The artefact

Not a chat transcript. Your script, with ink in the margins.

Green stamps when the method earns. Crimson when it doesn't. The same object you would get back from a real examiner — except it lands in about a minute.

How marking works

Ink lands. Truth shows.

Not a chatbot guessing. The real scheme for that paper — B1, M1, A1 — stamped onto your lines, so the next attempt hits what this one missed.

1.

Put the working on the desk

Type it, snap the page, or drop a PDF. Name the paper — we pull the scheme that examiner used.

Typed · Q7(b) working9702_s23_qp_22.pdf
2.

Every mark earns a stamp

Line by line against the scheme — green when it lands, crimson when it slips, codes in the margin like the real hall.

C1 ✓ ω = 2π/TM0 ✗ wrong relationB1 ✓ sketch correct
3.

Chase the leak, not the chapter

Dropped marks open the exact syllabus point — and on Max, the Vault rebuilds a desk and Cinema beat around it.

Why a student built MarkScheme

“I built this because I couldn't tell whether my working would actually score. Past papers without the examiner's eye are half the loop — this closes it.”
