Quality axes are shapes, not exact figures — the card-to-concept mapping is probabilistic. Depth is study style (cards per concept), not a quality score. How we audit decks →

How they differ

Both decks cover essentially the same Step 1 concepts — heavy overlap is the norm. The differences that actually matter:

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.

Which fits you

Pick Soze Step 1 if you want fast high-yield pass / supplement; pick Lightyear if you want comprehensive, curated. Either way, the only thing that moves your score is what you've actually reviewed — not which deck ships a few more cards. Full Soze Step 1 audit · Full Lightyear audit

Frequently asked questions

Is Soze Step 1 or Lightyear better for Step 1?

Neither is strictly better — they overlap heavily because both cover the same Step 1 content. Soze Step 1 is fast high-yield pass / supplement; Lightyear is comprehensive, curated. The practical difference is depth and volume — how many cards each spends per concept — not which concepts are covered. Pick the one that fits how you study.

Can I use Soze Step 1 and Lightyear together?

You can, but because they overlap so heavily, running both is mostly redundant — you'd review the same concepts twice. Most students pick one as their primary deck. The reason to choose one over the other is its depth, volume, and style, not chasing missing content.

Whichever you pick — see what you've actually retained, not just what the deck covers.
