Practice! Practice! Practice!

These are the 3 secrets that changed my career graph. I came across The site offers practice through mock tests on 1Z0-820 upgrade to oracle solaris 11 system administrator. I was a regular at the site. First i took demo test and then the premium membership. I am a fan of this site. I still visit the site to clear my concepts through practice tests. I got 80% at my first attempt.
