches way above everyone's head. Tests are impossible.

Oh my God this guy is the worst professor. He can't teach his exams are impossible, and overall He so far the WORST professor. NEVER take this guy

Terrible teacher. Bottom line nothing else to be said other than OMG he's so dreamy!

Makes relatively easy subject matter nearly impossible on quizzes and tests. Somehow got an A but would strongly recommend another professor, there's hundreds for 142, lol.

Horrible.

No Comments

TERRIBLE! He is unorganized, confused and is intentionally difficult. He will teach the material in very basic form and on the test add twists to the problems that make them 10X harder. His syllabus was given in the 3RD WEEK OF CLASS! No useful information on it at all. stay away if you care for your gpa.

He says he wants to help then literally says 'don't bother me', when you ask a question. Miserable man.

Very hard exams. Horrible teaching skills.

He seemed totally uninterested in the class. The syllabus was given out three weeks into class, and then too it consisted of one single page telling the students of the professor's email id and contact info. Very very bad TA, bad teaching, hard tests, sometimes takes attendance, sometimes doesnt. A clumsy, stupid teacher. Dont EVER take him.

grad student's don't even understand his test

Absolutely the worst prof ive ever had, many times confuses himself with his own examples, not clear, rambles alot. No slyabus until 4 weeks in. Gives ALOT of homework. if you ever get him for 121, i suggest just reading the text book it helps alot. I've taken 141 and this class confused me.

Worst professor ever, too bad he's tenured because if he wasn't he probably wouldn't have a job. Don't take this class with him! The only easy thing is to realize that this guy is a terrible professor! He expects you to know the material as well as he does!... COMPLETE CRAP!

Makes lots of mistakes, useless to ask him for help. Rescitation a must!

so so horrible. i just gave up on this class after 2 tests. i feel sorry for the people that are stuck with him.

Calculus 1, Math 141 is already a difficult course. He made it more difficult with insane tests and quizzes. You know it is going to be a tough class when he says that 50-70% is good. He is unclear and his examples are terrible, the book is better. I learned more in the help center than from him. His tests are worthless.

Yells at you when you ask him a question, tries to sway you from coming to see him during his by appointment office hours. He just stands at the chalkboard for 50 minutes and shows off his equation derivation skills to the class. He puts topics on exams that he tells us will not be on them. I would not recommend this professor to my worst enemy.

One of the worst professors out there. I rather shoot myself than take a class with him. This guy needs a mental evaluation. He assigns over 60 problems a week which will take you most of your weekend to finish, and calls it easy work. Exams are extremely difficult and blames the low test grades on your studying skills. His lectures do not help.

There is no way to prepare for his exams. It's either you know the material previously from another time you learned calc 3 or you fail. Everyone in class is lost as usual and he is very disorganized while giving lectures. This man needs to retire NOW! He is destroying peoples lives with his horrible skill called teaching.

I do not know where to start with this guy. He teaches like everyone has seen the material before and should know what hes talking about. Tons of Hw that isnt even graded. He just gives a check. There is no organization. Don't take him!!!!

WORST PROFESSOR EVER!!! he doesnt talk to you, he talks to the board. you feel too intimidated to ask questions becuase he barks at you and says its easy. i could probaly learn more from anyone else in the univese. he is very mean. is you care about your GPA stay away

Intimidating teacher who is too smart to be teaching this class. Assumes everything is easy and doesn't answer questions or doesn't answer them completely. I HATED HIS CLASS with a passion. (i'm a math major)

He's the worst teacher at UB. Doesn't explain anything and makes you feel bad for asking questions. His tests are ridiculously hard. Thanks for ruining my life ;)

The WORST!!!! I cant believe that they let him near a class room. He is no help and even told me to "talk to him when he is getting paid for it".. He is rude and very unprofessional. If you plan on understanding this class you will probably end up reading the text and "pauls online calc notes" good luck your going to need it.

Worst Professor at UB, teaches like all his students are mathematicians, runs out of class so you can't ask questions and when you do find him he pretty much refuses to help you. Doesn't respond to emails and doesn't have open office hours. You'll but so much time into his class and still fail when you could get an A with any other prof. DON'T TAKE

This was the hardest class I have ever taken all thanks to this teacher. He goes through problems says "every one get it? good lets move on." No one ever gets it. His tests and quizzes are redic hard. The class average for quizzes was 20, 40 then exams was a 63. His quizzes take just as long as the tests do too. STAY AWAY if you like your GPA

I TOOK AP CALC IN HS AND I STILL MANAGED TO RECEIVE AN F IN THIS CLASS. THIS PROFESSOR IS EXTREMELY INCOMPETENT B/C HE DOESN'T TRY TO HELP STUDENTS. FROM BEGINNING TO END OF CLASS HE'S TALKING TO THE BLACKBOARD. HIS CHICKEN SCRIBBLE ON THE BOARD IS INCOHERENT. HE'S PROBABLY UB'S WORST PROF, THUS A LIABILITY MORE THAN ASSET. BE SMART AND AVOID HIM!!

Sageev seemed like a nice guy in the beginning, but he would just assign a ton of homework and rush through the lectures. I dropped the class after seeing him belittle anyone for asking questions, like THEY were stupid for asking. Side-note: he wore the same sweater-vest every day. Brown.

The mandatory workload is minimal, but you need to do it to keep up with the material. His lectures aren't very useful, so get to used to reading the book. Also, the grading policy isn't very clear and you will have no idea what to expect as a grade until you get it at the end of the semester.

I was in his class for two days before I dropped. And I am glad I did. He never faces his students when lecturing. He writes and faces the board the entire time. And he asks if you "got it" and then moves on before people can say no. I love calculus and I took it last year. I was excited for this class but he made me hate it. Find a different prof.

this guy has tenure so he's not going anywhere. He doesn't help doesn't post office hours and messes up the formulas and equations he is supposed to be teaching. If you have him as a teacher, switch to a different teacher right away, the guy is way past his prime.

Does not teach at all and if you attempt to ask a question he replies with some ridiculous statement such as, "you don't know the law of cosines? why are you alive?" or "even fish know calculus" the tests are very difficult and aren't similar to the homework assigned. He is unapproachable and seems complacent with teaching in general.

Horrible teacher. Tests are impossible and do not reflect what was reviewed in class. Very demeaning to you if you dare ask a question. Cannot believe I had to pay for this class.

Very tedious man. Talks to the board and tries to explain his work by saying "this thing and that thing, do this to get that" Not helpful. Doesn't understand students' questions. Tests are the only grades, and are mostly conceptual problems rather than like homework problems. Homework takes hours and doesn't help grades. Always Keeps class late.

His teaching methods are awful. Just read the book, and do the homework (the meaningful parts of it, a.k.a. the problems that don't require proofs). I learned virtually nothing from him. I self-taught the whole course and somehow got an A. The class average for the final exam was in the 30s, wow.

Terrible teacher.Has the hardest tests in the entire math department.Teaches beyond the course material. Bonus questions count against if answered wrong. Isn't good at answering questions at all

Very difficult to follow his lectures. He makes several mistakes in class, so if students don't correct him, you may be left really confused. You will be teaching yourself most of the time. Exams are tough, even with prior knowledge in the topic. I recommend avoiding this professor if possible.

No syllabus. Exams are handwritten and hard to follow. Does not explain his grading policy. If you ask a question during class, it will not be answered. Homework ... not sure it was even put into the grades...

YOU WILL FAIL!!! he is veryyy smart but he doesnt know how to slow it down for students. All of my engineering friends failed his class as well as me. Do not take him. There is no structure and his test are impossible. I would not even know how to start one of his test problems. When I retook the class I got an A.

In hindsight he sucks! I have a good job in mechanical engineering and his demands are not reasonable. He's not brilliant. He's a man who has taught the same nonsense for decades. We'd all be brilliant belittling freshmen regarding the law of cosines after 30-years of practice.

quite abrasive, but funny

Dr. Sageev makes you know your stuff, and study hard (he gives at least 40 problems including proofs/week of homework). In order to do well in his course, it appears that you would need to spend well over the recommended number of hours on it. If linear algebra is your thing, then I'd say take it with Dr. Sageev & work hard. Otherwise, steer clear!

Doesn't have office hours. Will not respond to emails. Over tests - tests are completely insane. Avoid at all costs. This class has been a complete nightmare

Possibly the worst professor at UB. Department chairs tell people to avoid him at all costs. His class consists solely of derivations. He refuses to hold office hours and runs out immediately after class so you can't ask him a question. Does not teach how to apply equations. Tests consist solely of proofs. Mumbles into board. Avoid him.

Awful awful teacher. Perhaps the worst ever. DO NOT take this class. Hard to follow, a lot of Hw, and his home made tests are impossible. Did awful in his calc 3. I would normally never write a review of someone but he is so bad that I took the time to do this

This prof. is useless. I knew the material already but still found hard to keep up with him. He takes more midterms than anyone and gives a lot of homewor. Dont take this class even if you dont get any other instructor.

Useless professor. He will unteach things and leave you blank with maths

Please DO NOT TAKE THIS COURSE. He is a horrible teacher and person. He teaches to the blackboard, ridicules students who participate, refuses to answer questions or repeat himself, tests are impossible expect 20s-40s averages, and he gives ludicrous amounts of homework, most likely to provide himself with an excuse as to why everyone's failing

Worst at UB. 1) Go to every class. He says attendance isn't mandatory but starts having you sign in a couple weeks in. 2) Do all homework and hand it in to recitation 3) Do not give up. My tests were 38, 26, and 59 and I'm pretty sure I bombed the final but I got a C-. Not the best grade but all year I just was terrified I was going to fail.

There are so many homework. The exams are too hard to get a decent grade. Average score of quiz or exams are around 30-50. He will not answer your "silly" question because you should know them before taking this class!!! Got nightmire because of this class. Never take his class!

Absolutely the worst professor I've had. Unprofessional and very quick to blow off your concerns. Tests are poorly constructed and often unsolvable. Good luck trying to get extra help. He doesn't have office hours and is VERY difficult to meet with. You've been warned.

By far worst professor I've encountered at this school. He doesn't answer questions straight forward and if you need clarification he will very quick to put you down. He is very straight forward and will tell you if you will fail his class. IMPORTANT: Engineering professors make a note of warning other students to avoid this professor at all costs

This Professor was absolutely terrible. It was very difficult to determine what chapter he was on. Spends the whole class jotting down random proofs on the board. Don't expect to get anything higher than a 50 on a test. There was tons of homework and none of it was relevant to what was on the exam.

Don't do this to yourself. Learn from the people here and avoid at all costs.

Please, just please not this.... If you have no option other than his class, consider taking your MTH class in the next semester. Probably God suggesting you, son take a break from Math this semester or else Gershon will happen to you.

His lectures are completely incoherent. He stands there and does proof after proof without explaining any of the methods for solving the problems. He'll ask "is everyone getting this? Hello?!" at least three times per class, but provide almost no guidance if you don't get it. His tests are basically proofs that the book doesn't cover how to do.

Test is not solvable. God suggesting that just avoid... because God can't solve it either

God awful. Smart man, terrible professor. Exam questions are HAND-WRITTEN! More power to you trying to decipher his handwriting. Not to mention his nasty remarks. Avoid at all costs!

Worst professor ever, i can't imagine why Ub ask him to teach Mathematics. When he give us homework he try to change some number so that question will be unique and can't find solution online. His changes just destroyed the whole question and make it unsolvable at all! I thought he never think for the question he try to give to us.

Has a huge ego, not easy to follow

Impossible to follow in lecture. Get ready to teach yourself the class

The fact that Dr. Sageev is still teaching at UB is a sign of the terrible tenure system. Professors like him are allowed to get away with anything. He is by far the worst professor. I am an honors student who has excelled in college only to drop his class. He is arrogant and treats the students like dirt. You won't learn anything in class.

go and find some courses video useless lecture and horrible professor

He does not care about you nor your grade whatsoever. Avoid him at all costs. If your life sucks that bad and you end up with him, I suggest finding youtube vids. He blows. You have a better chance of winning the lottery than actually finding him in his office during HIS OWN OFFICE HOURS. Joke of a professor.

Professor is terrible, lectures make no sense, all full of proofs, and his tests are hard, only good thing is he curves his tests like crazy.

Worst professor I've ever had in my life and I really mean it. Throughout my life I've been getting A's in math classes, but when I took his, I think I'm getting C. If you have a question about something don't ask him, he won't help you. Also, don't send him an email, he won't reply. the book is full of equations, he doesn't allow formula sheets.

Worst professor I have ever had. Do not take him under any circumstances, even if he is the only one available. He assigns tons of hw that doesn't count towards your grade! 50% for a final and 50% for three exams make up the grade. I wish he would just get fired, he is that bad and can't teach. Destruction be upon him and the very day he was born.

He likes kids who go to class. He is very very smart so it's hard for him to understand that people are struggling. If you want to do well make sure you know the chapters covered for each test and then go and DO EVERY SINGLE PROBLEM FROM TEXT, EVEN PROOFS. Tests are questions STRAIGHT from the books. Just do better than the kid sitting next to you

Just don't take him lol

DO NOT TAKE THIS PROFESSOR!! He is a terrible professor. He stands in front of the board writing tons of stuff, with minimal explanation. Homework and attendance are not mandatory, but he claims, if you show up and turn in the homework, that he will curve your grade. Grade is based on 3 midterms and a final.

Sageev is by far the worst professor or teacher that I have ever had in my educational career. The course was ridiculously stressful on its own with a teacher who dismissed students who dont understand the material just by looking at it. Why hes even allowed to teach still is beyond me and UB is making a huge mistake keeping him around.

This man is a terrible professor. I passed his class and had some of the highest grades in the class but he is just awful at teaching and helping students understand his class, just use paul's online math notes to teach you and you'll have a good chance to pass

Sageev is the worst professor I have had here at UB. Drop if you have him. He is incredibly difficult. Lectures arw confusing and tests and quizzes are insanely difficult. A lot of self teaching done for this class.

If you have the chance do not take class with this professor. He like many professors take the "teach yourself" method where he expects you to teach yourself. He confuses himself during lectures, makes mistakes then 10 steps later expects us just to know where he went wrong. Does not teach, the averages for his tests stay in the 40s.

Does not hand out syllabus. He just tells you his policy on the first day. Lectures are disjointed; his explanation doesn't match the textbook. Even he don't know what he did wrong when explaining things. Gives out too much hw but doesn't grade them. Grade is determined by 2 quizzes, 2 midterms, and a final. DO NOT TAKE HIM UNDER ANY CIRCUMSTANCES.

Sageev is the worst professor you can have at UB. The way he explains topics is old since hes been doing it for 40 years. Which is why his lectures are too confusing. If you do not rely on outside help (YouTube, tutoring, etc), then you are guaranteed to fail his class. This happened to me and I was dropped from mechanical engineering.

Dr Sageev is a horrible professor. First of all he walks into class wearing sunglasses. This is a clear sign that he doesnt know what hes doing. He expect all students to rearrange the chairs before he walks in. If you sit down and do nothing, hell scold you, and possibly even lower your grade just for getting on his bad side. Drop the class asap

Whatever you do, don't take him! He talks to the board and states after every sentence, " Did i make myself clear". Also, he states that what you do for homework is gonna be on your test not classwork! Every class he gives out a lot of homework. If you're gifted in Math you may survive but if you're not you won't. Listen to the reviews its all true

I was only in this this class for three days and I had no other choice but to drop out. He is rude and just simply does not teach. He makes you turn your desk so that he can use the chalkboard and no syllabus and has absolutely no lesson plan. I had no idea where he was going or even what he was trying to teach me. I was left with no choice

Hes literally so confusing. Do not take any of his classes. He doesnt explain anything well at all.

Doesnt know what he does in class. WORST PROFESSOR EVER!!! Doesnt explain things!

If you see that you have Gershon Sageev as your professor, immediately drop the class. Don't even take a chance with it. His lectures made zero sense, and I had to learn EVERYTHING outside of class on the internet and in my textbook. His lectures were pointless. I dropped the class and am taking it in the winter session instead. DROP HIS CLASS!!!

Do not take this class. He is the worst professor Ive ever had!

Taking this class is the single biggest mistake I've made in my 20 years on Earth and the single biggest regret. Has a huge attitude, treats students with disrespect, confusing and does not care for your success at all. On the verge of failing out of engineering and Calc 2 is the cause? "Get a tutor", he blatantly said before walking away from me.

Just see for yourself.

If you get stuck with him and cant switch to another professor, just wait until next semester to take it. He makes up questions on the spot that make such little sense that he cant even finish them. Dont except to learn anything in class. If you want to pass youll have to teach yourself outside of lecture.

ive really enjoyed my time at UB and have had some truly excellent professors. professor Sageev is an unfortunate exception to the norm of good professors at this school. He is entirely uninterested in helping; he offers no notes, and when asked for clarification he will snap back with a read the textbook if youre unsure. Terrible guy.

Awful professor! So mean and doesnt like to answer questions. Would write on the board, say nothing about it, and continue to write. Very confusing, had to drop the class because I could not learn from him. do not take classes with him!

Probably the worst calc teacher on campus

Gerson Sageev was hands down the WORST professor I have ever encountered. Not only was he extremely rude, he barely knows what he's talking about. He gave around 70 problems a week that counted for a super small % of our grade. He faces the board the entire class. Thank god for recitation because without it I would not have passed at all. DON'T.

don't take him, i did great in high school in all math classes then i took calc and got so completely lost. none of his lectures make sense. If you can try not to take his class, however, if you have too, show up to class as attendance matters, i think thats the only reason that i am passing the class but havent gotten my grade back, read textbook

Unfortunately I have to take this class and only about a month into school I have zero confidence I will pass. His lectures are basically spoken in gibberish, he faces the board the whole time, his biggest problem is he thinks we all already know what hes talking about from previous math courses weve taken. DONT TAKE THIS IF YOU DONT NEED TO!

Sageevs lectures are nonsense, with students having to correct him on almost every problem. Constantly blocks what hes writing on the board with his body, making it extremely hard to keep up. When he gets too lost, he will go silent for minutes at a time trying to find where he got lost. Frequently starts class early. 0/5 if I could.

Literally the worst professor here. Barely understandable. Get lost so easy and then makes so many mistakes in his lecture. SWITCH OUT ASAP. Thinks we know the material, which we dont. Turns around any questions and turn right back around. Literally the worst.

His lectures are very incomprehensible. Very difficult to follow in class and doesn't do a good job of making sure that everybody understands his lessons.

This man speaks at the board for the entire class. He gets frustrated when we don't understand stuff that he is briefly going over. Recitation for this class is the only reason I passed. He gives hundreds of hw problems every week (no exaggeration) and doesn't let you fully ask a question without him interrupting. DO NOT TAKE IF YOU CAN

Awful guy. He literally hates his students. Dont ask questions, he will accuse you of insulting his intelligence. If you sneeze or sip your water bottle he will pause class. Speaks absolute nonsense.

I took this class 4 years ago, and I am still scarred by the experience I had with this professor. Before this class, I LOVED calculus. This class changed that for me. He would just put long proofs on the board and say "this is a fact" and move on, talking to the board. He was incredibly difficult to talk to, and I only passed thanks to youtube.

Don't take Calc 1 with this moron if you value and GPA and scholarship.

Sageev is too overqualified to teach UB students. He is better for teaching Math in colleges like Boston University, or MIT. He previously taught a class at MIT. If you are a math major or have high aptitude before, get Sageev. If you a non-major and just want to pass, taking a class with Sageev will ruin your semester.

So I got an A in his course, and the ONLY reason is because I took AP calc 4 years ago. He refused to explain concepts that he felt were "trivial" but then would yell at the class for not asking Qs. It's not impossible to do well if you know calc already or are ok completely self teaching, but if you're new to calc do NOT take it with this prof.

Taking this class during covid 19 pandemic. His setup is a camera pointed at the whiteboard. It is constantly unfocused and he stands in front of his writing making it very hard to take notes. I contacted the head of the math department to help set him up with a digital whiteboard and was told he had one and didn't want to use it.

He is an absolutely terrible professor. I had taken every all of the calcs, diff eq, linear algebra, and gotten an A in all of them with the bare minimum effort. This teacher is so terrible at explaining things. His lectures don't match the homework and he assigns way too much homework. Do not take a class with him if you can avoid it.

You have to teach yourself in order to pass this class. He communicates terribly and even his TAs have no idea what is going on. He only does two examples of questions during lectures that dont even make sense with whats going on. You need the book in order to teach yourself if you want to pass.

I only took this class for 2 days and I dropped it and switched professors so fast. He was super unprofessional. He was late to our first class and didn't even give us a syllabus. He didn't set up UBLearns because he said he was "too lazy". He has super sloppy handwriting. He doesn't answer peoples questions. DONT TAKE THIS CLASS.

Showed up late on day 1 of lecture with no mask, syllabus, and UBLearns. Doesn't make or isn't allowed to make his own assignments and tests, so it's all from another professor. He said homework was online, but he didnt give a website nor uses technology. Dropped his class the second I walked out.

Took the class many years ago but just had to come back to warn others because that's just how bad he is. Basically just writes proofs on the board and you have to teach yourself. Was told by him a 46/100 I got on a test was well above average, that's insane. Once yelled at a deaf girl to take out hearing aids he thought were headphones. AVOID HIM

Does not even know where he is or what he is doing. He would forget when class ended, write equations down wrong, and get confused when students would correct him. Went to office hours once and he told me to go home. No UB learns, syllabus given in the third week had the wrong dates, forgot to grade my exam (twice), and can't answer emails.

He considers his job to be to weed you out, NOT teach. He also clearly is one of those who give top priority to research, NOT teaching. Back when I went to SUNY Buffalo, he did't even hold office hours, even though they were supposedly "required." That may have been some time ago, but going through the other reviews, looks like nothing's changed.

No office hours. Really rude guy too. Can't teach to save his life.
