Which NBME Step 1 forms does this calculator support?

NBME 25, 26, 27, 28, 29, 30, 31, UWSA 1, UWSA 2, and Free 120 — 10 forms in total. Retired forms (NBME 1–24) are not included because community regression data is no longer reliable for them.

How accurate is the Step 1 score prediction?

Predictions carry an estimated margin of ±5–10 points — standard for community regression models. Treat the result as a planning estimate, not a guarantee. Cross-reference with a second form before making scheduling decisions.

Step 1 is now Pass/Fail — why does this show a 3-digit score?

Since January 2022, Step 1 results are reported as Pass/Fail only. The 3-digit score shown here is an internal benchmark useful for gauging readiness and tracking week-over-week progress — not an official reported score.

What's a safe Step 1 score before scheduling?

The community-accepted safe zone is 210+. The official passing threshold is 196. Aim for 210+ on at least two recent forms before scheduling to give yourself a comfortable margin.

Why does each NBME form use a different formula?

Each form has a unique difficulty distribution. The same number of wrong answers on NBME 25 and NBME 31 will yield different predicted scores. Always use the formula specific to the form you took.

Is my data saved or shared?

No. All calculations run in your browser. Saved scores go to localStorage only — nothing is sent to any server.
