Disclaimer

In plain English: This is a free study tool. Every score and pass probability it shows is an estimate built from community-reported data, not an official result. Use it to guide your studying and track your progress — never as the sole basis for a high-stakes decision like booking your exam. We are not affiliated with the NBME® or USMLE®, and nothing here is medical advice.

Educational use only

This website provides free calculators, converters, and reference material to help medical students interpret their NBME and UWorld self-assessment results. Everything on it is offered for general educational and informational purposes. It is not professional, medical, academic, or test-preparation advice, and it does not create any advisor, tutor, or professional relationship between you and us.

Estimates, not official scores

The three-digit scores and pass probabilities produced here are statistical approximations derived from conversion patterns that students report and discuss publicly. They are not generated by, verified by, or sourced from the exam makers, and they will not always match your official result. Individual performance varies with test-day conditions, content sampling, fatigue, and ordinary day-to-day variation. Treat any number you see as an approximate signal with a real margin of error, and read the direction of travel across several sittings rather than trusting a single figure. Our methodology page explains exactly how each estimate is built and where it can go wrong.

Not a substitute for official materials or advice

Our tools do not replace official score reports, guidance from your medical school, or the resources published by the organizations that administer these examinations. For authoritative information about registration, scoring, passing standards, and policies, always rely on official sources. Do not make irreversible decisions — such as scheduling or rescheduling an exam — on the basis of an estimate from this site alone.

No medical advice

Reference content such as lab-value ranges is included as a study aid only. It is not medical advice and must never be used to diagnose, treat, or manage any person's health. If you need medical guidance, consult a qualified healthcare professional.

No guarantee of outcomes

We work to keep our models and content accurate and current, but we make no warranty that any estimate, figure, or statement here is complete, reliable, or error-free. Using this site is at your own discretion, and we accept no liability for decisions made in reliance on it.

External links

Some pages link to third-party websites for convenience. We do not control and are not responsible for the content, accuracy, or practices of those sites. Visiting them is at your own risk.

Trademarks and affiliation

Not affiliated with, endorsed by, or sponsored by the NBME® or USMLE®. Educational estimates only. NBME®, USMLE®, and any other marks referenced on this site belong to their respective owners and are used only to describe the assessments our tools estimate.

Changes

We may update this disclaimer from time to time. Any changes take effect when we post the revised version on this page.
