I am a sophomore in high school and I managed to pull a score of 140 on this test. I took an "official" iq test when I was 9, and I scored substantially lower, which led me to question the validity of the test. However, some reviewers have said that the questions are not very far off from those on an official iq test (I dont really remember the official test I took), so I suppose it wouldnt be so much of a stretch if had matured that much intellectually.
