Product · Question Bank

An AI-powered question bank, checked by people.

AI drafts each question from real past-paper styles. A person reviews it before any student sees it.

Example step

Every wrong option names a mistake

Solve 2x² − 8x = 0
A
x = 0 or x = 4Correct
B
x = 4 onlyDivided both sides by x and lost x = 0
C
x = −4 or x = 0Sign slip when factorising
D
x = 8Treated it as a linear equation

Every question in three steps

Each question is a path through the DDE Model: Discovery, Declaration, Execution. Each step unlocks the next without giving it away, so a stuck student gets a smaller step, not the answer.

Wrong answers that teach

In a multiple-choice step, the three wrong options are not random. Each one is the result of a specific, nameable mistake, and the review explains it.

Grounded in real exam papers

Questions are modelled on the style of Singapore school past papers and Cambridge examinations, and record the source style they were written from.

Reviewed before use

No AI-drafted question goes into the bank automatically. Our team checks the steps, the answer and every wrong option first.
