The data set quality seems a really spotty based on looking a few random problems (I looked at about a dozen in the "Physics" subcategory). Several problems had no clear question (or answer) and seemed to be clipped from some longer resource and thus had back references to Sections and Chapters that the models clearly couldn't follow. Worse is that the verification of the answer seems to be via an LLM and not all that reliable; I saw several where the answer was marked correct when it clearly wasn't and several that were correct but not in the precise form given as "the" answer and thus were labelled as incorrect.
