THE STORY
Built for One Student. Created for Every Student.
SAT Prep Mastery began when Lindsay, then a high-school junior preparing for the SAT, asked her dad whether they could build something better than the expensive courses, generic free question banks, and limited tutoring options she was finding.
What started as a study tool for one student became a father-daughter project shaped by Lindsay’s perspective as an actual SAT student and her dad’s experience building apps. Lindsay helped push the platform toward harder questions, deeper explanations, AI tutoring, structured study plans, Desmos integration, better student-friendly layouts, and now a mobile app (coming soon).
