NBMEcalculator

NBME Calculator is a free web tool for medical students who want a clearer read on practice exam performance for USMLE Step 1 and Step 2 CK. Enter your exam type, pick a specific NBME, UWSA or Free 120 form, and supply either percent correct or number wrong; the site returns a predicted three-digit USMLE score, a pass probability and a basic readiness verdict.

Each practice form is handled separately because forms vary in length, difficulty and scoring. The tool covers Step 1 forms (NBME 25–31, UWSA 1, UWSA 2, Free 120) and Step 2 CK forms (NBME 9–15, UWSA 1, UWSA 2).

• Instant score conversion and pass probability
• Form-specific calculations for common NBME/UWSA/Free 120 exams
• Local score tracker that saves results in your browser to compare recent and average performance
• Additional pages with score benchmarks, exam scheduling info, form sequencing advice and FAQs
