How AskSia Gets You There
5 stages. One path. Every stage has a tool you won't find anywhere else.
Click any stage on the left to see exactly what you get. No fluff. No filler.
Stage 1 · Diagnose
15 questions. Your map.
Sia pulls from the Library — official past AP Computer Science A papers analyzed by our content team. You take a 15-question diagnostic. Sia returns a topic frequency × your accuracy map. Now you know exactly where every point lives.

Stage 2 · Learn
12 cheat sheets. One page each.
Other prep shows you thousands of questions. We show you the patterns that generate them. Each AP Computer Science A topic compressed into one page — concept · trap · scoring rule. Top-down learning. Built by our content team, not auto-generated.

Things People Ask
Quick answers.
No catch — but real conditions. 30 weeks of consistent use (8+ hrs/week across all 5 stages), an official AP Computer Science A score below your stated target, refund within 30 days. Receipts published.
Java fluency is the prerequisite. If you're starting from zero, you need 12+ weeks of Java basics before AP CSA prep makes sense. Sia tracks your Java syntax errors and remediates them automatically.
Designed for it. Four-language native interface (Korean, Chinese, Spanish, Japanese). Fully async, so timezone is irrelevant. Our cohort spans 22 countries.
CSA is Java programming (write code). CSP is computational thinking (concepts + a portfolio + an exam). CSA is harder but valued more by CS majors. Sia distinguishes them clearly so you pick right.
Two structural reasons. (1) No human-tutor payroll — Sia is AI-native, not a video library wrapped in a marketing spend like Princeton Review Premium. (2) Launch pricing; this $149 won't last past Cohort 1. The Guarantee is what makes the cheap version real.
Yes — Sia is designed for the 3-5 AP load. The diagnostic identifies which topics within AP Computer Science A you can skip (because your class covered them well) and which need extra drill.
