Don't mean that in an arrogant way but just looked at the RHCSA the first time and wonder if it's really pretty easy or if I'm totally underestimating it.

I never worked as a professional admin and I'm not an IT professional in general. I'm using Linux for a couple of years and I'd consider myself what some call a 'power-user' I guess.

I like to play around with my system and I often read up some stuff, different tutorials, wikipedia articles, I have a small VPS for my blog and I read the 'Command Line and Shell Scripting Bible' when I was new to Linux.

I always thought that RHCSA was something pretty tough to pass but looked it up today after I read the "Passed my RHCSA" thread here.

To be honest I'm under the impression that a somewhat ambitious Linux user who dealt with a private server and set up some VMs plus knows the basics of Linux already should be very familiar with 90% of the topics.

LVM and SELinux come to mind as two things people maybe don't use on their desktops. But apart from that most topics seem to be pretty common, as in "everyday life stuff" not only professional Linux administrators.

So is could I be right or do I definitely underestimate the RHCSA testing? Is there some additional difficulty added by very strict testing or time pressure?
