You first have to consider your background.  Are you a system adminisrator? Helpdesk tech?  Programmer?  End user? All of these questions have to be answered by you first.  The course will impress upon you some legalities, tons of tools (courseware for version 6 has around 4000 pages of material), and if you have a good instructor, some real world examples of how the tools are applied. 

You need to be familiar with Linux, Windows, and preferably OS X, as well as any other system you can get your hands on.  At an absolute minimum, I recommend knowing Windows well, both from a user and an administrative stance, and learn linux using a virtual machine.

There are requirements for taking the exam and the course itself.  Follow the links in H4TT1fn4TT's post. 

Version 7 has just been released, and the reviews are limited right now.  Wait a couple of months, get some real world admin/helpdesk experience, and then look into the certification.  The more experience you bring to the table, the more you will get from the course, and eventually the certification.  Good luck in which ever you choose!

I can not visit the link you pasted into your post. The website is untrusted according to Firefox. But I will keep in mind what you said. I am not certified penetration tester in any way so I am glad I learned something new as well. All I can give as advise to people is what I find myself using google on these kind of subjects.
