The lesson.
The theory for the sub-strand, written for the grade it belongs to: the explanation, the worked examples, the vocabulary a learner needs before they touch anything else.

Adaptive learning loop
Learn, Practise, Test — get adaptive recommendations for your weak areas.
Every subject moves through the same four stages. The last one reads the learner's competency and recommends the interactive learning materials in the library that close the gap, so the loop tightens each time round.
The activity.
Practice built for what was just taught — questions, investigations and practicals a learner works through to turn the reading into a skill.
Practice setsInvestigationsPracticals
The competency assessment.
A CEA closes the sub-strand and scores the competency itself, not a percentage — where the learner is strong, where the gap is, and how wide it is.
Auto-markedCompetency-levelPartial credit
The recommendation engine.
The result routes the learner back into the library: the lessons and activities that address the weak competency first, ranked by what will move it most.
Reads the CEARanks the materialQueues it up
Stage 4 feeds stage 1. A weak competency becomes the next lesson — not a note in a report nobody acts on.
For teachers
A whole week of lessons, in three steps.

Continuous Evaluation Assessments
/ˈsiː·iː·eɪ/ · the heart of CBE
Self-evaluation, at whatever size the learner needs.
A learner tests their own competency whenever they want — on one sub-strand, a whole strand, or the entire subject. Questions are drawn at random, so the same set never comes round twice. Grade 9 learners can use the same CEAs to revise for KJSEA.
Just finished a sub-strand? Test it now.
The narrowest check there is: random questions drawn from that one sub-strand, marked the moment it is submitted. Useful the same evening the lesson was taught.
Test a whole strand at once.
A wider spread across every sub-strand in the strand, so a learner can see which part of it is actually weak rather than guessing.
Sit the whole subject.
Every strand in the book, sampled at random. The result is a competency picture of the subject — and the recommendation engine reads it to pick what to study next.
Revise for KJSEA, strand by strand.
Grade 9 learners can work the whole Grade 7–9 syllabus through CEAs — pick a subject, see which strands are still weak, and revise those first instead of re-reading everything.
Who it's forTeachers Parents Students
One product, three real roles.
Plan, deliver, reflect.
Assign this week's lessons in under an hour. Save your best material to a personal library that travels with you between schools.
Stay in the loop, without homework drama.
Add your child, pick the grade. Run a CEA on Saturday. Top up tokens with M-Pesa. See weak strands at a glance.
Sign in with a PIN. Get sharper every week.
Use the family phone — no email required. Take CEAs, watch your weak strands shrink, build a streak you'll defend.
The first tool that actually understands the strand structure instead of treating it as a folder name.
