You were just curious, and curiosity is your right. Unfortunately, it isn't always terribly welcome with some people.
The bottom line is no one on this forum will answer your question about the score. We either don't know, or those few that may know are not likely to answer.
Don't worry about or apologize for having asked your question- that's what forums are for. You will however discover, by performing a quick search, that the question has been asked many times for different trades. There is never a simple numerical value provided in response to these queries.
Like everyone else is saying (or should be saying) just do your best, prepare using the materials and advice provided to you, and you'll find out whether or not you qualify once you've written the test.
Best of luck!
