Okay... there are errors galore, but it's still the best resource to pass!

Like the other reviewers said, there are errors here. It's not too big of a deal if you know what you're doing. The git folder can be found in the course questions on testbanks.wiley.com under RESOURCES. It wasn't easy to find, but it does exist.
I passed the Cloud Practitioner, Solutions Architect Associate, and SysOps Associate tests with ease, but didn't pass the Developer test (not required with SysOps passed, but I'm taking all of the tests.
For my Developer Associate studies, I started out with A Cloud Guru, Cloud Academy, and Linux Academy resources, watched the videos, and took every practice test I can find.
This book covers the material that was on the exam - that's all I'll say. I have yet to take it again, but everything that was covered in detail in the questions I missed is here. The third-party training is not sufficient without a lot of supplemental study in anything you don't use religiously on your own.
Finally, the test questions here are decent because they mirror the Amazon certification goals nicely. Taking exam sims you find on the web will just give you false confidence, although I hear that the Stephane Maarek ones on Udemy are good. I *highly recommend* highlighting anything you don't know, and making your own questions using test software. This is the best strategy, because you need to retain knowledge, not just memorize poorly-written questions that will ruin you for the exam.

AWS changes the exams so much, I don't know how long this will be true. I recommend digesting this book and taking the exam as soon as possible. The Advanced Networking book is several years old, and while it helps, it seems like the best way to handle AWS content is to use the newest study materials, and stay ahead of the changes.
