I got 17, but I don't see how the test can be too accurate with only true or false options. I think it should be on a 1-7 or 1-9 scale. Some of them that I checked are only moderately true and some are very strongly true. Then there are some that I didn't check that are true at some times or to a mild degree.
Also, I got an 8 on Ad hoc's sensation seeking test. I don't like doing that sort of stuff because of the danger and inherent nervousness that entails it. I prefer to be in a familiar place most of the time, but I do enjoy the feeling of exploration, I just keep it to videogames. I think I am mostly normal in that regard.
