I imagine quite small, if any were allowed to. Tests like these usually also have a hidden rubric such that the test taker never quite manages to reach the minimum passing grade. It's unlikely anybody with the education of a high-schooler (even a fairly advanced one) would be able to solve very many of these problems in a typical allotment of time for a test. They're not sophisticated problems, in the sense that relatively basic mathematical principles can be used to solve most (or all) of them, but they're really quite complicated problems for a test. I mean "complicated" in the sense that they require a fair bit of rather tedious busy work to arrive at a solution.
