How realistic is the CCS simulator compared to the actual exam?

Our simulator closely mirrors the official NBME CCS software. We've designed the interface, order entry system, and timing to match the real exam as closely as possible. Many users report that the actual exam felt familiar because of their practice with MasterCCS.

Does the timing and flow match the real CCS exam?

Yes. Each case in our simulator runs for the same 10-20 minutes as real CCS cases, with the same time advancement mechanics. Our full-length exam mode includes the same number of cases and total time as the actual Step 3 CCS component.

How does the AI tutor work?

Our AI tutor analyzes your decisions in real-time and provides context-aware guidance. It explains why certain orders are appropriate, suggests next steps when you're stuck, and provides detailed feedback after each case. Think of it as having an attending available 24/7 to explain clinical reasoning.

Can I cancel my subscription anytime?

Our plans are one-time purchases for a set duration, not recurring subscriptions. Once you purchase access, you have full access for that time period with no additional charges or cancellation needed.

What if my exam is very soon?

Our 1-week plan is designed exactly for this situation. Many residents successfully use MasterCCS for last-minute preparation. The AI tutor helps you learn efficiently, and even a few days of focused practice can significantly boost your confidence and performance.

Do you offer refunds?

All sales are final. We encourage you to try our free cases before purchasing to make sure MasterCCS is the right fit for your study needs.

How many CCS cases are included?

All plans include access to our full library of 175+ CCS cases covering all major specialties and common clinical scenarios. We regularly add new cases to keep the content fresh and comprehensive.
