Not commenting about the difficulty, but some of the later questions definitely require a bit more specialised knowledge. #74-77, "uniform, dense, smooth map, open set". Basically some topology questions. Some other questions are just weird, #54- just plot a parametric equation? Also a few integrals?
I think anyone (kids included) could go pick up this stuff fine, but doesn't quite match with the blurb given (why not define some of these things in the questions and work through it that way).
I imagine then what this could be good for is if you use these questions as a bit of a teaching guide/goal. Maybe work your way through the concepts/problem with the end goal being the question, but then introducing stuff as necessary, rather than just throwing the entire question out there.
