Step 3's Secret Weapon

Clinical Rounds

Your own virtual clinic. Practice patient cases with AI simulation, just like the CCS portion of Step 3.

Solve Real cases. Improve decisions.

Step 3's CCS component isn't about knowing facts—it's about managing patients over time. Clinical Rounds lets you practice exactly that.

🏥 Manage virtual patients, take history, order tests, make treatment decisions
⏱️ Time-based simulation, cases evolve, just like real patients
🎯 Instant feedback, learn what you missed and why

The Reality

You're a resident. When are you supposed to study?

⏰

80-hour weeks

Call nights, patient loads, documentation. Finding 30 minutes to study feels impossible.

🎮

CCS is different

Day 2 isn't MCQs—it's case simulations. You need to practice managing patients, not just answering questions.

📋

License deadline

Many programs require Step 3 by PGY-2. The clock is ticking.

The Reality

You're a resident. When are you supposed to study?
