Your score is actually a comparison of how you did compared to other people who took the test in the same time period. By definition, 60% got a 5 or lower, 17% got a 6, and 23% got a 7 or better. Like Scotty said, the best thing to do is submit an application.
This forum gets these type of posts every few days, so people don't always respond to them. I would suggest searching old posts, but remember that things change quickly. The situation when I was selected in 04 is different than today.
