For the Psychometric and the English Bagrut. 300 academic words, six weeks, five minutes a day. The vocabulary that wouldn't stick from a word list — finally sticks. You know the cycle. You open the list. You get through forty words. A week later "perfunctory" is gone again. Lists don't fail because you weren't trying — they fail because the word never had anywhere to live. Dopus drops every word inside a small, specific scene. A returned essay with one word circled in red. An apology that lands wrong. A street sign you don't quite read. You guess the meaning from the scene, and that guess is the thing your brain holds onto. THREE PHASES, BUILT FOR REAL MEMORY • Recognize — the word arrives inside a moment your brain can picture, with the definition close enough to reach for. • Understand — the training wheels come off. You apply the word in context, without the clue. • Mastery — the word returns just before you'd forget it, in a new scene every time, until it's locked in for good. Behind every question is FSRS, the most accurate spaced-repetition algorithm available — running quietly so you don't have to think about when to review.
