course

Professor HalpernLeistner is a very enthusiastic and knowledgeable lecturer, you can easily see how much he enjoys the subject matter, but his class was very demanding. Week to week, the WebAssign homework, for me, averaged about 23 hours to complete. The written homework was more difficult. On average, I spent 56 hours working through the written homework problems.The third homework assignment took me 15 hours to complete (combined), but, after realizing how long it took for everyone else, he adjusted the difficulty. If you do not dedicate the time to master the subject material in his class, you will, more likely than not, struggle on the quizzes and exams. I am an Economics major, and as much as I enjoy learning calculus, this course may be better suited for math majors. Professor HL was very active on Piazza, answering questions and clarifying subjects, but he prefers to "push" students to figure things out on their own, as opposed to just clarifying a lack of understanding. I cannot attest to his office hours, but given his enthusiasm, I assume he was more than eager to aid students.

Sitting in Professor Hom's class, I could tell that she truly cared about whether the students understood the concepts she presented because she stopped to throughly explain questions students asked. Her lectures are outlined very well so that come midterms/finals study time you should have comprehensive and organized notes. Her exams are very fair so long as you do all of the practice problems she assigns as well as take the time to actually do the homework. The final was the toughest out of all her exams, but thats probably because the later material is harder to grasp and the final is comprehensive but has a definite focus on the untested materials we learned in class.

Professor Diogo is a thorough earnest professor who seems interested in having his students rigorously understand calculus while still liking it. He is not a sadistic math professor who assigns tests with averages in the 40s. He explains the material in enough detail so that we understand what to do and why, but not so much that it become pedantic. He is very helpful when questions are asked and explains exactly what wrong assumptions or incorrect logic the questioners are using. Sometimes his examples are a little long winded, but mostly they are fine. He takes the time to derive things, but if the derivations are too tedious and not that important, he may skip them. I recommend his Calculus III class. It made me like math.

Marcel is a very competent Calc III professor. The workload for his class is average, and his midterms and final are very straightforward and easy (if you have done the homework). I enjoy how he is always so happy in a 8:40am class and how helpful he is in office hours. His lectures are not boring, so go to the lectures. He explains the conceptual part of Calc III very well and I was rarely confused. You don't have to be smart in math to get a good grade from him. Just put in an honest amount of work, do his assignments, and memorize some formulas to ace the midterms. He assigns weekly problem sets and for every problem set, there is one or two tricky question(s). If you are stuck on a homework question, don't hesitate to go to his office hours! I highly recommend Marcel for Calc III.

Marcel Nutz is a solid choice for Calculus III. Having sat in on Maria Cuetoâ€™s class and having had Alex Drewitz as a sub I can say that I clearly prefer professor Nutz to both of them. While Nutz might not be the most energetic professor, he has his own personality, and he teaches you exactly what you need to know in clear, organized lectures. I appreciate how he focuses on Calculus being conceptual rather than formulaic. For example, while talking about distances in 3D space, he emphasized that all these formulas come from projecting one vector onto another, and this was extremely helpful in understanding and remembering the formulas. I also appreciated his use of erasers, rulers, etc. to demonstrate 3D principles, which is helpful for someone like me who doesnâ€™t always understand 3D drawings. His handwriting is mostly legible, but if you are confused, you can always ask him to clarify what he wrote and he will happily do so. If you donâ€™t understand him in class, go to his office hours. I found him helpful and reasonable in office hours. He doesnâ€™t give practice exams but the harder book problems are on par with the exams. He does a good job of reviewing and emphasizing what you need to know in the class before exams. The exams increase in difficulty, as does the material, but all of them are most definitely doable. On top of that, his curve is quite generous. About half the class stopped coming to lectures eventually, and you can definitely learn what you need from the textbook, but I find his lectures more helpful than reading the textbook. Overall I think Nutz is a solid Calculus III teacher who provides you with a good understanding of the material in a relatively low stress, fair, class.

Sachin is a pretty good lecturer, and puts all of his notes on the board in a very logical and concise manner. He provides example problems which are helpful to look at before the exams because they are often similar to the problems on the tests. Although he is not the most engaging lecturer, he has his fair share of funny oneliners when answering questions, and I find that even if you zonk out but copy everything he writes down on the board, you can make sense of it when you look at your notes again later. He has a slight accent, but it is easily understandable. Also he is NICE at drawing 3D shapes... Much of the exams is straightforward, but there are usually one or two "reach" problems where you have to tackle something you haven't seen before and have to do some tricky thinking to figure out.

Deopurkar is genuinely a kind person. He is approachable during office hours. But contrary to the over exaggerated reviews on culpa, his teaching style is if anything, average. I think people are just blinded by his adorable personality. Another reason why people are raving about him might be because the math department in Columbia is pretty sad when it comes to teaching undergrads. Yes, do take classes with Deopurkar, because you can do a lot worse. But don't expect him to be the best math teacher either, like some of these reviewers are claiming. I studied both calculus II and III with Deopurkar. Somehow I found his calc II class more difficult than Calc III. I'm not sure why this happened because a lot of people find calc III more challenging. Also, expect exam questions that require you to think outside the box. He gives some difficult exam questions, which in the long run, is good for you if you are planning on majoring in the sciences/engineering/math. However, if you're a premed student who cares a lot about your grades, I suggest that you consider carefully before signing up with him. Definitely not a guaranteed or easy A even if put in a lot of hours studying.

I had him at 8:40 AM, so he was always a bit slow to start, but by the time he finished his daily espresso he had bursts of enthusiasm towards the material(which was occasionally interesting). His teaching is standard and organized. Talk about a topic, do a couple of examples increasing in difficulty. He had a slight accent that I found easily understandable. I always sat in the front, but his voice seemed quiet enough that it might not reach the back of the room so well. His answers to questions were always clear. No webassign, woohoo! 7/10 Would take again

Yes, yes, yes. This is what I'm talking about. Harvard didn't raise no fool. This guy is too good to be true. Crystal clear, insightful, with some focus on why things the way they are, very very friendly and appreciates ANY question, I repeat ANY question. I mean there were stupid questions and he would try to answer and reapparoach from different angles. This is the art of teaching mathematics. While calc is some prereq that everyone has to take, so your not going to have an outer body experience, but he really impressed me. Don't get me wrong, this is not an easy A. You will learn though, and learn the right way. The exams are so well written, creative but not rediculously hard. Good amount of homework, but right outa the book. He is very approachable during office hours and is very very funny. We need more Anand's in this world... And on top of all this, this master is so modest that when our class ended and people just had to applaud him because they have had their fill of ivy league crooks, Anand was so shocked and appreciative, he didn't realize how brilliant he was... haha.

Basically, Anand Deopurkar is one of the best calculus professors on campus. He gives very clear and concise lectures, which I find key in any calculus course. His problem sets and exams are very simple and straight forward. He gives a few practice exams to prepare for both midterms. It is a very easy class and requires minimal effort/work. As a math major, I found it to be an easy A. Looking forward to taking future classes with this prof!

Jen Hom is an ok professor. Not the greatest but not the worst. Her class gets kinda boring at times though. The material itself isn't really hard. There is DEFINITELY a lot of material though, so I would not recommend cramming for a test on the night unless you're a math whiz or already learned this material in high school. Be prepared for a lot of hw if you want to take this class. And by a lot, I really do mean A LOT.

She is an okay professor. She usually just reads from the book and copies it to the board, without making any of the material interesting. Instead of doing examples on the board with the class, she just copies whatever is in her notes to the board while not engaging the students in the problems. If she slowed down her pace and tried to involve the students in the class, she would be a much much better professor.

Very nice woman, but not the best teacher. If you're not in the first two rows, you have no possible chance of hearing her. She talks directly to the board as she writes down problems and speaks very softly. My class was about 70 people, so if you didn't arrive 20 minutes early to snag a good seat, you were screwed. She also got lost doing her own preprepared problems. There was a class on arc length (which isn't the most difficult concept) when she spent the entire class trying to figure out a problem. She finally asked if we would try it at home and explain it to her next class. She often said memorizing formulas was not necessary because most of the time, you can just figure them out. Unfortunately, she would take up half of our class time trying to remember simple formulas, like the cross product. I ended up learning mostly out the book, which didn't prepare me for the exams that well. The problems on the homework are all very simple. Exam questions are generally not reflective of the problem sets. If you're a math genius or someone who already took calculus III in high school, you'll do fine in this class. If you actually need to be taught calculus III, however, try a different professor.
