Data structure and algorithms are undoubtedly the most important part of learning computer science. I like the material provided and I chose and I don't like the design of the assessments.
The Zybook contains two major parts, one is teaching some core concepts of coding by introducing python, and another is the academic part of different data structures and algorithms. They are both important and you will have to learn them sometime somewhere after all. Zybook is not a bad choice and they are detailed enough. I also used Pluralsight videos (Data Structures and Algorithms Part I & II) as my main learning materials.
The assessments are aligned with each other and not aligned with the book. I had a call with a CI and got some study tips including 2 mistakes in the pre-assessment questions. I think the pseudocode and Java multiple-choice questions are not efficient for our learning and test our ability in computer science, but in WGU just shut up and deal with it for a couple of hours and you'll be fine. The algorithms part is more reasonable, the Zybook and Pluralsight should cover all the things you need to know.
I spent 11 days on this course. These are knowledge that we will learn and review by ourselves throughout the career, so don't bother with it just figure out how to pass will be a smarter choice.
