Stage 1 · Diagnose
15 questions. Your map.

Things People Ask
Quick answers.
Three things must be true: (1) you used Sia at least 8 hrs/week for 28 weeks, (2) you completed all 5 stages, (3) your official AP Statistics score landed below the target you set in onboarding. Then: 100% refund, processed within 30 days.
Sia teaches the decision tree: (1) categorical or quantitative? (2) one sample or two? (3) test or interval? Reflex application beats memorization. Most 5-scorers reach reflex by week 8.
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.
Critical. Missing conditions = -1 point per FRQ. Sia drills the conditions for each procedure as a 3-item checklist that becomes a habit. 6 FRQs × conditions = 4-6 points you can't afford to skip.
Princeton Review Premium sells content. AskSia sells the outcome. You pay $149, we promise your AP Statistics target — or 100% refund. Princeton Review Premium doesn't make that promise. That's the difference.
Often. About 40% of our students say their school's AP class doesn't cover the FRQ rubric well. Sia's cheat sheets + FRQ archetype drill close the rubric gap regardless of teacher quality.
