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.

I found the course a little tough, but it's worth the effort. It takes more time than mentioned. Apart from that, it is actually good and covers most of the topics required for interviews.

the last lecture was too fast. Would be good to divide this into two parts. Rest all is great stuff.

The course material was good and the understanding of the subject was satisfactory . :)
Thank You and keep us updated .

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).

The course material is good.
The assignments were not completely testing knowledge

A really great course, you should definitely take this second after Algorithmic Toolbox, as that has an easier learning curve for the very 'CS professor' style code (lots of single letter variables and other quirks) and how projects should be submitted and tested.
That said, there is a lot of good learning in this course. Make sure you have some good Algorithms textbooks to accompany the lectures, they have recommendations in the course. I personally use Sedgewick's book and CLRS which aren't exactly what they suggest, but work well. Take your time with the learning, make sure you really understand the concepts before moving on to the homework. Use multiple sources to learn (they provide plenty of links!) and you'll do well.
In response to a very politely asked request for clarity: I rated this 4/5 rather than 5/5 stars as I found that for my preferred language (Python) some of the starter files were very poorly created. This meant I often have to rewrite the initial parsing of the inputs because it would create variables that contained incorrect or incomplete input data. Further, there were some non-harmful quirks like semi-colons or parameters shadowing Python reserved words in the code. The next course in this series, Algorithms on Graphs, did not seem to have any of these issues, though!

Very good course. I would not say its for beginner. But would definitely helps you in the future progress of your career.

This course is very hard for non-STEM major student, even non CS-major student. Some concepts are very abstract to explain. The course team generally did a good job at explaining concept, but it would be better if they can offer more examples, animations, illustrations, sample code and explanations, etc. to help students understand these concepts. A rewarding course overall. Best if you are going to have a code interview.

Course materials are very smartly designed but some of the problems are too difficult for a beginner, though the solution could be very smart.

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.

Few more data structures can be included like Graphs .

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!

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.

Overall a good course. In my opinion the hash-tables and BSTs material was a little rushed.

The course is awesome anyways and focuses on more than just grades.

The lecturer Daniel Kane does not explain things clearly. I constantly had to switch to other material listed in references to understand what he was talking about. I know that usually lectures are supposed to give you only general understanding of the problem and you still have to read additional material, but with Daniel Kane it is practically useless to watch lectures. I am sorry if I offend him, but lectures were a real problem for me so I think I have to speak out.
Another issue with this course was poor design of home assignments. For example, after a huge Week 5 where we cover: search trees, binary search trees, AVL trees and all operations on these trees - there was no home assignment! Why? In consequent Week 6 we cover Splay trees and get 5 problems as home assignment. The first three problems have practically the same solution, you only need a few adjustments and these problems are on binary search tree properties (not AVL or any in particular). Then, there are remaining two problems that only cover Splay trees (as far as I understand). Such assignment design makes it hard to sort out the topic (at least for me). Moreover, the rest two problems are huge and as the result you cannot check only a fraction of your alogrithm instead you have to check it entirely. And since these problems are not necessary to complete it is really hard to motivate yourself to keep trying to submit them considering that it may take hours to find a bug in a huge (comparing to other assignments) chunk of code.
Overall, I find this course very useful, but comparing to Algorithm Toolbox the self-study section really suffered and two MAJOR topics were given to one not so good (in my opinion) lecturer. As the result I struggled not because of the course complexity, but because of inconviniences.
And also grading system acts strangely. In python3 graders don't usually accept recursion because of RecursionDepthLimit error, however, all stress tests on my computer were completed successfully, but I still had to rewrite everything in loops. I guess it is usefull to know how to implement an algorithm both in loops and recursion, but I'd prefer if they specified the appropriate method for the problem beforehand.
