How we know what we say — and how we check it

Grounded on, not trained on

Every answer Gradora publishes is grounded onthe official source material for that exam: the exam board's published specification, its mark-scheme conventions, and examiner reports. We use those sources as reference inputto build an original, plain-English explanation of how marks are earned. We do not reproduce mark-scheme text, and we are not “trained on” board prose — the wording you read is Gradora's own, written to make the marking transparent.

What our answers are built from

• Published specifications for AQA, Edexcel, OCR, WJEC-Eduqas, so each page is aligned to the right board at the right level (GCSE or A-Level).
• Mark-scheme conventions — the method (M), accuracy (A), independent (B) and explanation (E) marks, and the AO1/AO2/AO3 assessment objectives — decoded into student-friendly language.
• Examiner reports, which tell us the mistakes students most commonly make, so “common mistakes” sections reflect what markers actually see.

We reference exam boards factually, to align our content to their published standards. No endorsement by any board is implied.

How we verify it

A wrong answer is worse than no answer — especially for a product whose whole job is marking. So every answer passes through Gradora's QA process before it is published: it is checked back against the mark scheme it claims to follow, and an independent verification step confirms the working and the marks before the page can go live. Answers that don't pass are held for human review, not published.

Kept current

Specifications and mark schemes change. Every page carries a visible “Last updated” date, and we review content on a regular cycle so what you read reflects the current standards.

What we don't claim

We don't promise grades, and we won't. We can't honestly know what any one student will achieve, so we don't claim it. What we offer is clarity: a clear, verifiable view of where the marks go, and a specific way to pick them back up.
