I am going to speak as a broke student who has no money to get full access to the course or to pay for a verified certifications. I took advantage of the audit access to follow along the course and let me just say that it was really great and I've learned a lot of things. I'm also a lot more comfortable with the data structures covered in the course than how I used to be before I started the course. The course contains videos, lectures, slides, labs and questionnaires to help you understand things a lot better. However, it is unfortunate that the course doesn't give full access to all the assignments. In my opinion, a verified certificate is enough to push people to open their wallets and there was no need to lock coding assignments at the end of each lesson/module (which are crucial to helping people understand the concepts even more). But overall, this was a great course and I am grateful to the team behind it for making it available online. Thank you so much.

This course is fantastic!

I've previously attended Java and data structure bootcamps focused heavily on breaking down LeetCode problems and preparing for interviews. While these bootcamps taught me how to use various data structures to tackle specific problems, they didn't delve deeply into the underlying logic and design principles of these structures.

IN CONTRAST, this course has truly enlightened me about the "whys" behind data structures. It has clarified why Structure A differs from Structure B and the rationale behind their designs. This comprehensive approach has filled the gaps in my fundamental knowledge of data structures which I wasn't even fully aware existed.

Many thanks to Dr. Mary Hudachek-Buswell and all her TAs for such a thorough and insightful course!

I really enjoyed to the course. The videos were well-put together (clear, concise, informative), and the material lent itself really nicely to the format: video -> Visual Lab -> Quiz/Assignments.

As with lots of things in CS, I learned a lot by "doing", and I found the assignments very well-made and conducive to learning the data structures we learn. The instructions were straightforward and unambiguous - I knew what behaviour was expected for edge cases and others that popped to mind. Without being bogged down by issues such as "did I name the class right".

The labs aren't graded, but I found them super useful to understand the conceptual logic of the data structures. Which I found made coding much easier.

There is one caveat though. It seemed like all or almost all of the videos contained at least one "errata" or "Additional note". Those were clearly identified AFTER the video, but it did hurt my attention to the videos, since I would try to catch the erratas first so I don't pollute my notes with errors.

Not sure how complex it is, but I would have preferred the note to be overlayed in the video or something, so that I know exactly at what point there was an errata to catch.

Still, I give 5/5 because already while doing the course, I was using this new knowledge at work. Which, I found the knowledge to be more than the "Data structures", it's a new way of thinking about the data in computers.

Anyway, thanks for this course!
