Ohh yeah, I did that Duke thing in 7th grade too. It doesn't count towards college or even high school at all. If you score high enough (I'm not sure about the ACT, but on the SAT if you got 1200 or above) then you were invited to a recognition ceremony. It really doesn't do a thing for your transcript, but schools and colleges will send promotional material (Boarding schools mostly and colleges like Duke, Vanderbilt, A&M,etc). It's too bad you didn't score as high as your friends, but this was an optional test. I know that the math section is almost impossible, but you'll do much better once you've actually learned it!
