How they differ
Both decks cover essentially the same Step 1 concepts — heavy overlap is the norm. The differences that actually matter:
- Depth & volume. Soze Step 1 is light / single-pass (~5 cards/concept, ~3,500 cards); Lightyear is moderate (~16 cards/concept, ~14k cards). More cards per concept means harder drilling on each point; fewer means a faster single pass.
- Lightyear covers more fully: Public Health Sciences, Respiratory.
Coverage differences are reported at the area level — our card-to-concept mapping is reliable in aggregate but not precise enough to name individual missing topics.
