He is a really smart teacher who knows what he's talking about. he's very into theories of math which can be very boring!!! if you are a hard-core math person, then take him. one good thing about him is that he makes the midterm and the final for all calc classes.

Makes the final for all classes, but his midterm is the hardest, as well as the quizes. Hw is the same for all calc classes so there is no way to avoid that. If you're good at calc and understand the material he presents you should get at least a B+.

I really enjoyed taking Calc I with Leingang. Though I didn't get a very good grade, that was not his fault by any means. Makes lectures really interesting: interjects math-history and even pop-culture trivia in them while not losing sight of teaching important concepts. Really friendly and approachable. Highly recommended!

Leingang is an amazing professor. In a class of 200 students, he actually takes the time to try and get to know everyone personally. He tries to make the subject material interesting and sometimes he incorporates his daughter which is adorable. He assigns 1 homework per week and he has a midterm and a final. He's awesome! Don't hesitate to take him

Leingang is truly an amazing professor. If you have to take calc, make SURE you get into his class! he made calc lecture somewhat interesting, and has great powerpoints that he posts that you can study off of later.also, he's super funny!

I liked his powerpoints - saves a lot of time and easy to review later for exams. hated Webassign - hwks are very time-consuming and not necessarily reflective of exams. He's no Jaime Escalante, but the man is very passionate about teaching calculus. Go see him during office hours and get to know him.

His class is interesting. It's not hard to understand and the quizzes are easy.

His lectures are very interesting and he is very hot;)easy A without worries

He really knows his stuff. Powerpoints are very clear. Spends too much time on origins of proofs and deriving them. All we want to know is how to get the right answers! The Web-Assign is extremely time-consuming but you can't avoid it. HW is graded strictly and the quizzes are short and a little tricky. Just a midterm and final. Best CalcI can get.

He's brilliant and funny. Reminds me of Ted Mosby from How I Met Your Mother. He is the head of Calc Prog, so he writes the finals. But both the final and midterm is hard especially the conceptual word probs. He cares about his students.Very helpful and approachable. He would respond to e-mails. There'll be quizzes. But again, brilliant,choose him.

nice and funny guy. expalins things well

I recommend him if you have taken AP Calc in highschool. Otherwise, he is really conceptual and you'll have to teach yourself most of the stuff. He uses webassign for homework (in addition to written hw) and that's basically death. If you know calc, you don't have to go to class. Not the best, but at least you can understand him.

Intelligent and clear in lecture. Class, however, is HARD. Especially calc2. Very concept heavy. Seems more geared towards math majors than anyone else. Webassign (online hw) was torture. So was written hw. Had to do proofs for hw in calc2! I say avoid, there are prob easier profs out there

He's a smart guy, but his downfall is that he teaches straight from the powerpoint, so if you don't kno how he got from step 1 to step 2, you'll be pretty much lost as to how he got to that answer. My class did horribly on the final, therefore the curve was pretty generous, although he doesnt curve all the time..Prior AP Calc is a must to get an A

Best. Professor. Ever. --> Take him for the upper level Calculus Classes and you will not regret it. You get the grade you deserve and he does everything he can to help you learn.

Professor Leingang is one of the best calc professors ever. He's clear in his lectures and uses worksheets to get students involved. He's dorky and quirky in an adorable way. His tests/quizzes aren't unfair or extremely difficult. I learned a lot from him. Highly recommend! Do whatever you can to get in his class. :)

His teaching techniques makes sure you learned the material before you leave class. After he teaches a section, he hands out worksheet to do then he calls on someone to do it on the board and goes over the answer. He is excellent, funny, and answers all questions.

I do not know how he got his PHD from Harvard. He is not good math at all!! He can only cover what text book says, but cannot explain anything complicated. Even though he is nice and approachable, he is not a genius in math. No wonder he does not do any research now, simply teaching calculus....

By far the best professor I have had in all of my years at NYU. He is extremely intelligent, approachable, and caring. He wants all of his students to succeed and understand the material. He does an excellent job of explaining the concepts and getting the class involved through worksheets. You will leave this class being amazed with him knowledge.

Flexible, committed, and knowledgeable. Requires participation - which is kind of difficult for a calc 3 lecture. If you are there to learn and work hard you'll do fine, he is very understanding and helpful.

In class: this is how you integrate. Exam: find the total perimeter of an infinite ever-growing fractal in series form. What even.

The class structure is awesome. You learn the lesson through clear examples and then do a worksheet about what you learned/harder examples. Quizzes and exams are really straightforward. The only draw back is he does written homework through web assign so you have to scan in your work to your computer.

Quizzes every week, but he drops the lowest 2. The homework is ridiculously hard, but he grades pretty leniently and drops the lowest grade. Grading isn't too bad. Just pay attention and take good notes.

Leingang is definitely one of the smartest and most friendly professors I have had so far. Lectures are crystal-clear, and office hours are helpful. However, his major downfall is assigning ultra-difficult problems on both the written assignments and midterms. I would only recommend him if you're really into math or wanna tackle difficult problems.

Great professor, but he gives extremely challenging exams and homework. Somewhat of a tough grader. He speaks really fast and assumes previous knowledge in Calculus, so if you don't have a strong interest or foundation in Calc, you will probably have a hard time.

Very clear in his explanations but gives ridiculously tough test questions.

Lectures were always very well planned and structures - his notes were abundantly clear and were always followed by practice worksheets and in class exercises. Homework was challenging but doable.

He was such a fun teacher. He had a lot of fun with the subject he taught. Even though he would let out the occasional corny joke, I still laughed. He's the epitome of a dad. He was very helpful with feedback and made sure you really understood it. He was very accommodating with office hours. Had him for Calc I and II. Would recommend

Leingang is a seriously underrated prof. Sure, he gives a decent amount of work and he makes you use LaTeX, but if you go to class, do his homework and pass his quizzes, you'll be in good shape. For a lot of profs this is NOT true. Not to mention he really cares. He'll go out of his way to help you and puts so much effort into teaching.

Honors Calc III is a lot more about the conceptual than the practical, so be prepared to study calculating examples on your own in the book. However, Leingang does a good job of getting weird concepts to be understandable. Hard-ish weekly quizzes and homeworks, so study up and learn LaTeX. Make sure to participate and go to class.

Leingang is a great teacher, and if you're some one who likes math, you'll find the class quite fun. (Discrete Math). Weekly quizzes are straight from the assigned textbook problems,HWs will usually be from the book but must be coded on latex (time consuming). Exams are easy! I've heard that he' s really tough on his hon calc 3 class though.

This professor gives very clear explanations to even the most complicated concepts. His classes are very organized, strictly following the syllabus. Grading is a bit strict but definitely fair. Homework are carefully selected, very entertaining to work with. Definitely don't regret taking his course.

Like his class in general. He is a kind and easy-going teacher. You may also learn a lot about math if you take his class frequently. Homework is not too much. The only frustrating thing is that Latex is a mandatory requirement, which costs lots of time.

Prof. Leingang reminds me of a grade school teacher. He marked attendance, graded participation, had student do Do Now questions at the beginning of lecture, and remembered every student's names. He manages to make the complex concepts of Honors Calc III digestible. However, midterms and weekly quizzes were rather difficult.

Pretty good professor. Good at helping to understand the material, is accessible, and kind. The workload can be sometimes heavy but is def manageable if you manage your time correctly. Test are hard but fair. Weekly quizzes are not as hard. There are also some easy A assignments he gives that allow you to boost your grade too.

Professor Leingang was a nice lecturer. Those who participated all thoroughly understood concepts. He has a lot of small assignments (more so to check understanding) and is really good about helping students and applying concepts. Honestly, I have no clue why some of these other ratings are so harsh to him.

Professor Leingang is best suited for individuals who are truly interested in math. That being said if you are looking for an easy math class where you rinse and repeat formulas, this is not the class for you. I think many of the bad reviews are biased by the difficulty of discrete math, not Professor. No one is just immediately great at proofs.

Bad studying habits aside, this class is definitely manageable. MATHUA120 can be dry since it's mostly getting familiar with mathematical language, but prof Leingang made it interesting where possible. He's really tolerant and understanding, so I can imagine enjoying his class a lot more for another math class (like calc). I would take him again.

Professor Leingang gives different kinds of assignments to help improve all kinds of learning skills. Discrete math is definitely difficult, but these assignments help a lot. They improved my ability to write proofs and learn from textbook to a huge extent. Attendence is not mandatory, but you will do much better if you really come to class.

A lot clearer in lectures than previous math instructors. He has a good vibe and tries to get to know his students. I took a medical leave and he was very understanding and flexible with me as I got back on track. Course material is challenging but he explains it in a way that makes it as easy as possible.

He is a good professor and nice person, but he is a really tough and strict grader. The rubric is not clear at all, I got points taken off for not assigning pages when turning in works on gradescope, not simplifying fractions, or didn't put fractions into decimals. Also assigns heavy readings that make going to lectures pointless. 4 quiz per week.

You will do well on his class if you figure out the content in his lectures.

Super caring and friendly. The friendliest professor you will find at NYU. Only tests on whats taught. Very accessible and passionate guy. I love him

Truly wants to get to know you as a student. Helpful during office hours throughout the week. Lots of time is required/effort to do well in the class if you aren't naturally good in math, but he sees your efforts. Super rewarding because you'll learn a lot. Exams are created super fair if you keep up with material from slides/past exams he posts.

He truly cares for his students, and provides fair exams. He explains concepts clearly and in a manner that's easy to understand. He gifts you with a strong foundation in Calc and in Maths in general. He will challenge you, and patiently explain to you until you understand. He, inspired me to pursue Maths. Don't hesitate to take him.

He was cool. Super funny if you like dry humor. The content of the class we quite heavy but he explains everything fairly well. Not a bad choice for a Discrete Math Prof. One con was the pre-quizzes due before class, but luckily they force you to learn and they're graded by completeness. Had a lot of office hours and was very responsive by email.

His lectures are inspirational, diving deep, and also very hard. His course involves a lot of professional mathematical knowledge and lets you have a profound understanding of every aspect.

No doubt that calc 3 itself is really hard.. Prof. Leingang actually tried to make the dull material more fun and more engaging in class. Weekly written homework + weekly in-class quizzes + 2 midterms and 1 final. Not hard if you are interested in math. DO go to his office hours; he replies email very fast (within a day normally)

2 post quizzes and 1 written hw per week is a lot but it actually helped me a lot to understand the material way better. The lecture would not make sense if you dont put time into the textbook readings and exercises. The class itself is fun but is indeed challenging since it is so different than calc or any other math classes ive taken before.

He explains everything very well and clearly, and he is very responsive and caring. But he is a tough grader. 4 quizzes per week, strict grading criteria of polished proof, and seldom give full participation grade.

Definitely take his class

Meticulously organized. Always posts some enrichment material after lecture on Brightspace. Goes above and beyond the textbook at times, although lectures mostly regurgitate said book. Unfortunately has a tendency to neglect struggling students.

Prof. Leingang is the best professor at Discrete Math I've seen! You can attend the morning class via Zoom and he'll still count your attendance. The lecture typically starts with a funny poll, and the contents are interesting and easy to follow. The course is well organized. Take him for Discrete!

This class hit me like a truck, but professor Leingang was great. He's very passionate about math and energetic in class. There is a lot of homework to help with practice as well as weekly quizzes that I tried my best to prepare for and didn't do very well. He does have a lot of office hours which can be helpful if you have a specific question.

He's great at teaching and very nice. He actually answers questions on the discussion boards & he gives pre-class surveys where you can ask more questions. That said, tons of work, quizzes every class, & you have to read the txtbk to do the surveys. Lectures sometimes have extra info not in txtbk that you need to know. Curved a lot in the end tho.

For the people who say Calc 3 is easier than Calc 2, it is not. I personally would not recommend the YT videos he has in brightspace. Instead, learn a bit about the general topic on your own, then look at the textbook. Sometimes, trying the WA can also help. Put a genuine question into the pre lecture survey. Finish assignments a day before.

He's an amazing person and lecturer. Everything is so organized in lecture. A lot of work tho, you have quizzes before and after lectures. However, they are super helpful. Lecture is proof heavy, and a lot of definitional questions on exams, and some of them are tricky. Amazing professor! Take him if you love math!

good professor, pretty kind and caring about his students. tests are surprisingly difficult, averages are very low. doesnt seem like we're quite prepared for what's on the exams in class.

1. Take good notes. Instead of answering questions, the professor and TA's often respond with “refer to notes” 2. Everything's in scope for exam, including recitation/hw questions that he legit copies pastes into exams 3. Attend all lectures cuz he goes over concepts that sometimes aren't in textbook and like I said, it'll be in scope for exam

A great professor for a tough course. It's a lot of work, but he ensures to keep lecture information valuable, and it is all relevant to what you will be tested on. Hard, but fair.
