Mastery
Do not rush ahead when a core skill is still fragile.
Learning science
Why targeted practice beats more practice.
Mentora turns established learning principles into practical decisions: repair the prerequisite, review a fragile skill, check readiness, or move forward.
Small steps, timed well.

Principles
Learning is conditional, so practice should be conditional too.
A student may need a smaller repair, a fluency review, or a harder question depending on what their last answer revealed.
Mastery learning
Students move on when the foundation is steady enough, not simply because a chapter is finished.
Active problem solving
Practice works when students solve, get feedback, and adjust the next attempt.
Cognitive load
Tasks should be small enough to attempt when a learner is fragile, then widen as fluency grows.
Spaced review
Older ideas need to return before they fade, especially when harder topics depend on them.
Mixed practice
Once the pieces are ready, students practise choosing the right method across topics.
Prerequisite layering
New topics become stronger when earlier ideas are reused in richer contexts.
Product translation
Mentora turns learning science into task choices.
The product does not show students a research paper. It turns the principles into a practical next step that is specific enough to do.
Prerequisite repair
Step back to the smaller missing idea before repeating harder questions.
Cognitive load
Keep repair tasks narrow enough that the student can make progress today.
Spaced review
Bring back older skills before they become hidden blockers.
Mixed practice
Combine topics after the student can handle the individual pieces.
Prerequisite repair
Hard questions become reachable when the missing step is repaired first.
If a student keeps struggling with a harder topic, the best next task may be an earlier concept. That is not going backwards; it is repairing the part that lets the student move forward.
Blocked
More hard-topic practice repeats the same error.
Repair
A smaller prerequisite task fixes the missing step.
Check
A readiness question confirms the repair is holding.
Advance
The harder topic returns when the foundation can carry it.
Spacing
Review works best before a skill fades.
Day 1

Day 3
Light recall
Day 8

Day 21
Use inside harder topic
Plain-English rule
Do the smallest task that makes the next important skill more reachable.
This keeps the task narrow when the learner is fragile and lets the system broaden practice as readiness improves.
