The lectures and the reading material were great. The assignments are challenging and require thought before attempting. The forums were really useful when I got stuck with the assignments

Overall, it's good. But some chapters like the binary search tree and hash table, the instructions are now very heuristic. I can only understand the content after reading the textbook.

I have rated four stars for the course to be easily understandable for the basics, however it doesn't help much if you want to get into an advanced level, the instructors keep passing the advanced topics and cramming it after just giving a general idea.. In general, the course is good but the programming assignments are badly explained, if you get the explanation of the assignment it can be done

This is a very good course. The only thing I had problems with was the way the tests were set up - they were giving me no information about why my code was failing. I understand the reasoning behind not releasing test cases in failing tests, but like me - a lot of people keep submitting and failing, and in the end getting discouraged . Suggesting modification of test case outputs in the future.

I loved that I had a lot of really tough but relevant problems to code and solve. I only wish the presenters were more visual. With so many splitting, inserting, merging and deleting, I was hoping for some animation on the slides in the video rather than the presenters simply waving their hands. The books for supplemental reading were really helpful along with watching the videos. a few times

the content was pretty awesome, good point for you. I'm just willing the presenters will be more active with us dealing with more dynamic tools and not only keeping it up with the slides alone. I think it would be outstanding if we wrote code for the algorithm and implemented it with a few test cases as well. but overall it was really nice experience, thanks for your efforts.

It was a very useful and informative course. The sessions were taught in a concise but at the same time useful and practical way. In my opinion, the opportunity to solve the exercises is very limited for a person who can spend 3-4 times a week (2-3 hours each time) for the course, and the deadlines for solving the exercises and quizzes should be increased.

First weeks are awesome, it is a great course if you want understand very well some structures like heaps or union/find. I just think the last week is too fast and concise, I would like some additional work about trees and for many users could be a problem, otherwise will be a 5 stars without any doubt, though for me this course worked very well.

This course is challenging, and it is very informative. It would be great if it has smaller problems in which one can implement the data structures discussed in the lectures. In general the course is well explained, but the guy who explains about hash tables needs to provide further explanations or resources.

The quality of the course is very high. However I give a slightly lower rating than for the Class 1 from the specialization. The assignments seemed little unbalanced this time - some were very easy while other were very hard (I passed one after loading a special package to manipulate data or recursion limit).

Some of the exercise files were too time consuming to debug. In general, I would also prefer more rigour in the mathematics, but I am a maths student so probably have a less than common view on this matter. Overall though, this is a very good course, I found myself enjoying hashing and trees units the most.

All the data structures and algorithms involved in them were taught very well. I found the weeks involving AVL trees (particularly the rotation part) and splay trees kind of difficult to understand as the rotation for balancing the tree wasn't explained very well. Rest all was top notch.

While the learning material is excellent, on par on that of course 1, I think that coding assignments are really tough, maybe too much so. Even the very first assignment of every week, usually at warm-up level- has been very complicated. Something more gradual would have been nice.

The course is well structured and smooth. The content is rich and really covers the important stuff in data structures.
However, still, the problems come from the interface and the grading system, please Coursera you can do better than this in the discussion forum and the grader.

Another good course, though the last two weeks were a lot harder to follow than the prior ones. Not because the material was that much harder, but the lectures and homeworks were less clear (a lot of descriptions of how to do various operations without explaining why).

I liked the course overall. It helped me a lot, and I saw the positive effects in a short period of time. But please change the hashmap course with something else. It was pain to watch since the instructor just read some theoretical stuff from the slides. Thanks.

This course is very good for those who are trying to learn Data structure. well you have to have some basic knowledge of the programming languages like python, c++, java for the programming assignments.
Very good course for intermediate level. Thank you so much!

First I want to mention I didn't waste my time with this course.
This course help me a lot to clear my doubts and also learned modern applications, concept of DS in various fields as well throughout this course.
I appreciate help from Mentors and Coursera too.

It is a very useful course .
I had some problems with implementing the concepts as codes , I think the assignments have to be more easy to code without losing the main idea of them.
I am so happy and thankful for every teacher , they were all amazing :)

First 3 weeks were great (as in first course of specialization), but material in last two weeks was very hard to understand. Feels some mess in explanations compared to other part of the course. Maybe its because of difficulty of the last weeks topics.

Generally good, Russian lectures's pseudo-code is kind of giving me a hard time, guess I'm just not used to that style of notation, content of week 6 rises a bit steep, people might have hard time keeping up. Problem set was good though.

It's very fun to learn, and the explanations are very clear. But there are some parts that the explanations are still not very clear and I had to rewatch it multiple times to understand it. But overall, the course is very good!

this course has some good video explanations on every topic and such relevant assignments which can be applied easily. but for me some what hard because I haven't tuck another course they subjected before this one.

Binary search trees were not explained very well. Programming assignments are usually very easy. Nevertheless, it is a very interesting course and the assignment do help to learn about the topics covered. Useful.

Even though I am already aware of all these data structures, I gained some more in-depth knowledge about them, also got introduced to splay trees. definitely worth a try,some of the assignments are really good.

Thanks for the course. Content is good and videos are very well done. Only problem is that the assignment problems were gruelling and unfortunately it is hard to get one-to-one contact for help if you get stuck

The course is overall quite challenging. The explanations certainly could have been better with a little increase in diagramming stuff out. I had to refer multiple resources to fully understand the concepts.
