What it measures

Molecular and cellular biology, genetics and physiology, at the undergraduate level. Questions are four-option multiple-choice, drawn from the MMLU test set's "biology" subcategory within the benchmark's "STEM" top-level group, and are graded on the single correct labelled option.

Task format

Four-option multiple-choice questions, graded on the single correct labelled option; commonly evaluated 5-shot, consistent with the rest of MMLU.
