115 is about "average" on the test. It's a self-administered test, kind of like those you get in magazines, all the answers are "yours" so can change with your mood, etc. I think pretty much everyone shows something that could be identified as a borderline trait every now and then, I'd look into it if it bothers you or work on those particular behaviors you did not like, etc. That's all the test is for, entertainment and as a guide to see if you come up with a degree of something that startles you or that you didn't realize was there, etc.
