The Memento Method
Diagnose → Practice → Retain
There is no fixed track. Your learning plan evolves to your level constantly.
Practice
Work at the edge of your ability.
Questions, examples and feedback adapt to what is optimally challenging right now.
Retain
Review before forgetting.
Spaced review revisits material at the right intervals, feeding back into the knowledge graph.
Every interaction is an input.
Even correct answers contain valuable diagnostics.
Comprehension, writing, vocabulary and review evidence all recalibrate the same knowledge graph.

What learners and parents ask us.
Is Memento really free?
Yes. Memento is in beta and the entire product is free while we build it with learners, parents and tutors.
What is a knowledge graph?
It is Memento’s changing model of the skills a learner can use securely, the areas that need more evidence and the next skills they are ready to tackle.
Does one mistake lower a student’s level?
No. Memento looks for patterns across different tasks. A single response adds evidence; it does not erase prior performance or permanently label a learner.
Can a student move ahead of their class?
Yes. Practice is organised around readiness rather than a fixed weekly schedule, so students can move quickly where learning is secure and slow down where it is not.
Which exams does Memento support?
HKDSE English is live in beta. IELTS preparation is coming soon, and the underlying comprehension and writing system is designed to work beyond any single exam.
