Mistake notebook

Every mark you lose in AI marking, and every practice answer you mark as wrong, is saved here automatically. Each entry shows the line you wrote, what the mark scheme needed and, where examiners have flagged the same slip, a tip. Press Retry a similar question to try a fresh question on the same topic: get it fully right and the mistake is marked fixed, then it comes back once after 7 days to check it has stuck. Only you can see your notebook.
