Hadas: Bagrut, Never Forgotten

The material was never the problem. Forgetting it was.

Most of what you studied this month will fade before the exam — not because you didn't understand it, that's just how memory works. Hadas is the engine that stops it: you answer a question, the system measures how stable that memory actually is, and brings it back right as it starts to fade, paced to the exam date you set.

How it works • You recall, you don't re-read — every item ends in a question you answer, including open-ended writing prompts with a self-grading rubric. Active recall is what makes it stick, not rereading or highlighting. • The engine tracks what you're forgetting — every answer updates a memory model (FSRS) for that item, and paces reviews against days left to your exam. • It comes back at the right moment — a notification arrives right when something is about to be forgotten, so you don't have to remember to open the app.

What's inside 8 high-school subjects: Hebrew Bible, Hebrew language, literature, history, civics, English, math and biology — plus a separate middle-school track. Hundreds of topics mapped to the official Israeli Bagrut exam questionnaires, with an exact source for every claim.

• Questions at real Bagrut exam level, not trivia • Step-by-step guided solutions in math and biology • Podcasts and videos for dead time, sorted by what you're studying now • Per-topic mastery tracking: mastered, learning, still waiting • 1-on-1 duels and a weekly class leaderboard
