Built for the way memory actually works.

Not cramming. Not bottomless decks. A short daily session that puts each word in front of you right as it's about to slip.

Paced to your exam date

You tell ObaPrep when you test. It schedules every word to come back right before you'd forget it, so nothing leaks out before exam day.

Real questions, not just definitions

You see each word the way the GRE actually uses it, in context, instead of memorizing flashcards in a vacuum.

Recall, not just recognition

Typing and retrieval beat passive flipping. ObaPrep makes you produce the word, so it's there when the question is.

A look inside.

See a word, wrestle with it, lock it in. The whole loop, in a few minutes a day.
