He's a good prof even though his jokes can send one off to sleep. He knows his subject well and is very helpful outside class also.

FABULOUS teacher. Practice exams are almost exactly like his tests. HE explains everything clearly and grades fairly. One of the best teachers that i had at Tech my freshman year

He did a great job at explaining the material and he was always very willing to explain things in such a way that were easy to understand. His tests are extreamly fair! One of the fairest teachers here at tech. He did an amazing job at teaching the course, I feel that I learned something.

His lectures and exams are very straight forward. As long as you go to class and recitations and spend some time studying before exams, you should be fine.

He is a very good teacher. Unlike most Tech teachers, he actually TEACHES! He explains the topics well and provides you with notes so good that you won't even have to touch your textbook. He posts previous exams online that are just like the tests he'll give you in class. He's one of the fairest teachers I've had at Tech. Highly recommended.

Great prof, his tests are exactly like his old ones which he posts online. He also provides typed notes which are very useful. Prob the best prof Ive had so far at tech. Just study his old exams and youll get an A for sure.

His lectures are entertaining. He explains the subject very well and he was one of the first math teachers I've had that I could actually understand through their accent. Old homeworks and tests are pretty much all you need to do his new homeworks and tests. Definitely take him

Awesome professor. He's funny and entertaining yet he's thorough and easy to understand. Highly recommended.

Easy, funny, and excellent teacher. Very rare at Tech. No need for the textbook. All notes are online. Gives you a month to do homework, which is almost exactly like previous homework online. Study and do the old tests a night or two before the test and you'll do fine. The final is beastly long, but not that difficult. Bottom line: I love this man.

Awesome teacher. Online notes, clear and thorough teaching, tests and homework are very similar to previous years. Makes math very entertaining! Very easy to get an A, as you can drop lowest test score. VERY Highly recommended.

I seriously love this man. I had him for one of the hardest classes at Tech (in my first semester no less), and he made it easy and interesting, and I feel like I learned a lot. I never missed his lectures because they were just too funny. Thank you Professor Lubinsky!

Great teacher! He makes calc 2 simple b/c he doesn't go so deep into theory like most other calc teachers do. The class is straight forward; he works lots of examples and tests are almost exactly like practice tests. A little awkward one on one, but oh well.

Easy to get an A with. What you get from his class depends on you. Tests and exams are not challenging at all and you can get by without knowing much (this is my personal opinion). But I do think that he does a good job. Lots of examples are offered for you to grasp the concept. BUT I MUST EMPHASIZE YOU CAN GET BY WITHOUT LEARNING MUCH.

MUST GET THIS PROFFESOR. You can actually understand him. He tells jokes during class and makes class actually fun. Attendance is not mandatory because he gives the notes online, but i recommend going. Very helpful, does many many examples in class. Tests are more problem based. He post old tests that are similar to his own. Very Good Teacher.

Awesome professor and a great teacher. Explains things very well and provides many examples which can be found helpful for preparing for the tests. Also, tests are similar to old tests, which he posts online. Would recommend highly for any class he instructs.

TAKE THIS CLASS. If you are considering taking calc 2, no one tops Lubinsky. His lectures are clear and detailed and you'll actually understand it. Tests and homework are fair and resembles the previous terms' and are all online.. same with notes. One of Tech's finest.

GREAT TEACHER, funniest teacher of all time...very easy and interesting if you plan on taking calc 2 he's your man

Very good notes and easy tests (except for the final which is the hardest test I have ever taken).

Great professor. Was always entertaining and could explain the material really well. One of my favorites. You HAVE to get him for Calc 2!

Really enjoy going to class even if the lecture notes are online. Homework is tough but it really prepares you for the tests. Previous exams are available and most times resemble the tests. Highly recommend taking it. (can't say yet for the final as I am currently taking his class)

BEST TEACHER AT GEORGIA TECH HANDS DOWN. I learned a lot from him. Throws jokes out during class while teaching. Do anything to take him, or just sit in on his lectures. Do the previous practice exams, they will help with the exams. Awesome professor!

He is so adorable, he worked examples in class and gave practice test that were almost the same as the test we would take. Homework counted for more than the test itself did.

One of the best professors in gatech in terms of lecture quality. He delivers one of the clearest and most well-organized lectures. However, don't expect this class to be an easy class. The tests and homeworks are not easy, and you have to put some efforts in it.

He is definitely my favorite calculus professor at Georgia Tech so far. His notes in class are very easy to follow and he has practice homework and tests online which are the exact format as the homework and tests. The homework was a little challenging at first but this class overall was very good. I would definitely recommend Lubinsky's class.

Great Professor! Try to get him no matter what!

He is really good at teaching. His homework is original worksheets, not from the book. They are the most difficult. I rarely went to class, but got an A because I made a 114/125 on his final.

Lubinsky was an absolutely awesome professor. I had him for Calc II in Spring 2012. The material is really difficult, but I feel that he did an excellent job of conveying the methods necessary to solve the problems. It is evident that he has a deep understanding of the curriculum and is more than capable of teaching it.

Very good professor, with a great personality (and accent). The class is still hard though

Get Lubinsky for Calc 2! He is a very good(albeit fast)teacher and he's even pretty entertaining. This class will not be a walk in the park by any means, but you get to drop one of your tests, which is extremely valuable. Long homework packets, but I'd absolutely take his class again.

great professor. Knows what he is teaching. Like to have him on my next course

Great Professor. Teaches concepts as best as they can be taught, so it's practice that makes it stick. Tests are hard. Written homework assignments, which are graded, are harder, so if you do the homework before each test you should be fine for the tests. Definitely possible to get an A if you try.

He was the best math teacher I've had. He was amazingly clear about the content, gave plenty of examples so that new topics were easily understood, provides practices tests that are 90% of the actual tests and he keeps you entertained throughout the class while still teaching effectively. If you have the opportunity to take his class, DO IT!!!

Professor Lubinsky is one of the best professors I ever had. His lectures are very comprehensive and he is very thorough and helpful. I actually ended up learning a lot in his class and really enjoyed it as well. I would highly recommend him.

Phenomenal professor! He delivers well-organized, coherent lectures with plenty of examples and just the right amount of theory, plus he's absolutely hysterical. His class is a lot of work, and his final exam is extremely difficult, but I feel like I know the material extremely well. He is a MUST HAVE for Calc II!!

This man is the bomb dot com. He is pretty clear and helpful. His reviews are nice. Go through Piazza if you have questions. His South African accent and stories kept the class pretty interesting. Expect to hear either "You're Georgia Tech students!" or "This isn't the Outer Okefenokee School for Wayward Boys and Girls" during every lecture.

He was a great teacher and made the class very interesting with his sense of humor. The class material is very difficult and it is hard to catch up if you miss a class, though the pop quiz dates are usually pretty predictable. He gives a moderate amount of homework. He says he is making tests harder next year.

Great professor, lectures are very helpful and interesting since Lubinsky is a pretty funny professor. Tests and homework are fair if you understand the material. The only downside is that every time I'd visit his office hours to ask him a question about an assignment it seemed like he was kind of annoyed that I was there.

I took MATH 2552 online by watching Doron's lectures and he was great. His lectures are very helpful and he posts notes to each one on T-Square. Tests were not very hard. Just do the homework and you'll be fine.

As long as you pay attention in lecture and you do the homework, you'll do great. His lectures are very clear and easy to understand and he's funny which helped make it more interesting for an 8am. The only complaint is that he is hard to talk to outside of class, but he is a great lecturer.

His class was very enjoyable, because he taught the material in a very clear and concise manner, made it clear what was necessary to succeed in his class, and was funny throughout the lectures.

Fantastic professor. Class was very enjoyable because of his lectures. Prepared us well for the tests with the combination of lecture and the homework.

This man is a memelord. Be ready to hear "You're going to Georgia Tech" or "This isn't the Outer Okefenokee Swamp Community College for Wayward Boys and Girls." This class was an 8AM but he was funny and engaging enough to make that okay. I originally didnt watch any of the lectures, but when I did the class was substantially easier.

He taught the material well while managing to be funny at the same time. He was very clear about the material on the test, and the examples in class were representative of the types questions asked on the exams.

Awesome professor that teaches the material very well. His tests are fair and if you do the homework you will be fine. However, his office hours are useless. He was more focused on the cricket match on the TV in his office than helping us (well he is from South Africa)

This is a difficult class, but Professor Lubinsky manages to make it fun and engaging. Tests are straightforward if you do the homework and go over practice exams. Definitely try to take him if possible!

Amazing professor. His lectures are very informative and enjoyable - I only wish I had attended more of them. Honestly, go to class, listen to this awesome professor. His analogies and stories are very high class, and if you do the assigned work too (yup, there's online homework), you will be fine. After all, we are Georgia Tech students. :)

Hilarious professor and great lecturer. Explains concepts clearly with sufficient practice problems. His typed notes are also a big help and very detailed.

Took this as a distance class last semester. The guy is an amazing lecturer, and the class is fairly easy. Print out typed notes, follow along with lectures and study the night before tests and you'll get an A. He did say there would be a curve, but it ended up being something like a tenth of a point, so keep that in mind.

Lubinksy is honestly pretty good. I definitely learned a lot in class. The tests were pretty difficult and long. When I was struggling to finish tests, I reached out to him for help, but found him to be very unhelpful. However class is kept engaging through his humor. Not a bad teacher, just really difficult.

I took the class as a distance student, and Professor Lubinksy was really great! He jokes much about "Okeefenokee college" or something like that.. but he really teached the material well, and I felt well prepared for the tests! Just do the homework, and you will be fine..

Lubinsky is a great professor. I would recommend him to anyone who needs to take 2551. I took this class as a 5 day a week 8am lecture and do not regret it at all. It was worth the 8am. However, if you don't feel like going to lecture, you don't even have to because he uploads his lectures online! Tests are very similar to the practice tests!

Great professor with humor. The class was 8am everyday so I didnt go that much but it didnt hurt me because he posted the notes online. Study the practice tests and you'll do fine on the test. He drops 1 of the tests but he intentionally makes one of them hard bc test 3 had a very low average. Final was one of the hardest things I've done at Tech.

hilarious professor. i love his sense of humor and it was the only thing motivating me to get up at 8am to go to his classes. his lectures are incredibly easy to follow and useful. homework can be tedious and the written portion of the final is difficult but tests are easy as long as you can do the practice tests

Do WHATEVER you have to do to be in Lubinskys class! He really knows whats hes talking about. Hes super organized and makes 2551 relatively easy. His practice tests are basically exactly what his tests are. I promise its definitely worth getting up even though its an 8 am class. Plus hes pretty funny.

He made the class (which felt like drinking from a fire hydrant, btw), be manageable. He made it make sense. A great professor.

Lubinsky is an all around incredible professor. He explains concepts extremely clearly and is very specific about the expectations for the class. He also keeps lectures interesting with personal anecdotes and occasional self degradation. His tests are rather difficult, especially the final, so be prepared to study hard.

It would be better if the class weren't at 8 A.M. Lectures were good, but I was always tired especially at the end. The final had a lot of new material on it that brought my grade down.

Dr. Lubinsky is super knowledgeable about the material in MV Calc. His lectures are great, but the material of the course is tough especially the second half. The practice tests are almost exactly like the real ones. Do the homework to understand everything better, and try to have a high grade before the final because the final was really tough.

Professor Lubinsky was absolutely amazing at teaching. Its a lot of material to cover, but he made every topic seem like a breeze. He stays upbeat and energetic throughout the entire lecture and never made me want to fall asleep, even at 8am. 100s on midterms was definitely doable if u study. hw is a bit tricky and the final was truly devastating

Lubs was legendary; tough class (lots of hw and crazy hard tests), but you'll do well if you go to lecture and do the recitation worksheets. Easily the funniest professor too; I personally never read the textbook, but many do. He's also always willing to help if you need it. All around 5.

Wonderful choice for MATH 2551. So caring and explains tough concepts well. Never feel bored in this class because of he jokes all time, though not everyone gets it. MML Homework is long; tests (4 midterm + 1 final) make up 90%, but with lowest dropped. Careful, do well on midterms (90+ possible if study) not to sweat on the final (really tough).

Lubinsky really works to make sure students understand the "motivation" behind the concepts, not just the formulas, and that makes the class much more enjoyable. Hegenuinely cares about students and will help you if you ask. The final is difficult so study hard and do as well as you can on th emidterms.

Lubinsky's lectures are usually worth going to, but he does post lecture notes online for every class, so don't stress if you miss. Tests are pretty fair, but the final is definitely a lot tougher than the midterms. Homework is online through My Math Lab and pretty helpful for studying. Definitely a good teacher and an interesting dude. Worth it!

Lubinsky is worth the 8 am; his jokes make waking up early bearable. He is great at explaining material, and he also posts his notes which are VERY helpful. Exams are generally fair, but the final is difficult! Overall, he's a solid choice for Multi.

Professor Lubinsky manages to make one of the harder and dryer math classes bearable and at times enjoyable. Midterms are not too bad as you are able to drop your lowest one. In my case I did really well on three and absolutely bombed the other one. The Practices midterms are helpful. The Final is very hard so try to come in with a high grade.

Class is very difficult and has no leniency when it comes to the quite long homework assignments

Great professor. Funny dude. Always willing to help when you show up at his office but has NO clue how Math Lab works so keep that in mind. Posts lecture notes. If you want to do really well Id read up on that one sad dog movie because it seems to be his favorite film, lol. Final is HARD, try have a solid grade beforehand.

Lubinsky is by far the best professor I've had so far at Tech. Lectures are fast paced, but he does an excellent job dissecting a difficult subject into exactly what you need to know. He also includes hilarious stories and comments in his lectures that make it worth the 8 am. Lots of tough homework, but our lowest test was dropped. Hard final.

Professor Lubinsky's teaches well, and is clear on what will be on the test. His first three tests are fine (mirrors the practice test), but the fourth (online due to the pandemic) is challenging since there's no partial credit. However, he is not so helpful when you have questions (does not respond to piazza posts with care).

He was an amazing lecturer for multi. The class is very tough, but he made lectures enjoyable by telling funny stories about his dog. The tests are very fair if you do the practice tests, and he lets you drop your lowest exam. No quizzes. So much respect for him as he deals with a lot of crap from dual enrollment kids on piazza.

Lubinsky made the 8AM worth it, and tests weren't too bad if you work through the practice exams and hw problems. However, sometimes his piazza answers (when he did answer) were kinda rude, but he was definitely the best at explaining concepts for this class!

You are GEORGIA TECH students, you go to **BIG** school! Will miss hearing this :(. The tests can be tough, (especially w/o partial credit when online), but there is a reason why everyone wants to be in his section. This level of difficulty is to be expected as we do not go the 'The Okefenokee School for Wayward Boys and Girls'.

Lubinsky truly makes lectures worth it. He is funny, light-hearted, and great at conveying the material. The concepts he teaches are not hard to understand, but the calculations he makes you perform on tests can be very rigorous.

Lubinsky is a great lecturer and thorough note taker. Class is engaging, but he does post notes on each lecture outside of class, and it's even better than the textbook. The switch to online classes caused some changes, but the most difficult aspect of the class is that it's only homework, midterms, and the final.

Very difficult class, but completely worth it for his witty jokes and amazing personality!

Prof. Lubinksy is the best math professor I've taken at Tech so far. Somehow he makes writing with a bic pen on a white piece of paper work better than any professor does. He's also very funny. Definitely do take him if you can.

MATH 2551 was the most brutal class I've ever taken at Tech, so I suppose I was lucky to take it with professor Lubinsky. While he was frustratingly uncompromising as the world transitioned to COVID life, he was always quite funny and a great, if not very fast lecturer. This course will be tough either way, so you may as well take it with the best

His lectures were very engaging and he provided a lot of examples for every subject, making sure we always understood the material correctly. Whenever I had an issue, I would just email professor Lubinsky; and he was always helpful, taking care of our metal health at all times.

Professor Lubinsky is great. He teaches by explaining and writing notes by hand at the same time, and then he uploads them as well. His lectures are great, and I would highly recommend attending them. Watch the lectures and do all the homework to the best of your abilities. The class may not be the easiest, but an A is still manageable.

The funniest professor I've had so far, and one of my best experiences at GT! His jokes keep me incredibly engaged throughout the lecture which already contains thought provoking and interesting concepts.

A+ when it comes to lectures, C- when it comes to communication. Sit in the front and laugh at his jokes, even when they're really really bad, it makes him more approachable.

Funny, kind-hearted professor who is very knowledgeable on the subject matter. Lectures and homework can be long but lead to success in the course. Homework and easy quizzes leave some room to get an A even if you aren't stellar on the tests. Favorite professor at Georgia Tech so far!

Professor Lubinsky is a great lecturer who throws in mostly funny jokes whenever he can. Although there is lots of homework, it is great preparation for the tests and (open note) quizzes, and it allows you to keep a good grade while not having to get all As on tests. He is one of my favorite professors at Tech so far.

lectures are very old school but amazing. prepare to do a lot of homework, but expected for a 4 credit class. his midterms are very similar to the practice tests he posts and reviews. pay attention in class and you will be fine.

Very funny but also more or less effective instructor. Hard exams. Long and frustrating homeworks but multiple attempts allowed so ultimately easy points.

Professor Lubinsky's multi class was a good 4 credit hour course. The homework takes a while, and the class requires a diligent effort, but it is very clear was is required for an A. I would sign up for him again in a heartbeat due to his inspirational nature and witty math jokes!

LOVE Lubinsky! I took Multi in high school but decided to take it again and it was worth it. The class was easy to me but I already had a foundation. Lubinsky is hilarious and has so many fun stories. Please engage with him, you won't regret it

Dr. Lubinsky is an entertaining yet informative lecturer. Definitely feels like a 4-hour class as it can seem pretty heavy with concepts at times. He does a good job at breaking everything down, even though he may work a bit fast-paced. You can tell he cares for the students though.

This guy has a cute and funny accent. Don't let that distract you though... This class requires much work. Do the homework without cheating and you'll be okay. Cheat if you want to, it will be fine.

Professor Lubinsky is one of the most amazing professors I've had at Tech. Very lecture heavy, but a fair grader, and if you come to class and do the homework, you should be fine. He's also very light-hearted and loves to tell small stories and joke in class but never goes off on tangents.

Professor Lubinsky is a good professor his lectures are clear and concise, he's a fantastic grader and very fair. The class and content is difficult but he makes the content digestible.

Professor Lubinsky was a really funny and engaging lecturer and I learned a lot in his course. He was super organized too and his notes were detailed, comprehensive, and posted on Canvas. The first two tests weren't bad but the third test and final were hard, so beware

His lectures explained the material really well. He also posts his handwritten lectures + recorded lectures + typed notes for each chapter on canvas. Did all my homework (MyLab) and went to studios so found it pretty easy. Stopped going to lecture about halfway because he was kinda rude and made some questionable jokes, some jokes were funny though

He was a great professor that made the wealth of information covered in Math 2551 lectures enjoyable, with a great sense of humor. His grading was fair and the guidelines were clear, and whenever I had a question or an issue arose, he was very quick to answer and provide helpful guidance/feedback. Highly recommend!

Lubinsky does move very fast in his lectures, but all lectures are also recorded. His exams are harder than other 2551 classes, but he also goes into more depth and I felt that I came out with a better understanding of multivariable calculus than some of my other peers who took other profs.

He's very good at lecturing, but the tests can be pretty difficult in comparison to the practice tests and studio worksheets sometimes. He's still probably the best multi option because he keeps class pretty entertaining, records all his lectures, and is good at explaining things.

Taught the subject matter well and his lectures were good. Recorded his lectures as well. The tests were hard compared to the homework given.

Lubinsky is hands down one of the best professors I've ever had in my life. His lecture style is incredible, and he's a very fun and engaging professor. He also gives some of the clearest notes ever, and explains complex math in a way that feels digestible instead of overwhelming. I cannot recommend him enough.

Lubinsky is a good lecturer. However, there were lots of needlessly difficult integrals. I was very pressed for time on tests; my peers in other sections didn't have this same issue. There's lots of homework and weekly online quizzes that are only worth a quarter of your grade. Be prepared for the bulk of your grade to come from difficult tests.

Lubinsky is a great lecturer, adds humor to lectures & is a great guy. Expectations & material are clear, HW & take-home quizzes are very reasonable. If you attend studio & do the practice tests, you'll be fine. Tests are similar to practice tests, not actually much harder, just kind of annoying derivatives/integrals. Cheat sheet on the final!

Dr. Lubinsky is one of the best professors I've ever had at Georgia Tech. He's very particular with steps, and he's genuinely funny. HIs grading criteria, while somewhat strict, is extremely fair and you can tell he knows what he's doing, even if he goofs every now and then. Overall, highly recommend you take a class with Dr. Lubinsky if you can.

Dr. Lubinsky is a great professor. His classes are instructive and entertaining, and I find myself wanting to go to his classes. He is very fair in grading, and is knowledgeable in the subject. He breaks down confusing concepts into steps, and it's very helpful. I would definitely take this class again, and further classes with Dr. Lubinsky.

Professor Lubinsky is an engaging lecturer who makes complex topics digestible. While tests are challenging, attending studio and using resources like unstuck AI can help. Overall, a worthwhile course if you're willing to put in the work.

good teacher

Pretty sure I'm on track to get an A, because he's a very good teacher. He's also really funny and engaging. I like that the lectures can be held on zoom, so I don't have to walk on the opposite side of campus. Keep up with the homeworks and quizzes and lectures and everything should be good.

Very easy class, notes are detailed and contain everything you need to learn and know for the test. The test itself is very easy, easier than the questions given in the course files usually. The professor is also really chill, and grading is very lenient. They give way more credit than you probably deserve.

Doron is hilarious

Very hilarious person! Thought his lectures were a bit fast but he recorded them which was good for me since it was a 8 am class.

Amazing lecturer, very entertaining and engaging. Lectures are a bit fast paced but he records them so you can go back and watch them later. Exams are basically just like the practice exams.

I love Doron!!! He's such a funny lecturer and his materials are very accessible on Canvas. Practice tests are basically the real exam. Take 2550 with him!

Everyone below me complaining about test difficulty is lying or stupid. His exams follow the practice exams he gives out, and he tells you in lecture what will be on the exam. Entertaining professor who genuinely cares for students' grades. MML homework feels like busy work, but if you just watch all the lectures and pay attention, it's an easy A.

Compared to the four credit MATH 2551, MATH 2550 taught by Dorian is more difficult. However, his exams closely resemble his practice exams in format and question type. He is a hilarious lecturer and loves talking about his random life experiences. While slightly more difficult than expected, I would highly recommend. He's a great and funny guy.

I attended nearly every lecture and found them to be very helpful to succeeding in the course. He's also a funny teacher, and provides lots of resources (like practice tests which very closely reflect what's on the exams).
