Could you build this?
Partial The test engine, adaptive testing algorithm, and study plan UI are standard web features, but acquiring and validating 13,000 accurate SAT questions aligned with testing standards requires heavy domain content authoring.
What it would actually take: The technical platform is a Next.js frontend with PostgreSQL and Item Response Theory (IRT) algorithms to calibrate question difficulty dynamically. The core obstacle is creating, tagging, and psychometrically validating a massive proprietary question bank (13,000+ items) with detailed answer rationales, requiring experienced educators and test-prep curriculum writers.
