Things People Ask
Quick answers.
No catch — but real conditions. 12 weeks of consistent use (8+ hrs/week across all 5 stages), an official OAT score below your stated target, refund within 30 days. Receipts published.
Geometric optics dominates: mirror/lens equations, sign conventions, refraction. Sia drills 100+ optics problems matched to OAT exam style.
Designed for it. Four-language native interface (Korean, Chinese, Spanish, Japanese). Fully async, so timezone is irrelevant. Our cohort spans 22 countries.
OAT for optometry school. DAT for dental school. They overlap on bio/chem but differ on Physics (OAT only) vs PAT (DAT only). Sia covers both with exam-specific drill.
Two structural reasons. (1) No human-tutor payroll — Sia is AI-native, not a video library wrapped in a marketing spend like Kaplan OAT. (2) Launch pricing; this $149 won't last past Cohort 1. The Guarantee is what makes the cheap version real.
Yes. The Sia cohort is ~60% working professionals. Plan averages 10-15 hours/week with weekend mock blocks. Async — no live class to miss.
