Free IGCSE Math Diagnostic

They're doing okay in math.
Until suddenly they're not.

Year 7 and 8 marks look fine. Then Year 9 questions start combining topics, and your child cannot start them. By Year 10, revision just moves faster over the same cracks. Usually one cause: a foundation gap nobody checked. This free 10-minute diagnostic finds it, by year level, question by question.

Find the Gap Before the Exam Does Free. 10 minutes. Written by an IGCSE math teacher, not a marketing team.

Which year level is your child in?

Each stage of the IGCSE syllabus leans on a different part of the foundation. Pick your child's year level and the check starts immediately.

free, takes 10 minutes, useful even if everything turns out fine

The part no one warns you about

It looks different at every year level. But it starts in the same place.

Year 7 - 8

"The marks look fine."

A 65 here, a 72 there. But the syllabus at this stage only tests whether your child can repeat a step, not whether they understood it. Gaps hide behind decent marks.

Year 9

"Suddenly they can't start questions."

Questions begin combining topics: fractions inside algebra, algebra inside graphs. The step they needed was half-learned two years ago, and nobody noticed.

Year 10

"Revision isn't moving the marks."

Exam pressure punishes every weak step at speed. Revision does not fix a gap it cannot see, it just moves faster over the same cracks.

Add Math

"Confident, then lost in 3 weeks."

Add Math assumes a fluency that was never confirmed. It is the harshest exposure of a foundation that was only ever assumed solid.

four symptoms. one root cause: nobody checked the foundation while it was still cheap to fix.

"She was getting B's, so I assumed everything was fine. Then in Year 9, she couldn't even start the questions. Not because she didn't study. The basics she needed were never solid. I wish I'd checked earlier instead of trusting the grades."

what we hear from parents, almost word for word

What you'll find out

Which topics are solid. Where the marks are being lost.

Your child answers 8 questions chosen for their year level. You get a plain answer to the question you actually have: is the foundation solid, and if not, where exactly is it leaking marks?

Foundation strength

Whether the core building blocks are actually solid, even when the answers look correct on the surface.

Working and method

IGCSE markers award marks for method, not just the final answer. A right answer with weak working is still losing marks.

Multi-step readiness

The question type where hidden gaps surface first, and where most students start losing marks they shouldn't.

Timing for their year level

What's coming next in the syllabus, and whether the foundation is ready to carry it.

After the diagnostic

We know exactly where your child is stuck. And you see the progress, not just hear about it.

Every gap Teacher Au finds in class goes into your child's Learning Graph. It stays there, named in plain words, until it closes. Once a month you get a card like this one, so you can see which steps are still open, which are improving, and which are gone.

Who's behind this

Not a tuition factory. A teacher who notices.

This diagnostic comes from Teacher Au, who runs small online IGCSE classes where every student has to think out loud and show their working. The questions test the exact steps he watches students stumble on in real lessons. If there's a gap, this is how it surfaces before an exam paper finds it.

Questions

Fair questions. Straight answers.

"Is this just a way to sell me tuition?"
Honestly? It's how some parents find us. But the diagnostic stands on its own: you get a real picture of where your child stands, free, with no follow-up pressure and no sales sequence. If you want to talk about the results afterwards, Teacher Au is one message away. If not, keep the results and use them however you like.
"My child is doing fine. Why would I need this?"
"Doing fine" is exactly when gaps are hardest to see. A struggling student gives you obvious signals. A "fine" student just hasn't hit the topics that test the foundation yet. Most parents discover the problem only when the syllabus moves on and the questions get harder. This check looks at what the syllabus hasn't tested yet, while there is still time to fix things calmly.
"How long does it take?"
About 10 minutes. Shorter than one homework session, and it tells you more about the foundation than a term of report cards.
"What if the results are fine?"
Then you stop worrying, and that alone is worth 10 minutes. You'll have confirmation instead of assumption, plus a clear view of which areas are strong enough to push further.

One last thing

Every term that passes,
the gaps get harder to close.

Year 9 algebra builds on Year 8. Year 10 exams assume Year 9 was solid. Additional Math expects fluency from day one. The longer a gap goes unnoticed, the more it costs to fix: in time, in stress, and in your child's confidence. Ten minutes tonight could save months next year.
