The course was engaging and comprehensive yet a lot of the topics mentioned, especially in the last week, were not explained at all - for example, Big O Notation and time complexity. Moreover, there was an immense disparity between the difficulty in the problems that were to be solved as coursework and the bonus track.

Interesting ideas. Not always well explained. My biggest question, though, is what exactly did I learn? A bunch of abstract mathematical concepts without anything really tying them togeher. I get how it's discrete mathematics, but that's because I know discrete math outside of this course.

It's hard to cope up with someone who didn't study math in the past. Course content is not sufficient according to the problem sets. I had to look for references to the video and then would understand everything completely. Honestly, I wouldn't recommend it for a non-math person

The course material is great! Also the way the course was planned is commendable. The course instructors especially Prof Alexander Shen are hard to understand most of the times when they explain a certain concept. The explanations by instructors need to improve.

It's a very stimulating course, though not caring for students much. The material sometimes should elaborate more on concepts, say in week 6, it should've been clearer to student what are permutations in a clearer sense.

The course material is great but they should improve the explanations and practice what they go to say before film the lessons. Making too many mistakes while explaining math concepts ends up confusing the students.

It certainly was an intriguing course, and there were good puzzles which I have liked. However, I felt a little disappointed because the class ended so abruptly, and I am not sure how much new math I have learned.

Очень уважаю Александра Шень, учился по его учебнику, очень нравится его манера преподносить материал. Однако очень разочаровали остальные лекторы. (Уровень английского, материал и манера преподавания)

The lectures were really good, however explanation of more exercises would be a bit helpful as the videos are fairly short, I had problem understanding some of them due to limited number of examples.

the strategy of "try first" is great tool and is a must in my opinion to learn math, I hope Coursera improve more the quality of the lectures, add more exercises , Overall thank you so much

The material was interesting however the instructor Alexander Chen was incomprehensible. He was unable to verbalize a thought or explanation without sounding nonsensical.

I wish it went a bit more in-depth. I also wish there were more examples to practice. Overall, however, it was a good course, I have learned a lot.

There are no videos from Week 4. Most quizzes are given before explanations. So I solved many quizzes without knowing the intent of the questions.

totally it was a good and beneficial course but the heavy foreign accents of lectureres made it a little difficult to follow the lectures.

It's really very interesting course. I hope you all enjoy this course.

logical and interesting subject.

The course was very basic for me when I compared the material with the book of Discrete Mathematics

Last week was a bit confusing because the concept of permutation and cycles are mixed I guess.

The lectures aren't good and the assignments are not well explained as to what we need to do.

I didn't really get the lessons. The instructors weren't confident in teaching their topics.

The quiz were all very interesting, but sometimes it was hard to understand the lecturers...

the honors selection

is buggy but you can still complete

the course with honors, sadly.

Good course with many interesting quizzes although it is lacking of clear explanation

Shallow content, I was expecting more reading and depth in most of the concepts

Last 3 weeks were not engaging at all, the first 3 were amazing (my opinion)

Explanations of Puzzles are not always clear.

Week 6 is very complex.
