Secure
Linear equations
Ready to use inside later algebra.
Course
O-Level E-Math revision that adapts to you.
This is Mentora's first live course: a focused path through the Singapore-Cambridge O-Level E-Math syllabus. Start with a diagnostic, repair weak foundations, and build back to exam-style questions when ready.
Course snapshot
Exam readiness depends on the foundations underneath.
Ready
Expansion
Can expand brackets with light review.
Weak link
Factorisation
Mistakes repeat when reversing expansion.
Blocked
Quadratic graphs
Current work should wait until factorisation is repaired.
Today's course decision
Spend the next short session rebuilding factorisation, then check readiness for quadratic graphs.
Find your starting point
The diagnostic checks enough of the syllabus map to begin where revision is most useful, not just at chapter one.
Follow a focused path
Each session chooses a repair, review, readiness check, or exam-style task from your latest work.
Build back to exam work
Harder mixed questions return when the foundations underneath them are ready enough.
Knowledge map
O-Level E-Math is hundreds of connected ideas.
The real map has 443 micro-concepts and 1,760 relationships. This preview shows why Mentora does not simply follow the textbook chapter order: a small prerequisite can unlock several later topics.
How to read the map
Green nodes are secure, yellow nodes are nearly ready, orange nodes need repair, and red nodes are current topics that become inefficient until the weak prerequisite is fixed.

Algorithm takeaway
The fastest path is the prerequisite with the most useful downstream unlock.

Why it matters
If factorisation is shaky, more quadratic graph practice can look productive while the real blocker remains untouched.
