NBMEcalculator

NBME Calculator is an independent educational tool designed to help medical students preparing for USMLE Step 1 and Step 2 CK interpret their practice exam performance more clearly. Its main purpose is to convert NBME, UWSA, and Free 120 results into an estimated 3-digit USMLE score, giving users a practical way to understand readiness before test day. The tool lets users choose an exam, select a specific form, and enter either their number of incorrect answers or percent correct. It then provides a predicted score, pass probability, and readiness verdict. For example, a Step 1 student who completes NBME 31 can enter the number of questions missed and immediately see whether the result falls near the passing threshold or a safer preparation range. A Step 2 CK student can compare scores from NBME 10, NBME 13, and UWSA 2 to understand whether their performance is improving. NBME Calculator is useful for students planning a dedicated study period, deciding when to take another practice form, or evaluating whether they are ready to schedule the real exam. It supports major active Step 1 and Step 2 CK practice forms and also includes a score tracker, so users can save results locally, review previous attempts, compare latest and average scores, and view progress over time. The main benefit is clarity. Instead of guessing what a raw practice score means, students can turn results into an actionable estimate, identify trends, build a score buffer, and make more confident study decisions. It is not an official NBME or USMLE product, but a practical planning companion for exam preparation.
