NBMEcalc helps medical students interpret Clinical Science Mastery Series (CMS) form results during USMLE Step 2 CK preparation. Enter a CMS score or percent-correct result to review subject-level study signals across Internal Medicine, Surgery, Pediatrics, Obstetrics and Gynecology, Psychiatry, and Family Medicine.

The guide explains how CMS reports can inform rotation-specific study priorities and why a subject-focused CMS result should not be treated as a direct official Step 2 CK score conversion. Learners can use the resource alongside comprehensive readiness assessments when planning their next study block.

NBMEcalc is free to access in a browser. It is an independent educational planning resource and is not affiliated with, endorsed by, or sponsored by NBME or USMLE.

Questions & Answers

As answered by people managing Protocol Deviation and NBMEcalc.

What makes your product unique?

NBMEcalc's answer:

NBMEcalc combines multiple practice assessment sources—including NBME, UWSA, Free 120, AMBOSS Self-Assessment, and CMS—into one USMLE planning range. Instead of presenting a single “magic” score, it shows a 95% confidence interval, supports Step 1, Step 2 CK, and Step 3, and makes its methodology and limitations public.

Why should a person choose your product over its competitors?

NBMEcalc's answer:

NBMEcalc is designed for students who want to interpret several practice assessments together rather than relying on one score in isolation. The core predictor is free, works without registration, supports multiple assessment sources, and clearly communicates the uncertainty around every estimate.

How would you describe the primary audience of your product?

NBMEcalc's answer:

NBMEcalc is built for medical students and graduates preparing for USMLE Step 1, Step 2 CK, or Step 3. It is especially useful for test-takers who have results from several practice assessments and need a clearer view of their score range, pass readiness, and study trajectory.

What's the story behind your product?

NBMEcalc's answer:

NBMEcalc began in late 2025 after frustration with closed-source score predictors and one-size-fits-all advice. The first prototype was created to combine multiple practice assessment sources into a more transparent planning range. The project later added a public methodology, confidence intervals, free score prediction, downloadable reports, and multi-exam tracking.

Which are the primary technologies used for building your product?

NBMEcalc's answer:

NBMEcalc is a responsive browser-based application built with Next.js, React, and TypeScript. It uses statistical score-normalization and weighting logic to combine multiple practice assessment results. The application is mobile-friendly and can be used directly in a web browser without installing native software.

Who are some of the biggest customers of your product?

NBMEcalc's answer:

  • Medical students preparing for USMLE Step 1
  • Medical students and graduates preparing for USMLE Step 2 CK
  • Medical graduates preparing for USMLE Step 3
  • International medical graduates preparing for USMLE examinations
