Quick answer
AI marking is useful for Cambridge and IB revision only when it uses real mark scheme / markband language — not generic essay grades. MarkScheme ([markscheme.app/mark](/mark)) marks uploaded handwriting against official Cambridge schemes (B1/M1/A1, bands, MCQ) and IB criteria. Use it as a second marker after strict self-marking; do not trust ChatGPT alone for session-specific schemes.
“AI marked my essay 18/20” is only useful if the AI used Cambridge band language, not a generic rubric from the internet. Students should treat AI marking like a second marker — not a replacement for the specification.

- Scores with no tie to syllabus wording
- Ignoring method marks in maths

- No visibility of handwriting — blurry uploads create fantasy feedback.
A healthy workflow
