The Challenge

Generic Study Plans Were Wasting Precious Prep Time

Students spent countless hours studying content they'd already mastered while neglecting weak areas. Generic test prep forced everyone through the same material regardless of individual knowledge gaps. Score plateaus were common, motivation dropped, and pass rates remained frustratingly low despite massive time investments.
