I find it...odd (maybe I'm showing my age...) that there's no trianing books to buy for something like the System Admin for Red Hat exam. Are there even PDF books? The lack of training material for these exams is a bit disheartening. I get the Learning Subscription is being pushed...but If you're not subscribed, it's like zero ability to progress by yourself..
I'm pretty much a noob myself but Sander Van Vugt has print books - study guides for RHCSA. You can check out the O'Rielly website or just Amazon.
And someone also recommended to me a book by Asghar Ghori. You may want to check that out as well.
Nothing can beat having a nice book with you
The red hat training is very expensive... These alternatives might be more cost effective.
