Well I got 15 on the test, and I do have ADD. I'm 19 now got diagnosed about 6 months ago with it, although that was when I was 18, so I had to see someone who deals with the 18 and under crowd. Sometime in the next 6 months I'm supposed to go see an adult specialist for a new diagnosis, because apparently there's a huge difference between adult ADD and the stuff found in kids. By the way, that test was like one out of about seven or eight tests I had to do, so I wouldn't exactly consider it a reliable source.
