Authoritative Calibration Dataset
Curriculum Specification & Exact-Match Catalog
Every drill session selects deterministically from this verified chemistry dataset. Prompts dynamically alternate between symbol-to-name and name-to-symbol recall, evaluating written submissions via character-for-character exact matching.
