I'm looking into getting my RHCSA certification, however I would like to get RHEL to practice on. I googled it and it looks like what your paying for when you buy RHEL is support. is there any way to get the software without the obvious torrenting?
Install CentOS or fedora. Both are Red Hat. CentOS would be the recommended install, its RedHat provided for free with no support. Fedora is Red Hats beta testing distro which is up to version 14 or something like that.

CentOS stays on the same versioning as Red Hat which it releases as "stable". Fedora is usually ok but it does have more bug/security fixes and issues as it is a beta testing solution. I wouldn't recommend Fedora for an enterprise solution but for learning it would be great. However, if you are looking to take the RHCSA/E use CentOS so you don't end up spending time learning syntax or using features that are not available in the current versions of RedHat which you will be tested on.
Basically, unless I told you so you would not notice the difference from a RHEL 6.1 Server and a CentOS 6.1 server.
Red Hat is based on Fedora, starting from a non-current version (so that the software has been thoroughly tested by everyday use) — RHEL 6 is based on Fedora 13, I believe — and only keeping the programs they think their client's will require.
CentOS is based on Red Hat, compiling the source code for their free software and finding replacements for anything else. CentOS will give you a probably 99% RHEL experience, and you can add extra software for all those tasks that Red Hat don't provide for by using the EPEL and RPMfusion repositories (see the CentOS advice on doing that). As you can see, I use it — not because I'm a computer professional, but because I just like it.
While Fedora is an excellent distribution, I can't recommend using it to study for the Red Hat exams. While RHEL 6 is based in part on Fedora 13, some of it also comes from Fedora 12. I've found that the features in RHEL 6 are subtly different from both.
I think it would be disturbing to discover those differences in the middle of an exam.
As others have suggested, CentOS 6 (and Scientific Linux 6) are built from RHEL 6 source code. Those are better "free" options than Fedora.
Both distributions, which I call "rebuilds" are freely available as ISO downloads from their mirror sites. The only difference is that you won't see Red Hat trademarks in CentOS or Scientific Linux. The features and functionality of the tools that they build from Red Hat source code are --identical--.
