Practicing most of the tests twice

As the VCS-278 preparation questions on this site come with the option of unlimited access, i made a point to give every test twice so that i know thoroughly where i was winning and lacking. All this helped me understand the Administration of Veritas NetBackup 8.1.2 certification exam syllabus in a proper manner. They gave me points to ponder upon and get an edge over others in the tough competition.
