After going through the linxacademy.com course, I looked it over again. The book is very good. It actually touches on material deeper than what is provided on linux academy. I don't think the book is well suited for folks who are beginning Linux. The only reason I say this is because although the material maybe have been presented, I think someone may glaze over important information/material. A good, free website or study site would be https://www.certdepot.net/rhel7-rhcsa-ex200/ They have a question of the day. Every time you go to a link on their page, you'll see a new EX200 question. That's another tool that you can measure where you are at. I would say those questions are similar to the format of questions you'll see on the test. But, yes, if you did a lot of labs on a CentOS environment, then you should be good to go with Mike Jang's book. I really hope and wish you pass on your first attempt. If you have any questions that won't break the NDA, please let me know. Again, best of luck.
