I think you did Kriston. MY son took the 3rd grade ITBS along w/ his HSing buddy. We compared test scores. On some sections (the language arts) you miss one, you're at 99th%, you miss two, you're at 93rd% (not exact numbers but it was dropping about 4-6% points per question wrong). But in the more critical thinking sections (the ones that can be used for JHU-CTY for instance) such as science, you miss one 99th%, you miss two 98th% - so those sections allowed you to get more wrong and still have a percentile ranking.
I thought it odd that the average percentile ranking was 41-89%. Above avg was 90-99%.
Ok I just checked. Miss 1 on science and it was 99th but miss 1 on vocabulary and it's 96th% and miss 2 on social studies and it's 96th%.
