SolidGeo-Bench: A Pilot Study on Category-Level LLM Performance in Chinese High School Solid Geometry

Large language models (LLMs) are increasingly used in K-12 mathematics education, yet little is known about how their performance in solid geometry — a domain requiring spatial visualisation, cross-section reasoning and multi-step proof — varies across problem types. We present SolidGeo-Bench, a pilot set of 95 Chinese...
