AI marking that reads maths working, not just answers.

Can AI mark maths working?

Short answer: Yes. Mark My Tests reads each handwritten answer, including the working, and drafts a mark against your mark scheme, so method marks can be awarded where the scheme gives them. Answers it reads with low confidence are flagged for you, and you approve every mark before results go back to students.

How it works

From your test to reviewed results.

  1. 1Credit for the method, as your scheme allowsMaths mark schemes give marks for method as well as accuracy. The AI reads the working and drafts marks the way your scheme sets out, with a short reason for each.
    • Method, accuracy and follow-through marks where your scheme defines them.
    • Notation shown clearly in the review screen.
    • Change any mark before release.
  2. 2Uncertain answers come to you firstCramped working, crossed-out lines and diagrams can be hard to read. Low-confidence answers are flagged, and the original script stays beside the drafted mark.
    • Flagged answers sorted to the top.
    • The student’s page beside each mark.
    • Feedback you can edit.
  3. 3See which questions the class found hardAfter you approve the marks you get question-level results for the class and a PDF for each student.
    • Question-level analysis.
    • Spreadsheet export.
    • Student PDFs.
Example answer

One answer, marked against your scheme.

Each answer is checked point by point against the mark scheme you uploaded, not a generic rubric.

Switch between the AI draft and the answer after your review. Example data.

Q4 · Science · Rates of reaction · 3 marksExample data

Explain why increasing the temperature increases the rate of a reaction.

Student answerthe particles move faster so they collide more often
Mark scheme · Points
✓Particles have more kinetic energy or move faster.
✓More frequent collisions. Allow “collide more often”.
–More collisions have at least the activation energy. Not in this answer.
×Do not accept: “particles collide harder” on its own.

Both markers credited the same two points, so the mark stands.2/3
