How learning works

Readiness-based; a 32–36-week school route can allocate several sessions and review tasks per lesson group. Timing is a proposal, not calibrated.

No timers. Reviews come back after 1, 7, 21 days. Reading a lesson is not mastery; you finish after attempting core lessons, checked written work and a delayed review.
