Challenging questions usually arise from the required problem-solving involved, rather than the level of content knowledge. An ideal question is one that nearly every participant would understand the solution of, even though they may not have seen how to solve it in the first instance.

These lists aim to offer all potential participants a feel for the level of mathematical knowledge expected, and hence help them make a reasoned decision on their suitability in becoming a participant.
