Things People Ask

Quick answers.

It's the simplest contract in test prep. Spend 30 weeks with Sia on AP Computer Science Principles. If you miss your target, every cent comes back. Counsel-vetted terms. No fight, no questionnaire, no fine print.

Late April (Apr 30, 2027). The CPT is 30% of your grade and CANNOT be late. Sia gives you a 6-week guided build with 3 review checkpoints aligned to the College Board rubric.

International by design. Multilingual UI, async throughout, content calibrated to the international student profile (which is most of our cohort).

Yes, considerably. CSP teaches concepts; CSA teaches Java programming. CSP's 5-rate is ~13%, CSA's is ~25%. But CSA is more valued by CS majors. Sia helps you pick the right path.

Three things Princeton Review Premium doesn't include at any price: (1) a personalized topic-frequency × your-accuracy map, (2) real-time mock score prediction calibrated quarterly, (3) a refund tied to your official AP Computer Science Principles outcome. We do, for $149.

For a 5-target, start in September. For a 4-target, January works. Sia calibrates the weekly hours to your start date so the load stays manageable until April.
