Step 1 Anki Deck Audits
Independent coverage analysis of 5 popular Step 1 Anki decks, mapped against Lacunos's 915-subtopic Step 1 content outline.
Our outline and high-yield designations are calibrated against the canonical Step 1 sources — First Aid, UWorld, Pathoma, Boards & Beyond, AMBOSS HY badges, and community deck tags. Methodology →

| Mnemosyne | Comprehensive | Comprehensive | Moderate ~16 cards/concept | ~15k | Broad coverage, mid-volume |

High-yield core = how fully the deck covers the must-know concepts. Breadth = how much of the full outline it spans. Depth = how many cards it spends per concept (study style — deep drilling vs. a fast single pass), not a quality score. Step 1 cards counts cards whose content maps to our outline (off-exam cards excluded); figures are rounded estimates. How we audit decks →
