What is spaced repetition?

A review schedule that re-asks material just before you would forget it, at growing intervals - here 1, 3, 7, 14 and then 30 days. Decades of research, including a 2026 meta-analysis across more than 21,000 learners, find it beats ordinary re-reading by a wide margin.

Where do the review questions come from?

From the end-of-lesson quizzes of Primer Path lessons you have already completed on this device. Answer correctly and a question moves to a longer interval; miss it and it comes back tomorrow.

Review — make what you learned stick

Reading a lesson once is how knowledge arrives. Being asked again on day 1, 3, 7, 14 and 30 is how it stays. This page re-asks the quiz questions from lessons you have completed — on exactly that schedule.

Why this works

Everyone forgets most of what they read once — that is normal memory, not a personal failing. What changes the outcome is retrieval at spaced intervals: being made to recall something just before it fades. A 2026 meta-analysis in The Clinical Teacher, covering fourteen studies and more than 21,000 learners, found large, statistically significant gains for spaced repetition over standard studying. Flashcard tools like Anki are built on the same principle; here it is applied to trading concepts.

The schedule is simple: a question you answer correctly moves out — 1 day, then 3, 7, 14, and 30. A question you miss resets and returns tomorrow. Over a few weeks the deck sorts itself: the ideas you truly know stop bothering you, and the ones you only think you know keep showing up until they stick — which matters in trading, where a half-remembered rule tends to cost real money.

Your deck and schedule are saved on this device (and sync with your journal sign-in progress where available). Completing a lesson on the Primer Path automatically adds its questions here.
