Straightforward, will tell you what's in his tests which are of reasonable difficulty (not hard, not easy). If you are willing to go up to him and ask for help, he'll do his best. Serious guy, but you really learn the material from him.

Great teacher. He really explains everything very well. He doesn't just copy the example problems from the book when lecturing *gasp* unlike other teachers. If this guy teachers any Math section that you're consdering, take him.

I really liked his class. He is an excellent teacher, very clear. His test and grading are really fair. He is also really nice.

The best. If you come to class and pay attention, you can't fail. Lev makes math easy to learn. He's a serious guy and his tests are a little hard, but he gives a full outline ahead of time. An interesting character, too.

He is one of the best math teachers at ccsf. He wants all of his student to do well. He is very clear and makes math understandable. His test are easy if you study. Hes such a nice guy and willing to help his student succeed.

i took his class in the summer, and even though it was for a short amount of time, he helped me a lot. for goodness sakes, i understood word problems! don't be scared with his appearance though. he's pretty serious, but a really nice guy!

(Int. Algebra) Totally cured my math phobia! He is very stoic - scared most of the class but is very funny once you "get" him. One of the best teachers I've ever had, no joke. Math made sense for the first time in my life. Made an "A" on every test - just do the homework & it all comes together.

He's a really serious but nice teacher.He takes rolls everyday, he won't give you any make-up test. But he tells you exactly what's going to be on the test and if you did you homework, I think you'll past with no questions.

Good teacher. Expects his students to be as smart as him. Has an accent, so his lecture is quite hard to understand. Other than that, he is very nice. Tests and final are easy as we can open books. No need to memorize formulas. No homework collection.

I took his class last semester, he took everything seriesly and he explained everything clearly. I ended up with an A,and I did learn a lot about Math. He gave the questions that would be on the tests. I highly recommand you guy take him.

Although I got an A at his class, that really took me a lot of effort. He's a teacher full of knowledge, but he seems not welcome to ask questions. His lecture is clear and he didn't collect homework, but his tests are hard. If you're trying to get a A, you'd better think about it.

Great teacher, but not warm and fuzzy. If you can stick it out past the drop date it gets easier. He will do all he can to answer questions and give you the info you need for the test, but the tests are hard.

dont miss class and even though he may come out as a strict teacher he really just wants you to learn. i wish he also taught MATH 90.

I took this class a few semester ago and got an A in it. I did not put much efforts because I had already known those "stuff". I would like to share with you guys. If you think calculas is hard but you have to take it, take him is your best choice. You can use what ever kinds of calculators. The best one is the Ti-89. If you know how to use it!!!!!

Calls roll exactly 10 mins after class starts, If your name is called and your not there your marked absence, THERE IS NO COMING LATE! If you have 5 consecutive absences your dropped from the class - 10 overall your dropped. He does not collect HW. There are 7 tests and a final. He drops the lowest score except final. Pretty easy class

THE GOOD THE BAD AND THE UGLY: Cantankerous old coot that works himself into a frothy lather of anger over errors students have commited in the past, or may make in the future regardless of what's going on in the present. Ill natured hold over from the Stalinist error (used to be in the russian army). Expect merciless public humitiation for asking

Good teacher, he has his own style....you can not late for his class, you have to answer his question, you must study and practice and you can get a B grade or higher. You can drop the worst exam you have had and you may have extra credit--> Ask him questions in the class and answer his questions...group study is good to get a higher grade

honestly, he's a pretty good teacher. he knows what he's talking about, but sometimes people ask questions and he misunderstands the question and he gets frustrated. He allows you to use your notes and the book during his tests, so take good notes and you will pass the class no problem. if you dont pass, there is clearly a problem...

He wasn't that bad of a teacher, he has a HUGE accent. At first, I was like WTF, but it one day you walk in and you just understand him. He is very knowledgable. I WOULD take him again for a different math class. I think he grades a bit tough though, but hey! I passed! =)

he didn't grade so harsh on tests..many times i thought i got a c, but it turns out to be an A- :) one thing funny about him is that he always say: "yes or no, then go on say YES" i mean if students don't reply yes, that means most of us don't get it..and the answer should be NO...overall, i think he is doing his job the right way.

Those previous statements are completely false. He is one of the best math teachers I've had. He explains everything thoroughly and is always willing to help any students with questions. His tests are challenging but he goes over everything in his lectures. Take good notes, practice and you'll do fine in his class.

Even though I ended up with an A in his class, he was somewhat hard to understand. He mainly grades on how well you do on your tests, but doesn't grade your homework (it is reccommended to do the homework because it will help you do well on your tests). Other then that, he's a decent teacher, and only reccommend him if you want a challenging class.

He looks at you and ask you "yes or no". If you don't understand say no, he actually stops in the middle of the problem to explain what you don't get or sometimes even go back to the previous problem for you. He seem intimidating but really, he isn't.Therefore, any question should be asked otherwise you will be lost in that class.

Prof V is a serious & smart math teacher. He really wants you to get it, not just pass the class. He drops 1 exam and lets you use your notes/book on test. He doesn't like giving partial credit, so if you're not close to the right answer, you'll get something like 3/10. He expects you to pay full attention and doesn't like to repeat simple things.

Want to learn math from a world-class master mathematician? Then you will appreciate Professor Vayngortin. His clarity and precise methods will serve you well if you are willing to commit them to memory. He expects you to keep up, participate in class, and ask ALL of your questions, which he gladly answers each day at the start of class.

I believe he is one of the best math instructors in city college. But definitely the best for calculus. He totally know what he is talking about, he answers questions, and his tests are fair. He also doesn't make you memorize all the useless formulas; you can simply open your notebook during tests!!..highly recommended

Prof. Vayngortin deeply cares about his students. He does everything possible and beyond to help students understand material. His explanations are crystal clear. But if you are not serious about math, think twice. His class isn't an easy A.

QUIET! He speaks very low.

Professor Vayngortin is SERIOUS about calculus and he expects you to be serious about it as well. His goal is to get you ready for more difficult classes you may take at another school and he does it well. He doesn't like it if you're late or lazy. Also, he had a bone-dry sense of humor that I think is awesome, but some may find off-putting.

very Clear explanation! Not really easy to get an A in his class but you will learn a lot in calculus if you take him. i hope he will teach 110B next semester but he doesn't :(. Anyway, take his class and you can see how interesting calculus is

takes one two days to explain each new section. comes up with his own problems and then takes some out of the book. he doesnt collect homework but if you want to pass the test you should do it on your own. open to any questions and the test questions are similar to what is shown in class.seems intmidating but is really nice. no b.s kind of guy

boring teaching but easy grading i got an A in his class

I wish he was teaching 110B this sem. My current teacher's lec are confusing and I really want to drop it. I like that his lec are very uniform, he won't let people distract his lec w/off topic q's. He always asked if everyone understands, if not he would explain agian. Loved him!

Prof. Vayngortin cares about your grade more you think he does. Do your work to get a good grade. He does his more than excellently. Don't think he is mean. He appears to be, but he is the nicest person. He will explain anything and everything more than once if necessary.

Yes, he never smiles. Yes, he's got an accent. But you know what, his lectures are clear and he's willing to answer any of your questions. I came into this class thinking I was screwed based on a first impression of him but I left the class feeling the most confident i've ever felt about math. He really is a good teacher!

He might seem as a hard teacher, but he is very helpful and understandable. I took him for 110A and 110B. I wish he teaches 110C :(. Good teacher to take!

He is a good instructor.He is willing to answer your questions. His test is hard, but you will be fine as long as you did all your homework and understand it. You need to work extra hard for his class.

Were it not for Mr. Vayngortin, I don't think I would have passed 860. He may seem a bit dry and intimidating on the first day, but part of the reason I found his method so helpful is that he sets boundaries and ground rules right away. Once things get underway he is extremely helpful and kind. He is straightforward with no gimmicks.

His accent is ok. If u do the homework assigned, u should be fine. He tells u what types of problems to expect before the test. Plus, the tests are easier than the homework in textbook. Just make sure to keep up with his lecture and the book.

Pretty good, gets the job done. Definitely recommend doing the hw. Tests are pretty hard so every extra problem will help for preparation on exams. Definitely bring the book and do not be late.

Lev is a good teacher but you'll only learn if you put in the time for homework. He's always willing to go through difficult homework problems at the beginning of class. Visit his office hours! He's not there to entertain you!

Show up to class on time every time. Make sure he knows your name. There are only a few tests, he drops the lowest and also gives extra points for those who show motivation to learn. No assigned homework. So its up to you to study. I Highly rec. studying geometry and algebra thouroughly before taking his trig class. He has no time to retrain.

He clearly knows math. If you have problems you can come to him during the class and he explain. The only thing for me was that he skips steps or assume certain things when he does problems on the board which may be confusing. Work hard and u will b fine!

It is ok to use ur notes, book and calc. during the tests, but if u didn't practice enough u won't have time to finish. He gives some "not in the book" info during the lecture which most likely will be on the test, so come to class. If you work hard, ask questions and practice you will pass and get a good grade!

To me, Math is very clear cut. He tends to explain the process and then has you practice a bunch of the problems from the book. He does have a bit of an accent and seems uninterested BUT if you actually participate he has a slight spark of hope in his students and seems willing to help. Closed mouths don't get fed- have a question? Ask.

He's a really chill guy. Tomorrow is the last day of the course and I highly recommend him. Yes He has an accent(only difficult thing about this course). Get over it. He knows what to do. If you research him like I did, he has a PhD. Not many tests. Do some of the homework. Tests more difficult than homework though. Take care Professor Vayngortin!

Yes He has an accent(only difficult thing about this course). Get over it. He knows what to do. If you research him like I did, he has a PhD. Not many tests. The summer class never need to turn in homework. Tests are similar to the homework. So do the homework and ask questions after class. Take care Professor Vayngortin!

I took Math 110C back in 97. At least I studied for one test and for the final. I should have been studying more carefully. The lectures were fun because it was like being in a classroom I would imagine in USSR. The lecture is more old school. Mr Vayngortin told me that he disliked that some students appeared to be dishonest with respect to grades.
