Materials in this course 'Unordered Data Structures' is not as clearly explained as its predecessors: 'Ordered Data Structure' and 'Object-Oriented Data Structures in C++'.

That's why I only gave 4 stars. I just tell the organizer my wish that it could be as perfect as the other two :)

However, in general, it's a good course which has well-organized material and well-prepared homework.

Everything is ok for an accelerated course but assignments are though to understand - you write a few lines of code but when you try to understand the rest it feels overcomplicated. I think graph search tasks would be more valueable to implement something simpler but almost from scratch. Previous course of specialization was better in my opinion.

a little bit too fast-paced when teaching about graphs. It is a complicated alogorithm to talk about. Yet, I noticed a lot of material has been edited out from the original content to fit the subject in one week...Otherwise, I like this course. It is very informative.The quizes and projects helped me understand the material better.

Really good and succinct course to gain a foundational understanding of data structures & algorithms. I would have liked some more challenging assignments, as I could complete some of them without writing more than 20 lines of code.

A lot of new concepts learned. However I would have like to do more programming, exploring more features of C++. Changing only one or two lines of an existing code does not help much in our learning.

Great course! Very interesting lecture material / content. I can't give this course a five however, as the assignments seem unnecessarily convoluted, and abstracted to demonstrate the material.

Could have been a bit more explanatory for people not from CS background. Typos and mistakes should have been eliminated to the largest possible extent. Leaving these aside, nice course.

Overall, great course. Slightly obscure challenges sometimes, but homeworks were awesome because of how well commented all the provided code was.

Instructor and videos were also amazing!

Good class. I'm still a little mixed on the approach where the student just supplies a small amount of code in a large (mostly complete) class. Nevertheless, enjoyed.

Overall very good course. It is VERY time consuming if don't have background in CS. Each programming projects can easily take 35-40 hours to complete.

The final course of this specialization, really useful, and I learned a lot. Just need more practices to understand some difficult concept.

The last section on graphs seems hurried, everything right up to BFS seemed structured but it felt like there was a sudden pack up.

I wish the course was more detailed. Some PDFs to explain the concept more. Other than that I am happy with the content.

overall course was excellent but there were a few mistakes in week 4, which took a bit of extra time to understand.

Hard topics nicely explained. Wish the lectures cover more content. The assignments were a bit too straightforward.

This course is good though some of the contents may need refinement. Code examples are very helpful.

The class videos and the quizzes are excellent. the coding part is a bit to easy

Very Nice Course, recommended for every Computer student.

I've audited this course. It was useful for me. Thanks.

The course added alot of knowledge to me

Needs to be a bit more in detail

Tough, but I am glad I took it.

Still not enough assignments.

Nicee course.

I've finished all three courses in this specialization. They are all great overall. However while studying the third course I feel like it's not well organized as the first two courses. There are some errors in the video that are not corrected yet, with only a few pages of note inserted into the video. And I think the most important part in this course is the run time analysis. But somehow the professor just went through them very quick with only a few words of explanations. I have to check back the old slides and the forums to read the explanations provided by the assistants. It gave me an impression that the professor just want to finish each topic as fast as he can.
