USMLE Step 3 Prep: Format & Practice
USMLE Step 3 is the final exam in the US medical licensing sequence, usually taken during residency. It runs over two days — Foundations of Independent Practice (multiple-choice blocks) on day one, and Advanced Clinical Medicine blocks plus computer-based case simulations (CCS) on day two. Here's how it's structured — with realistic COSMIQ practice.
COSMIQ prepares you for the USMLE Step 3 and administers realistic full-length mock tests — it does not administer the real exam or issue a medical license.
Frequently asked
What are the two days of USMLE Step 3?
Day 1 (Foundations of Independent Practice) is multiple-choice blocks covering foundational science, biostatistics, and pharmacology; Day 2 (Advanced Clinical Medicine) adds more multiple-choice plus computer-based case simulations (CCS), where you manage simulated patients over time.
Does COSMIQ issue a medical license?
No. COSMIQ prepares you for USMLE Step 3 and administers realistic practice — it does not administer the real exam or issue a medical license. Licensure comes from your state medical board.
