Really great! Clear, concise, rich and stimulating, filled with many examples. Only the last part on q-world, although extremely interesting and very well introduced, is left almost without practical applications :-).

The course starts with basic enumerative combinatorics like counting sequences, permutation, etc. and gradually moves into generating function, which is a very powerful tool in combinatorics. It also gives interesting combinatorial proofs of several classical results. The quiz is helpful and final assignment a bit challenging and definitely fun!

The professor is a little slow when he speaks but apart from that, he is a brilliant teacher. The course lets you get to the very roots of the topic by pushing you to do the derivations etc. Brilliant course!

brilliant

Есть баги в тестах (неделья 6 задача 4)

Nice work!

Funny

Very good presentation

Excellent selection of material and presentation; TAs were of great help as well. The techniques taught in this course will be a nice addition to my algorithms analysis toolbox.

by far the best math course I had (and I've taken many) on coursera

I enjoyed the course.

The lecturer was very good and the material quite interesting.

I feel that the assignments where sometimes very different compared to the material covered but I ended up doing extra research and learning more which is good!

Many thanks to the Coursera Staff as well as the Higher School of Economics.

Great lectures and content. I really enjoyed it. However, the solutions exercises could be clearer and in more detail. Thank you!

The content is really interesting. but the presentation could be improved.

but thanks for such content

The Quality of this Course is very bad! The Person who created this course is not involved anymore! There are "Mentors" to support the Course. They dont even know how to write in latex. No Solution, no transcripts! Compared with Modern Combinatorics this one star max!

Excelente course with real university level of concepts and exercises!

Great course!

Great course

This was an engaging course and I welcomed the opportunity to try something a bit more advanced than the typical offerings on Coursera. Lectures are very well presented. Homework assignments were pretty good and the online forum was helpful. I recommend this course and I would be interested in further courses like this one. I found it helpful to have a couple of textbooks on hand for reference. For the earlier material I used Shaum's Outline of Combinatorics by Balakrishnan (free download on archive.org) and for the material on q-series I referred to Theory of Partitions by George Andrews.

Suggested improvements: add student interaction during lectures to test understanding and supplement with worked problems in videos. Also add lots more problems for students to work on.

(I have found that with nearly all online courses the number of problems provided is too few for me to learn a topic).

Very mathematical, but cool and well done!

This course is great! The instructor exposition is very clear and simple. Recommend to anyone considering this topic!

Very good gourse, I persoally enjoyed the lectures in which the relatipnship with other areas of mathematics were discussed.

This is a wonderful course. The lectures are engaging, clear, and intuitive, but from my perspective the best thing about this course is the depth of the problem sets; although not long (usually 3 - 4 problems), each problem requires genuine thought, understanding , and creativity. This has been especially refreshing in the world of online courses, where shallow and computational problem sets can sometimes be the norm. I highly recommend this course to anyone interested in an introduction to this beautiful subject.

Excellent course. I hope there are more courses by the same team.

Marvellous online course. High level and ultimate lessons.

Don't underestimate the level.

Good content, but way too slow. Please use pdf instead of writing everything.
