01The diagnosis

The questions don't get harder. They get unfamiliar.

Not because you got worse. Because maths stacks, and one step you never quite got makes everything built on top of it look like something you've never seen. You're not bad at it. You're missing one thing, and it has a name.

Solve 5 − 2x < 11

1Move the 5 to the other side

2Divide both sides by −2

3HereDividing by a negative flips the sign — a rule from Year 8 you saw once. Everything after this looks right, and every mark is gone.

Which is why none of this worked

School	Moved on.
A scan-and-solve app	Gave you an answer. You needed a diagnosis.
A chatbot	It was correct — and useless, because it built on knowledge you don't have.
A tutor	Saw you once a week, for an hour, on their schedule.
A coaching college	Taught ahead, when the hole was behind.

02The evidence

The one you already use is costing you marks.

Roughly a thousand high-school maths students. Half were given an ordinary chatbot to practise with. It went well, right up until the exam.

no change

+48%

on the practice problems, while they still had it

−17%

on the real exam, once it was taken away

The authors call it a crutch. To be clear: the problem isn't the technology. A version with the worked solution and the common mistakes built in removed the harm entirely. Unguarded is the problem.

03The receipt

Same question. One of these answers is wrong.

A flock of 12 600 sheep, males to females 1 : 20. Male weights are normally distributed, μ = 76.2, σ = 6.8. Fifteen males weigh more than x kg. Find x.

A $20/month AI tutor

x = 89.53 kg

Looked z up in a table. There is no z-table in the exam room. Right number, wrong method, no marks.

✓ ACΣD · checked

x = 89.8 kg

The empirical rule. The method the question was written for. 2σ above the mean is the upper 2.5%.

Where the marks go

Reaching for a table or a calculator function. This question is built so z = 2 falls straight out of the rule, and the marker is looking for the rule, not the number.

04The method

Solve it. Prove it. Aim at the break. Hand it back.

01Solve itEvery step, in the method your course actually uses, not the one a textbook from another country uses.

02Prove itChecked against a maths engine, not a second opinion from another model. If it doesn't check out, you don't see it.

03Aim at the breakExplain the one step half the class gets wrong. Skip the ones you had. You can't target where it breaks unless you're certain about the maths, which is why step two comes first.

04Hand it backSame idea, different numbers, and you do it. Watching someone solve it is not the same as being able to.

05Limits

What it won't do.

Not every question checks out

When the checker can't confirm an answer, we show you nothing and say so. We'd rather be unhelpful than wrong.

Maths only, and not all of it

Built for NSW Years 7–12 — strongest on Advanced and Extension 1 today. Extension 2 isn't ready, and we'd rather say that than half-do it.

It won't do the homework for you

Every explanation ends with the question changed and handed back. That's the design, and the study above is why.

Someone else paying?

No appointment to book, no session to cancel, nothing to argue about at the dinner table. It's there at 11pm because it isn't a person. A page written for parents is coming; until then the honest summary is below.
