I did the test for a story I sold,
came out a 12. But a lot of the questions are genre related, as an example I consciously wrote the character as a shadow of my self, and not enough of the questions keyed in on the genre, to reflect the bias. As to good or bad I have always heard that you should write what you know, good suspension of disbelief comes from a believable character that extends it's existence in to an interesting situation.
In my case the plot revolves around a mildly disabled vet, and his reaction to a huge life changing event. Literally (pun intended) his whole world changes when his town is shifted 367 years into the past and onto a different continent.
Stories need to be interesting, and I think the test is trying to sort out the protagontist that always has too easy a time with it's problems.
If you are interested about half the story is available for free here,
