GRE prep often involves memorizing obscure vocabulary, but generic flashcard apps don't adapt to test patterns.
Build an app that uses spaced repetition algorithms tailored to GRE word frequency and question types. Include mnemonics and example sentences.
Students pay for premium word lists and progress tracking. Partner with prep courses for bundled access.
MVP: A basic flashcard app with GRE word list and simple spaced repetition.
