The problem
Cramming feels productive and fades quickly.
Children often understand something in the moment, then lose access to it weeks later. That is not a character flaw; it is how memory behaves without planned retrieval.
Memory schedule
Important concepts return before they disappear.
This page explains the memory layer: why a concept learned today must be seen again at the right time if it is expected to last.

The mechanism
Review is scheduled from evidence of fragility.
SupΣrLearnΣr brings concepts back across days and weeks, with more attention to ideas that look unstable or foundational.
The parent view
Revision stops being a household project.
Parents no longer need to remember which topic should return. The system keeps a review queue and explains why a concept is coming back.
What this creates
Concrete product signals parents can understand.

Parent takeaway
The system protects what your child has already learned, so understanding has a better chance of surviving exam season.
