About
Built by an educator. Taught by vetted specialists.
A curated tuition agency, not a marketplace. Every tutor on our small bench is personally vetted by our founder, and every claim on this page is built on the same conviction: 0606 grades are built from marked working, not motivational speeches.
The educator who vets your child's tutor
Rig
Founder · IGCSEAddMath.com.my
- Mechatronics Engineering, Universiti Teknologi Malaysia (UTM)
- 8 years teaching IGCSE & SPM Math and Add Math
- 9,000+ subscribers watching his free math teaching videos on YouTube
- Personally interviews and vets every Add Math tutor on this service
Rig trained as an engineer, then spent the last 8 years doing something engineers rarely do: teaching. Thousands of hours of 1-to-1 IGCSE and SPM Math and Add Math classes, and a YouTube channel of free add math lessons that has grown past 9,000 subscribers. He knows, from the inside, exactly what excellent exam-focused teaching looks like and how rare it is.
That's why this service exists. Instead of scaling his own teaching hours, Rig now applies that educator's standard to a different problem: finding and vetting Cambridge IGCSE Add Math specialists, so parents don't have to gamble on a stranger. Every Add Math lesson is taught by a vetted specialist. Rig's job is making sure nobody joins the bench who doesn't teach to the standard he held himself to. A tutor who cannot teach to that standard never meets your child.
How our tutors are selected, and how your child's tutor is assigned
We keep the tutor bench deliberately small. Every tutor is personally vetted by Rig, tested on 0606 mark-scheme fluency and observed teaching, then briefed on our method before taking a student. We assign your child a tutor from that bench — every tutor meets the same quality bar — and the 1-hour trial class is the compatibility check before you commit to a weekly slot.
Vetted by the founder
Every tutor is selected by Rig for 0606 depth, with mark-scheme fluency tested and teaching observed, then briefed on our method before taking a student.
Assigned from the bench
You never pick from a directory of strangers. We assign your child a tutor from our small vetted bench — every tutor on it has passed the same quality vetting.
Proven in the trial
The 1-hour trial class is the compatibility check: your child meets their tutor before you commit to a weekly slot, and the same person teaches every week after.
What students say about our founder's teaching
These are from students Rig taught personally, in his classes and through his free video lessons — the same mark-scheme standard every tutor on our bench is tested against before they teach. The trial class is where you verify it on your own child.
