IB Diploma · Extended Essay & TOK
Which criterion is costing you the marks?
Your school reads the Extended Essay once, late, and there is no resit — the mark is final on a document you can no longer change. Paste a draft and get a mark on every published criterion, plus the one worth an hour before anything else. Your first check is free.
Paste your draft
For the EE this is the research question; for TOK it is the prescribed title. Everything else is judged against it, so it is worth pasting.
✍️ We mark it. We do not write it. You get marks against each criterion, your own sentences quoted back, and what to fix first — plus one rewritten sentence as a demonstration. You will not get paragraphs to paste. The EE and TOK essay are formally assessed coursework: submitting text you did not write is malpractice, and that costs the diploma, not one grade.
🎓 Independent, and not affiliated with anybody. Brain Grain is not affiliated with, endorsed by or connected to the International Baccalaureate Organization or Cambridge Assessment International Education. This applies the published criteria as an independent reader — it is not an IB assessment and not a predicted grade.
