I believe toward the end of filling out the CSS Profile, the questions for individual schools appeared (Section called SQ for Supplemental Questions). It looked just like any other question. I think one was about how many and what kind of cars I had. It was a few years ago. My kid ended up going to a school that did not ask any additional questions, so I only saw it the year he was applying to schools. There was a way to figure out what school requested what additional question.
