Learn it.
Then play it.

Hand-written exam questions for both Edexcel A-Level subjects — K-A-A-E chains for Economics B, AO1–AO4 for Business 9BS0 — and an AI marker that returns a real numeric mark with a specific note on what to fix. Anchored in Thames Water, the Sugar Tax, the Greggs case, the 2022 tightening cycle — not the textbook.

Built by a Year 13 student preparing for the same exam.

Opportunity cost

Every choice carries a hidden price: the value of the next-best thing you didn't choose. In an exam, that is not "trade-off". That's the question.

scarcity.

Not poverty, not shortage. The structural condition in which our wants exceed the means available to satisfy them. Every Edexcel A-Level model — economic or business — begins here, and most end by complicating it.

What you actually get

A real graded essay.
Today's queue.

Not a mock-up. The marker writes one specific thing to fix; the dossier surfaces what's due.

"Cost-push pressures from the energy shock raised the SRAS curve, leaving CPI elevated even after demand cooled. Bank Rate at 5.25% cannot reverse the supply shock, but it anchors expectations — preventing a wage-price spiral…"

The method

Why we teach it like this.

phenomenon → model

Most A-Level revision sites give you a wall of bullet points and a button that says "test yourself". The questions that motivated the topic in the first place — why a sugar tax raises £340m but doesn't fix obesity, why Greggs grew slowly while WeWork burned out — arrive, if they arrive at all, as a footnote.

Vofti starts at the other end. Every Economics B and Business 9BS0 sub-chapter opens with a question built around something that actually happened. The diagram arrives only when it earns its way in.
