I was given a lot of such tests during my school time (during the equivalent of american middle school six to eight a year, during the equivalent of high school four a year). The range they measured usually was between 172 and 196, especially strong rating in logical abilities and rather weak in three dimensional imagination. It is to mention that I always spent a lot of time learning and reading and therefore always was ahead of most others in my age group what might have distorted the results. I don't consider them objective at all because even if such tests are meant to be mostly neutral to factors like age and education do these factors still play a big role, especially while growing up.
I didn't do a single test in the past eight years (since I finished school), so I can't tell you what I might have scored as "adult". I also don't intend to do so.
Practically talking, I sometimes have strong problems with social interactions that might partially result from the fact that I tend to skip simple logical steps in conversations, so I don't consider that something great at all. People having conversations in german or finnish with me often complain about me jumping from one thing to the other, even if (at least to me) they're logically connected. Writing/talking in foreign languages I haven't mastered (english, french, italian, russian) helps a lot there as it slows me down.
I borrowed a pencil from a transfer student on 3rd of May 2001. It was her last day and she left before I could return it and I didn't had any contact with her since then. However, I took it home and placed it besides my monitor. The desk and monitor have changed for several times over the years, the pencil however is still lying there waiting for its pickup. I accidentally dropped it on the night from 24th to 25th June 2009; since then I do hope that it's not broken inside. (I am aware that makes me a weird person).
