The AI-Powered Q-Bank for USMLE Step 2 CK.

Master the Step 2 blueprint with 15,000+ adaptive questions, an AI performance dashboard, and a system built on proven cognitive science.

Study Smarter, Not Harder.

Traditional Q-banks rely on brute force. iatroX is built on proven cognitive science to make your study time more efficient.

1. Active Recall (The Testing Effect)

Retrieving information is proven to build stronger memories than passive reading. Our entire platform is a powerful active recall engine.

(source: Karpicke, J. D., & Roediger, H. L. (2008). The Critical Importance of Retrieval for Learning.)

2. Spaced Repetition (Long-Term Retention)

Our algorithm schedules questions at the perfect, increasing intervals to interrupt the 'Forgetting Curve,' locking knowledge into your long-term memory.

(source: Ebbinghaus, H. (1885). Memory: A Contribution to Experimental Psychology.)
Meticulously Mapped to the Step 2 Blueprint.

Stop guessing if you're covering the right material. Our content is mapped directly to the USMLE Step 2 CK blueprint, ensuring every minute you study is high-yield.

Our 15,000+ questions cover the full range of physician tasks and clinical science categories, from 'Patient Care' and 'Diagnosis' to 'Pharmacology' and 'Physiology,' just like the real exam.

Your Personal AI Tutor.

Go beyond simple 'percent correct.' Our AI Performance Dashboard gives you actionable insights, just like a 1-to-1 tutor.

Mastery Learning

Visually track your proficiency by topic. Our dashboard helps you apply 'Mastery Learning' to focus *only* on what you haven't mastered.

The 2 Sigma Problem

Your AI dashboard provides the 1-to-1 guidance proven to be **two standard deviations** more effective than conventional study.
