This comes to not "smartness" of LLMs. But reality that we do not even want anything novel in these exercises or exams. And same areas are repeated multiple times so naturally there is lot of these in training data.

This is one area where LLMs really should excel at. And that doesn't really mean that students should not also learn it and be able to solve same issues. Which is real dilemma for the school system...
