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.

Clear presentation of basic data structures with non-trivial applications. Material is presented very well for beginning coding or as a review. Online grading is better than many programming courses. Works well as a stand alone course.

It is a really professional and enrich course ,, materials are very helpful and assignments really help me to improve and check my understanding.

I think this is one of the best courses out there in terms of the rigour as well as the quality of the content. The instructors take great care to actually explain how the data structures work internally, complete with mathematical proofs wherever necessary. The assignments are also very good and help to solidify the understanding of the concepts.

It is a great course. But it would save a lot of time, if we could actually see errors of our submissions. Checking if your algorithm is working correctly (output wise), when you actually have a stack overflow on some test is very frustrating.

the problem is very good,the teacher has a good teaching.

this is my second course that I have taken. I learned many things this course is more difficult than algorithmic toolbox but when you work hard you can finish all units
in the beginning i thought that i would not be able to continue because i dont have a lot of knowledge in c+, java or python, but i decided to learn c+ sonce the first course. these coursed were very difficult but i could finish then and this is all because of the professors whom were excellent and the challenging homework.
Thanks to everyone that has dedicated there time and resources to mke this wonderful course, I appreciate it a lot

Great course with great content. Really enjoy the addition of support material and test cases for the difficult problems.

This is a great course. The lectures were easy to follow, CLRS references are also good to clarify anything that is not covered in the videos. Programming assignments are challenging enough and spot-on to practice the concepts.

I found the assignments challenging in the absolute best sense of the term, and therefore incredibly rewarding as well! Whenever I've gotten stuck, the answer was always in the course material somewhere, even if I didn't see it there at first. The discussion forums were extremely helpful, and I was astounded to see that that instructors were still actively monitoring the discussion forums and responding to student questions. I'm obviously not an expert in this field, but I've been an educator before, and my own impression of the assignments was that they were extremely well designed: it was impossible to pass them without knowing what you were doing, the tools to approach them were always found in the lectures, and the challenge problems pushed your knowledge even farther. I would recommend the specialization to everyone. Additionally, I noticed that the content aligns well with other DS&A syllabi I have seen in brick-and-mortar institutions, especially the first 3 or 4 courses. It's also a very nice luxury to be able to submit in Python. I have certainly learned a great deal.

I liked this course alot.
If you are a student and come from the previous course, you may only read the cons, since this course has the same spirit as the previous.
1. The lectures contain quite a good material which is somehow difficult and they made me to pay attention. The lectures are based on dasgupta's book and MIT course book.
2. There are links to additional materials, I found the dijkstra's book and MIT course book, so I was able to gain extra information for topics which interested me.
Also slides are very useful
3. The forum! This course has a life forum where you can find help or share your ideas.
4. The teaching stuff! They are answering student questions and taking part in discussions
Having compared this course with the previous one from the set, this course suffers from luck of interesting problems. The previous course has more than ~25 problems and for each module it has advanced problems,even more they added extra problems during the course running.
This course has ~12 problems and only one advanced for the whole course!. Only this advanced problem made me take a piece of paper and a pen and draw trees, and play with toy examples. Only for this problem I wrote a stress test. That is the most fun for me of studying!
If this course didn't have this advanced problem, I would barely give it 3 stars.
Theaching stuff, please conider to add extra problems, the first course is awesome and it is way too good. This course is good, but it think you may develop it not only the first one. Otherwise students may get dissapointed if they come from the previous course.
I hoped that you would have added extra problems, so I slowed down, my expectation didnt come true :(

Thanks for the great course! Giving it a five stars. Although, the programming assignment for the last week could be better. Instead of implementing the same in-order tree-traversing three times with minor variations (first time as requested, second time to test if a given tree is a BST, and a "hard BST" variance), would be better to include tasks on implementing balancing and splaying a tree.

Similar to the first course in this Specialization, a great course on algorithms and their applications. Frustrating at times, but I definitely recommend this course (and the others) if you are serious about implementing algorithms for whatever purpose.

This course is well paced and covers all the data structures needed to code efficiently. This course also provides good real life problems in the form of assignments.

Recently the instructors updated the course and implemented a solution to all my past complains.
In my opinion the team is really taking the quality serious.
However I just want to mention, that there are regular session for each course so that everybody can avoid having two overlapping courses in this specialization at the same time.
I did not know that and worked on two courses at the same time, until the instructor informed me about the short interval between sessions of a given course.

Personally, this course is interesting and essential for the learner to proceed to other more advanced courses, either within this specialisation or not. There is only one suggestion that it will be better if the instructors can provide more details of the pseudo codes.
