About Us
NBMEScore.com is an independent, free medical education platform built to help medical students understand, analyze, and act on their USMLE Step 1 practice exam performance. We started with a simple observation: students were spending hours manually calculating NBME scores from Reddit spreadsheets and getting the wrong answers — and even when they got the number right, they had no idea what to do next.
We built NBMEScore.com to fix that. Every calculator on our site uses a form-specific, validated regression formula — covering NBME Forms 25 through 31 for Step 1, NBME Forms 9 through 15 for Step 2 CK, and both UWorld Self-Assessments (UWSA1 and UWSA2). Every score comes with context — pass probability, performance summary, weak area analysis, and a direct path to a personalized study dashboard. All of it, completely free.

Our Approach to Accuracy
Every formula on NBMEScore.com is derived from community-validated regression data — the same sources used by Step 1 prep educators and medical students worldwide. We use form-specific formulas rather than generic approximations because each NBME form has a different difficulty calibration. NBME 25 is not the same as NBME 30, and our calculators reflect that.
We publish our formulas openly on every calculator page so students can verify the math themselves. Transparency is not optional for us — it is the foundation of what we do.
