AI marking for maths, one step at a time.
Most answer checkers tell you whether the final number is right. Method marks the whole solution the way a mark scheme does, so a wrong answer can still earn most of its marks, and a right answer with gaps in the working can still lose some.
Three kinds of mark, on every line.
Maths mark schemes split credit into method, accuracy and independent marks. Method awards them the same way. The full shorthand, including ft, cao and AG, is in the mark scheme guide.
Method marks
For choosing and applying a valid method. A slip in the arithmetic doesn't cost you the M mark.
Accuracy marks
For correct working and answers. They depend on the method mark before them.
Independent marks
For a correct result or statement that stands on its own, whatever the method.
A wrong answer that still scores.
Here's a short question, marked the way Method marks it. The factorisation is right, but one root has the wrong sign.
A right-or-wrong checker would give this nothing. On a mark scheme it keeps the method mark, and the note tells you exactly which line to fix.
- (3x − 2)(x − 3) = 0M1Correct factorisation: the method mark is earned.
- x = −⅔ or x = 3A03x − 2 = 0 gives x = ⅔, not −⅔. One root is wrong, so the accuracy mark is lost.
How a mark is decided.
Read
Your handwriting is read line by line, including crossed-out work and untidy notation.
Match
The question is detected and matched to the right paper, question and mark scheme.
Mark
Each step is marked against examiner-style criteria: M, A and B marks, follow-through where the scheme allows it, and a note on every lost mark.
Audit
A second, independent pass checks the marking before you see it. Where a step is borderline, Method says so instead of presenting a guess as fact.
Marking you can argue with.
Think Method has misread a step? Tap Dispute on that mark. The step is checked again against the mark scheme, and if you were right, the mark changes. The scheme is the reference, not the AI.
Half the value is in the disputes you lose: seeing the mark scheme next to your own line is often the fastest way to learn what an examiner needs to see.
What AI marking can't do.
- It's practice, not a grade
- Marks and estimated grades are indicative. Grade boundaries change every session, and only the exam board can award an official result.
- It can be wrong on a borderline step
- That's why every mark can be disputed, and why borderline marks are flagged rather than hidden.
- It won't guess at what it can't read
- If a step is genuinely unreadable, you're told which one, instead of it being marked from a guess.
- Generated questions aren't board papers
- Questions Method writes for extra practice come with an AI mark scheme in the board's style. They're practice material, not official exam-board content.
Your working stays yours.
- You keep ownership of everything you write or scan.
- Your working is processed to mark it and show it back to you, and to track your progress.
- It is never sold, never used for ads, and never shared with your school or an exam board without your say-so.
- Anonymised working may be used to improve marking accuracy, and you can opt out in settings.
- Delete your account and your working, marks and history go with it.
