Spaced revision that makes every topic stick.

Revision that gets harder as you master a topic

Re-reading the same notes doesn't tell you what you'll actually remember on exam day. Lighthouse Prep's spaced revision schedules each topic to come back at the right moment — and makes the question harder every time you get it right, so you're always tested at the edge of what you know.

Six levels, from a quick check to a twisted question

Every topic climbs a ladder. Ace a level and it moves up; the next time it returns, the question is tougher and the gap before it's due is longer.

• L1 — Quick MCQ, right after you've learned it.
• L2 — Hint recall, with a small nudge.
• L3 — Pure recall, no hints.
• L4 — Timed recall, ten seconds on the clock.
• L5 — Applied, a twisted question that makes you use the idea.
• L6 — Mastered, refreshed roughly every two months so it sticks.

A forgiving schedule that adapts to you

After each successful revision the topic is pushed further out — about 1 day, then 3, 7, 14, 30 and 60 days as it climbs the levels. A topic asks you three to seven questions and most of them have to be right, so one slip in five doesn't cost you the topic — it just comes back on a shorter gap. A poor run brings it back tomorrow, and you never drop more than one level, so a single bad day won't undo weeks of work.

See what's due at a glance

A "Due Today" banner on your plan groups everything into Urgent, Weak, Due and Strong, and a five-week calendar shows how heavy the days ahead look so nothing piles up by surprise. Each item carries a plain-English hint like "Revise today to retain for 3 days" or "Overdue by 2 days", and on any day with revision waiting you get a single notification — never more than one.

How a revision session works

Tap Revise from the banner or a session card and answer in the format that matches the topic's level — multiple choice, written recall, or an applied problem. Then you see the real answer and say how it went: got it, partly, or missed it. The app suggests a verdict, but you settle it, because only you know whether it was really in your memory. The next revision schedules itself from there. The questions are written for your exact subtopic, so you're revising what you're actually studying — not a generic deck.
