I think the course content and assignments were great. A suggestion though, it will be more helpful if there are more and varied corner cases that would save time spent in thinking and making cases.

Data Structures was really interesting over all, also assignments are quite challenging. It's important to consult the external references & discussion forums if you want to get the best of it.

The last two weeks felt rushed. The Binary Search Tree/AVL Tree module doesn't have a quiz or an assignment and it's easy to move on without fully understanding both data structures. This allows for wasting time on the last assignment which relies on understanding AVL trees. I recommend reading the external resources for each lesson and making sure you have a grasp of the data structure before moving to the next module.

This is a great course which gives you the basic understanding required in handling data structures along with some state of the art techniques and applications for those structures. Had a little difficulty in following binary search trees because of the pace of the course and lacking detailed explanation at places. But overall it is a really good course to get up to speed on some of the most used Data Structures.

The course is overall really good. I learned a lot about data structures and got experience applying them for various problems. The majority of the lecturers were also good and they explained the topics in a clear and precise manner. However, the lecturer for week 5 and week 6 didn't explain the topics that he covered very clearly in my opinion. Overall I had a really good experience during the course.

Really good course. I learned a lot and enjoyed the instruction style as well as the way the exercises and assignments were graded.
I would've given the course 5 stars were it not for the final assignment which was made very difficult not so much by the content but by the code sample we were meant to extend... It was full of global state and mutation, very hard to follow and frustrating to work with.

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

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.

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).

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!

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.

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.

great course with challenging assignments, the problem with the course is the accent of some of the lecturers which make the lecture harder to follow also not enough examples in the lectures

In depth mathematical analysis and implementation of important Data Structures. This is a very good course for programmers looking to solve computational problems with first principles.

The course was interesting and challenging for me. The main problem that I had with this course was lack of communication with the teachers. But all the tasks and lectures were great!

Neil and daniel's teaching was great compared with the other two lecturers. I am saying this because they have a very low voice which made me lose interest during the class.
