An excellent survey of LinkedLists, Stacks, Queues, and Trees. The homework and quizzes are rigorous but don't attempt to trick or mislead the student. While much of the homework code is already written for you, the important parts are left for the student to implement. Highly recommended.

It was a great course to learn about various ordered data structures. With this you get a basic understanding about them, and about their implementation details. Its Programming Assignments were a little tough and challenging as well. I really enjoyed taking this course.

Excellent course.

The tests are stellar - they really make you think. They are not hard, you just need to be really careful and pay attention to every single detail.

Prof Wade Fagen-Ulmschneider has a way of explaining things that really sticks.

Especially after looking into other, similar coursera and/or online courses, I have to say that the course quality and teaching quality of this course and the other two courses, is by far the best. Thanks, it was a lot of fun & I learned a lot!

The weekly projects are the most challenging but a lot of the code has been built by the professor. I fear i may not be learning how to code but instead just writing if else conditions in functions. I hope that is not the case in the real world

Great coverage for an intro to data structures such as arrays, linked lists, binary trees, heaps, etc. It has a nice balance of quizzes and coding assignments. It isn't rigorous mathematically but provides a good intuitive understanding.

Practical and informative. The topics were presented in a way that made it clear the advantages and disadvantages of each data structure. The instructor did a good job of explaining the properties of trees, heaps, and linked lists.

Instructor provides very clear explanations of the topics. Even though pace is relatively fast, it is not difficult to understand things. In addition, staff monitors forums, and responds to posts very actively. Highly recommended.

Thoroughly enjoyable course. The exercises were thoughtful and stimulating but not overly tough. Prof. Fagen is an exceptional instructor presenting the material in a clear manner. You can really feel how much he enjoys teaching.

This course covers indeed a lot of new material for those not introduced previously to it, but also if you pay enough attention and work on the assignments you will get a lot important knowledge about the topics covered.

Excelent Course! The lectures were very well driven and all challenges were not really hard but ok. Only thing is that the instructor keeps calling algorithms to the data structures haha! Either way, 100% recommended!

Really liked the course. The way instructor helped in understanding the basic concepts of all the ordered data structures and algorithms. Really made sense. Also, the quiz and assignments were helpful too. Big thanks.

The difficulty level and the exercises of the course is very good so that the learner can get a working knowledge of such ordered datastructures. This course is really helpful and needed for students of all levels.

I think the topics are well explained, but you need to know about these structures beforehand. The projects are asked in a way that you need to understand the concept and how to implement it to make the projects.

It's not recommended for beginners. However, I highly suggest those who have learned C++ participate in this course. The assignments are well-designed and challenging. I'm glad to have a chance to join this class.

This course was very interesting and a lot of fun. I loved learning about what goes on behind the scenes in some of the widely used data structures. The introduction to run-time analysis is also very approachable

This course challenged me, and I had to really grind on some of the problems; however, I feel I'm really expanding my CS knowledge with every new lesson. Enjoying it, and looking forward to the final section.

Fun informative course that provided a solid introduction to B-Trees, AVL Trees and Heaps. The videos were well done and covered the common algorithms associated with Trees such as level order traversal.

Outstanding class. I really learned a lot. I had previously had some difficulty wrapping my head around trees and recursion but this class made the lightbulb go off. Thank you!

My favorite Coursera specialization! Responsive staff, lectures are very clear, assignments are both challenging and educational (closely related to lecture materials). Thank you!

Was a bit fast for me to catch at first, but I eventually got the hang of the pace. Loved the resources the instructor provided. Illinois is lucky to have such a great educator.

Had to do the quizzes before realizing how much was went through in the short video lectures! Very compact and useful course in showing various data structures.

This is one of the best courses I have studied so far, the instructor's way is very easy to understand yet provides in-depth understanding of the material.

Excellent course, excellent teacher. Just the right approach to teaching data structures, Ive seen a few videos in the topic and this course is very good.

Well-taught course! I love the instructor's enthusiasm and great explanations. The exercises are diverse and really help you reinforce your understanding.
