Things People Ask
Quick answers.
Three things must be true: (1) you used Sia at least 8 hrs/week for 16 weeks, (2) you completed all 5 stages, (3) your official USMLE Step 2 CK score landed below the target you set in onboarding. Then: 100% refund, processed within 30 days.
Since Step 1 went P/F, Step 2 CK became the primary residency screening number. Sia's drill is calibrated to the 260+ band — what competitive specialties (ortho, derm, plastics) require.
Built for it. The Sia interface runs in Korean, Chinese, Spanish, and Japanese. All sessions are async — no live class times to chase. International cohort: 22 countries strong.
Most students take it during/after IM clerkship, 16-24 weeks after Step 1. The new Match timeline rewards earlier Step 2 reporting. Sia helps you optimize the calendar.
UWorld Step 2 CK sells content. AskSia sells the outcome. You pay $149, we promise your USMLE Step 2 CK target — or 100% refund. UWorld Step 2 CK doesn't make that promise. That's the difference.
Minimum 4 NBME practice tests. Most 250+ scorers do 6-8. Sia spaces them every 2 weeks across dedicated, with topic-by-topic post-mortem after each.
