Very nice guy. But a tough course nonetheless.

Course material was difficult, but he does his best to make sure everyone is learning the material and paying attention in class. Very helpful if you have any questions. Exams are very straightfoward, no surprises.

I have had 3 semesters at RU and he is still by far the best professor i've had...makes handouts for every lecture with examples and hints at how to solve problems. 8am lecture wasnt bad and he did his best to help students, and his best was better than a lot of professors i've had. Great guy.

Extremely great TEACHER.... Tough tests but not too hard to pass. Easy to get 100s like me if you study hard and work hard for his test. He is there to help you anytime. Has an accent but still understandable. Your lucky if you have him as a professor. Taught me so much in just one semester.

very passionate for calc and always willing to help students, wants them to absorb knowledge. very good prof. <3

For how much i hate this class, i must admit, the guy can teach, and he as a passion for both calculus, and teaching. He is a good professor, a slight bit insane at times, but he really is good.

goood teacher....sooo funny...he makes math funb with his corney jokes..lolz

best calc professor in the universe. nice, helpful, has very good handouts that help A LOT. funny as hell.

Dr.Z was so nice and very helpful. He is not only a great researcher but also a great teacher.

If you need to calc 152 try and get Dr. Z! He so far has been the best professor I've had at Rutgers so far and did a superb job at teaching. He goes out of his way to teach and really gives his students a chance to do very well in the class.

Zeilberger is probably the best professor I had so far at Rutgers. He makes math fun and gives excellent handouts. He is a great teacher and his exams come straight from his handouts. If you want to learn Calculus 2, I suggest you take Zeilberger!

Dr. Z is the best professor I've had yet as a Second-Year engineering student. Calc II is very hard no matter who you have but Dr. Z makes the experience much less painful. His lectures and morning tutoring sessions really drill the material into your head. But don't think that means you don't have to study! He's tireless in helping students.

Dr. Z. is an amazing professor..my favorite since i've been to RU..he's awesome and always there to help...one of the best!

an extremely awesome teacher, does whatever he could to help you as long as you're willing to learn; V responsible and nice, awesome handout, V passionate for math, also v energetic, makes you laugh.:love him:

Do whatever you can do get in his class, he is AWESOME! You wont regret it!

genius!

Unique personality that helps makes lectures fun to go to. He is very helpful and strives to make students understand and retain the material. It is also very hard to fall asleep in class due to his unique lecture style. He is by far the best prof i've had. If at all possible, get him as your professor for whatever math classes you end up taking.

One of the best professors one can have!! Amazing personality and he makes you love math. His lectures are just unavoidable even out of your own will!! FANTABULOUS professor!!! RU is extremely lucky to have him!! Simply a genius and a very highly recommended professor!! Take him and you will be glad you made the wisest decision ever!!

probably the best professor i have has so far. very fair, and always give you a chance to pick up your grade with some extra work. kinda a weird grading policy which i was not used to, but he is very enthusiastic and energetic. i stayed awake every day

Without a doubt in my mind, Professor Zeilberger is by far the best teacher/professor I've ever had. He is very welcoming to students effort, and is ALWAYS available to provide help and early morning tutoring. He is very enthusiastic and one of the funniest and loudest people I've ever met. He truly wants to know you as a student and as a person.

The best professor at Rutgers. Very helpful and truely cares about each student. Exams are straight forward, make sure you go to class and to tutoring.

I have nothing else to say but "Thank you, Prof. Zeilberger". You are one of the mentors who influced greatly my academic life in a positive way.

Had Zeilberger for Calculus 1 (151) Very helpful and smart professor. Actually cares about making sure you learn the material. Decent amount of homework. Doesn't curve anything, but as long as you take notes and make an effort to listen you should be fine. Highly recommended

He is one of the most enthusiastic professors I've ever met in my life.Dr.Z's ever-willing to help, extremely funny and crystal clear way of approach towards the subject makes him a wonderful professor. I loved him!!! :)

GREAT TEACHER!

Best Calc 3 Professor!!!!!!!!!!!!!!!!!!!! He even has a page with calc I, calc II, and Calc III notes of every single topic. He is too good for Rutgers !!

Best teacher of my life.

Best professor I've ever had at Rutgers and I have 3 semesters left of college. Very helpful so take full advantage if you need it. He wants you to do well so will do everything in his power to help you. Very clear on what hes teaching and entertaining.

genius and clear! Doesn't curve b/c that unnecessary. Got a 99% on the final with his teaching methodology.

Had him for Calc3, absolutely amazing. You can tell he's a genius, but he is very helpful and extremely funny. Always has review and "tutoring" sessions. If you go, do the practice exams, and do the homework you will not only do well but maybe even enjoy it!

I <3 this man. He really cares about his students & is always willing to help. He tries to learn everyone's name especially if you go to his tutoring sessions (very helpful). After you have him he is also always there if you need guidance on life decisions (such as continuing the math major). I wish I could have him for the rest of my math classes!

I took calc 3 with him and he was the man! It was an easy A. But DO NOT take Linear Algebra with him. I am taking the class right now and find it ridiculous. He puts proofs on the exams and also requires an explanation for False AND True statements. Try to avoid him if you can because there are definitely easier professors out there!

holy crap. he is amazing.

Single best professor I have ever had. Unbelievably clear, no curve, he checks homework, and theres a quiz every week, but by the end of the semester I understood the material a million times better than anyone else I knew in a different section of linear algebra, and found getting an A in the class completely doable.

Amazing teacher. Worth taking the class just for him. He is a genius and you learn a ton.

He is the best teacher I've had at Rutgers. He genuinely loves his job, he loves helping his students, and he really keeps everyone engaged in the material. If you spot a correction he gives you money! He learns his students name and is so entertaining. If you have the option to take a math course with him, do it. You won't regret it.

The best professor i've had at Rutgers. He's a real genuine guy and wants to see his students succeed. He will go above and beyond to make sure you understand the material. Attendance is mandatory and he gives non graded quizzes every class to check. Gives out a lot of practice exams/material. Give him your all and his will give you his.

Best math professor ever. Sad he's not teaching 251 next semester. He requires a lot of work but it's worth it. He's a genius. I love his method and everything about that class.

Wonderful professor! He goes above and beyong to make sure you understand the material. Although there is no curve he gives you options to improve your grade. He explains things very well and often gives you multiple ways to do it. One cool thing about him is he agrees the class is useless encouraging students to use Maple and other programs.

Brilliant professor, not a super easy class, offers free tutoring and office hours, he'll answer any questions you have, exams are similar to practice exams but a tiny more difficult, helpful handouts, but take notes in class. Calc's not easy, but if you put in the effort, you can get an A. This is not a class for lazy people. Do the homework.

Amazing teacher. Probably one of the best teachers I have ever had. He cares so much about his students and puts in effort not to only teach us but also to know us. His teaching methods helped me gain interest in calc 2 and I highly recommend taking him.

Best Professor ever! Made calc 2 so much easier to understand! He gives lots of practice problems for the exams and pulls exams questions from it as well. Go to lecture and do the practice problems and you should get an A. Super nice guy and you won't regret taking calc 2 with him!

Doron is the greatest Rutgers professor. He takes every measure to make sure his students succeed. He has "Crystal Clear Handouts" on all Calc 2 concepts, he has free tutoring sessions every week, and he has very fair exams. Above all, he is hilarious and is the only teacher I can wake up to see at 8:40AM. He is an adorable man! Take his class!

So far the best professor I've ever had. Cares so much about his students and really wants them to succeed. Attendance is mandatory. Exams aren't too bad, but the final is hard. His lectures are very helpful and he will call you out if you are not taking notes.

Greatest teacher Ive ever had at Rutgers.

Veritable Combinatorics Extraordinaire

First off, he's loud. Very loud. Had him for an 8:40 and never slept. Makes jokes and isn't afraid to josh you. Very energetic and wants you to understand the material. Don't buy the book for this class, because homework is not textbook problems, and he provides clear lecture notes online before every class.

Best professor ever!!! If you're a gunner who only cares about doing well compared to others then this isn't the class for you. BUT if you want to really understand calc, do well regardless of whether you are a "stronger" or "weaker" student, and be constantly entertained then there is no better professor.

Dr. Z. is, by far, the best math professor at Rutgers. Despite being a genius and world-renowned in his field, he is super friendly, funny, and cares about students. Only a fool would dislike this man. He also has a very nice mustache.

Even though the subject matter was algebraic combinatorics, the computer algebra skills that I learned will be very useful in my research on graph theory.

I learned so much from the challenging programming assignments.

Dr. Z is a very fun, friendly and excellent teacher. He challenged me to solve many interesting problems from the Amer. Math. Monthly. I learned a lot in the experimental math class, improved my Maple programming skills and problem solving skills greatly.

I learned how to use experimental mathematics effectively and efficiently.

Some years ago,as an undergrad at Rutgers,I attended a talk by Dr.Z on Pi Day. I still remember how much fun it was. So when I saw that he was teaching a course this fall, I returned to my alma mater. The class was challenging, fun, and innovative. Thanks to the amazing Dr.Z, I learned enumerative and algebraic combinatorics really well.

I learned so much in this class. He inspired me to solve a really difficult problem posed by Donald Knuth.

I love this class because I always learn something new. There is such a wide range of topics to immediately apply what you have learned. I greatly improved my problem-solving skills.

Amazing! Great lecture notes and is VERY compassionate about his students. He will make the effort to work with you in improving your grade. Students have the chance of curving their grade by a whole letter grade if you submit extra credit (time consuming but very worth it). He makes Calc 4 simple and is very fair with exams. TAKE DR. Z!!!

Great teacher for all types of students. His practice tests are very different than his actual tests, but prepare you well. He motivates you to work really hard and learn the material.

He is indeed a pretty impressive professor. Unlike some mathematics professor who doesn't like coding, he seems to enjoy it, which makes him special. He has some specific requirements like strict attendance of the lectures, no cell phones over the lectures,etc, which could be annoying but definitely helps to focus on the class. Exams are fair.

Dr. Z is one of the best professors that I've taken a class with. He is a real scientist. Comparing to other new inexperienced teachers in Rutgers Math dept., he certainly should be the one you choose. Although he can be annoying sometimes, he is overall friendly to students.

He gave the class 2 second chance opportunities if you did badly on the midterm exam. On midterm 1 I got 65; worse, midterm 2 I got 45. However, I got 187/200 on final exam because I worked hard and did all the practice exams and previous exams, which Dr.Z gave us to do it!!! As a result, I got an A!!! Dr.Z is the best Math professor on Rutgers!!!

His lectures are extremely entertaining. His grading criteria is very established. Also if you don't do as well towards the beginning of the semester he gives you a chance to still do well. It is a little bit hard to get an A since there is no curve but with the second chance and hard work you can do it. Awesome professor.

Best professor ever, his lectures are incredibly entertaining. Be sure to join his second chance club!

Professor Zeilberger is the best. He cares for his students. He is very accessible outside of class and he will patiently answer your questions. He also has a very clear syllabus and he gives easy quizzes. The midterms and final are a little bit tricky but never difficult. He yells at students but in a cute and funny way. Must take for 354!

I had professor Doron for linear optimization class. I loved his class. He did everything possible to teach you the material. He always was available to help and explain the material during class and during his office hours. He also provide tutoring hours for extra practice. He has his own website that is very helpful.

I took for the first time with DR.Z this semester (MAT 354). I will take further classes with Dr. Z for sure in the future. HE IS THE BEST PROFESSOR I EVER HAD. DR. Z really cares for student and gives two extra chances if by chance you did badly in both midterms. I will recommend to sit on the first row and don't skip class. Will miss this class.

Hard to describe Dr. Z in a few words here. BEST PROFESSOR EVER HAD. He is EXTREMELY HELPFUL, always punctual, available for office hours. AMAZING WEBSITE. Always post solution of quizzes and exams on the same day. He makes all topics extremely easy. Two extra chances with doing extra problems even if you do badly in both exams. I loved this class.

This was the first time Dr. Z taught this class, and it showed in that he didn't have the best examples the first time he went over something. He always went over whatever wasn't clear in the last lecture. Very strict on no phone usage and you have to show up to class. He's very accessible outside of the class with office hours and free tutoring.

He left our class due to an injury, but acted as my tutor over email. He is the BEST PROFESSOR EVER. He is so compassionate towards students and really cares about helping his students. Taking his class is an opportunity everyone must take. The chemistry department needs to learn from him and take notes. I love this guy to death.

He is a great professor. Cares a lot about his students and wants everyone to do well. He created opportunities to help students that didn't do well on the midterm exams so they could still get a good grade in the class. He also gives a ton of practice material and is always free to help! Best math professor at Rutgers.

He's a legend. The material is dry, but he gets you to pay attention: He's a funny guy and gives you money if you correct him on mistakes. Exams are weighted heavily but they are very fair/easy and he even lets you retake them if you do poorly. While attendance is mandatory and he gives a lot of quizzes, you are still in good hands if you take him.

Dr. Z is a great guy, who is very straightforward, funny, and fair. His exams are fair and he does not try to trick you. Practice attendance quizzes and real quizzes (Definitely study for the real quizzes or they can come back to bite you) Homework was difficult compared to the exams, but gave a great conceptual understanding of the material, GOAT

Great professor, who really connects with everyone on a personal level. He also gives out little tokens of money if you correct his mistakes and do well on the tests. Very sweet and appreciative. He tries to remember everyone's name and shouts in class (not in a rude way, but rather playfully), which is really funny and keeps the class active!

Dr. Z is one of the BEST profs at Rutgers. He rlly cared about students' learning experience and made the classroom enjoyable. He made lin opt an easy to understand class, exams were like the hw and quizzes, and made class fun. Take him!!

Dr. Z is an excellent research advisor! He came up with many interesting projects for me to poke at, and was always helpful if I got stuck. We had weekly meetings where I would report on my progress, which gave me motivation to stay on task. Also he co-organizes the experimental math seminar, which I would highly recommend to all!

The best graduate class in the department. Maybe the best period! Lots of programming and reading required to keep up. Note that it's a real-deal graduate class. Most of the work is optional, but you get out what you put in. If you really do all the homework (and there is a monumental amount of it suggested), then you will be a real expert.

Dr. Z is my favorite professor in the math department. I took his experimental math class (which I also highly recommend!) before he was my advisor. He is the ideal advisor. He really cares about his students succeeding, is super accessible/makes time for students, gives great problems but also lets you choose your own, and is very supportive

Pretty fire prof and keeps you locked. Class itself is hard but nothing crazy.

The sweetest teacher (& he's funny). Everything was explained so clearly and he's really nice. Told him my name once and he remembered for the entire semester. Exams are pretty easy and he gives alot of quizzes, so you have several chances to increase your grade. Homework does get checked but for completion. Would highly recommend him!

Amazing professor who grades fairly. He also gives students chances to make up for poor performance on midterms. Actively interacts with his classroom, and he learns the names of as many students as he can.

Professor Z is engaging and cares about students. While lectures can be uneven, he's receptive to feedback and provides great support through office hours, tutoring, and a helpful class website. Using unstuck study and the free textbook can make this manageable course even easier.
