Mark my answer

Paste (or dictate) an exam-style question and your answer. I'll mark it against your board's style.

How it works

Paste an exam-style question and the answer you wrote, and this free tool marks it the way an examiner would: a score out of the marks available, the marking points you hit, and the ones you missed. AI exam answer marking for CBSE, GCSE, AP, Cambridge and WAEC. It is practice feedback, not an official grade.

  1. Paste the question. Copy it exactly as the paper prints it, command word and marks included. The mark total tells the marker how many separate scoring points to look for.
  2. Add your own answer. Type or dictate what you actually wrote, half-sentences and missing units included. Tidying it up first hides the marks you are really losing.
  3. Add the mark scheme. Optional, but if you have the official scheme from a past paper, paste it and your answer is checked against those exact criteria instead of general ones.
  4. Read what you missed. You get a score out of the marks, a band, the points that earned credit, the points that did not, and a model answer to compare against line by line.

Your exam board changes the answer

CBSE answers are point-marked, so a 3-mark question is checked for three separate scoring points, and numericals are checked for the Given, To find, Formula, Solution, Answer layout. GCSE marking (AQA, Edexcel, OCR) turns on the command word: Describe earns credit for what happens, Explain only for a linked cause-and-effect chain. AP free response is scored against rubric points, so labelling parts (a), (b) and (c) and tying reasoning to a named course concept both matter. Cambridge IGCSE and International A-Level schemes reward exact terminology, so an everyday paraphrase that means the same thing still loses the point. WAEC and WASSCE theory answers are checked as numbered points, each one stated and then explained in a sentence.

Set your exam board — it takes about 30 seconds and every answer after that matches your syllabus.

A 6-mark Explain question, marked

Question pasted in: Explain why the rate of a reaction increases when the temperature rises (6 marks). Answer pasted in: Particles move faster when it is hotter, so they collide more often and the reaction speeds up. It comes back at 2 out of 6. Marking points hit: particles gain kinetic energy; collision frequency increases. Marking points missed: more particles have energy above the activation energy; a greater proportion of collisions are therefore successful; no mention of successful collisions at all. The feedback names the real problem, which is that the answer describes rather than explains, and Explain wants a linked chain. The same student rewriting it with activation energy in the chain reaches 5. The gap was exam technique, not chemistry.

Getting better results

Questions students ask

How accurate is AI exam answer marking?

It is reasonably close on point-marked factual questions where the scoring points are objective, and much shakier on long essays, where two real examiners would disagree with each other anyway. The score is a rough signal; the list of missed marking points is the genuinely useful part. Pasting the official mark scheme from a past paper improves accuracy a lot, because it then checks against real criteria.

Is the score the same as my real grade?

No. A real grade depends on grade boundaries that shift every session, on the whole paper rather than one answer, and on an examiner's judgement about borderline points. The band shown here is an estimate for a single answer in isolation. Use it to find the technique you are missing, not to predict a result. Your teacher's marking on your own board's paper is still the more reliable number.

Do I need the official mark scheme?

No, it works without one and applies typical criteria for your board. But pasting the mark scheme from a past paper makes the marking noticeably fairer, especially in the sciences, where the scheme accepts one specific term and rejects a close synonym that means much the same thing. If you already have the paper open, paste it in.

Which exam boards does it work with?

CBSE, GCSE (AQA, Edexcel and OCR), AP, Cambridge IGCSE and International A-Level, and WAEC or WASSCE. Set your board once and the marking follows that board's conventions: point-marked short answers for CBSE and WAEC, command-word logic for GCSE and Cambridge, rubric points for AP. With no board set it marks to general criteria, which still checks your method but is weaker on wording.

Can it just write the answer for me?

It shows a model answer so you can compare structure, but the tool exists to mark what you wrote, not to hand you something to copy. Submitting AI-written work as coursework counts as malpractice on every board listed here, and it skips the only step that actually raises your marks, which is seeing what your own answer left out. Write first, then mark.

Is it free, and is there a limit?

It is free, with no paid tier and nothing locked behind an account. There is a daily cap on marking runs so the site stays affordable to run, which is enough for a normal revision session rather than an entire past paper in one sitting. Setting your board and year takes a few seconds and makes the marking match your actual paper more closely.
