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.

  • Level 0 — Quick MCQ, right after you've learned it.
  • Level 1 — Hint recall, with a small nudge.
  • Level 2 — Pure recall, no hints.
  • Level 3 — Timed recall, against the clock.
  • Level 4 — Applied, a twisted question that makes you use the idea.
  • Level 5 — 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. Mark a topic as weak and it comes back sooner; get it wrong and it's due again tomorrow, whatever level it was on. You never drop more than one level back, 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 two-week heatmap 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".

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. Mark each answer right, wrong or weak, and the next revision schedules itself automatically. The questions are generated for your exact subtopic, so you're revising what you're actually studying — not a generic deck.

Frequently asked questions

What is spaced revision?
Spaced revision (or spaced repetition) brings each topic back to you at gradually widening intervals, just before you'd forget it. Lighthouse Prep adds a twist: every time you get a topic right, the next question on it is harder — so you're always tested at the edge of what you know.
How do the six levels work?
Each topic starts at Level 0 with a quick MCQ and climbs to Level 5 (mastered). The levels go MCQ → hint recall → pure recall → timed recall → applied question → mastered, and the gap before a topic is due grows as it climbs — from about a day up to two months.
What happens if I get a question wrong or mark it weak?
If you get it wrong, the topic is due again tomorrow no matter what level it was on. If you mark it weak, it simply comes back sooner. Either way you never drop more than one level, so the system is forgiving by design.
Do I have to plan my own revision schedule?
No. After each session the next revision date is set for you automatically, based on how well you did. A Due Today banner and a two-week heatmap show you what's coming so nothing piles up.
Is it free?
The spaced-revision system — scheduling, levels and due-today tracking — is free to use. The AI that generates each revision question uses a small token balance, and you start with a free amount.
Can I use it for current affairs too?
Yes, for any topic you add as a study session and generate revision questions for. The day's current-affairs MCQs don't drop into your revision queue automatically — add the topic as a session if you want to revise it this way.
