I have a class/test next month for RHEL 7 RHCSA. Any study guides available for beginners and up to snuff by 3rd week of Feb?

I have the opportunity to have a 5 day class and a test for RHEL 7 RHCSA. I am very exited and eager to learn/cram this all into my brain before class starts in February. I know very little Linux right now but can/will learn fast. Any advice? Thank you very much ahead of time!
