Step 3 • Live Practice
Computer-Based Case Simulations (CCS)
Built by clinicians, MDSteps CCS Cases simulate real-time patient care: timed orders, evolving vitals, physiology‑driven responses, and outcome scoring. Practice safe, decisive management under pressure.

Filter by system, setting, difficulty, and estimated time. Read the chief complaint and start the clock.
Order tests, meds, and consults; monitor vitals; advance the timeline. Safe‑order prompts reduce unforced errors.
Outcome score, annotated timeline, and why‑right/why‑wrong rationales with key learning points per decision.
CCS Cases for USMLE® Step 3: Practice Management That Mirrors the Exam
Preparing for USMLE Step 3 means demonstrating safe, efficient patient management across emergency, inpatient, and clinic settings. Our library of computer-based case simulations (CCS cases) is designed to build the exact skills the exam measures: prioritizing critical actions, placing appropriate next-best orders, tracking vitals and labs in real time, and choosing the right disposition. Each case includes concise teaching points and outcome-based feedback so you understand why a plan works—not just which orders to click. Whether you’re tightening sepsis resuscitation, managing DKA, or navigating postpartum hemorrhage, practicing with realistic CCS scenarios helps convert guidelines into fast, exam-day decisions and stronger clinical judgment.
