As of 13 August 2026, AI can mark your GCSE practice answers.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open the question paper and official mark scheme for the same GCSE subject, exam board and paper, and confirm that they match.
   2. Copy the full question, its maximum mark and the relevant mark-scheme or examiner-guidance section into a document.
   3. Type your complete answer exactly as written, or take a clear image showing every line and any diagrams, labels or calculations.
   4. Paste the question, mark scheme and answer into ChatGPT, Claude or Gemini with the supplied prompt, filling in the bracketed details.
   5. Compare the model's awarded points and explanations with each relevant line of the mark scheme, and correct any decision that relies on information the mark scheme does not support.
   6. Redo the question without looking at the feedback, then use the original mark scheme and your checked feedback to record the missed points in your revision notes.

   Prompt

   Act as an indicative GCSE practice marker, not an official examiner. Mark the answer below using only the question, context and mark scheme I provide. Do not invent marking criteria or award marks for points that are not supported by the mark scheme.
   
   Subject: [subject]
   Exam board: [exam board]
   Qualification and paper: [GCSE qualification and paper]
   Question and command word: [paste the full question]
   Maximum mark: [number]
   Mark scheme or examiner guidance: [paste the relevant material]
   My answer: [paste the complete answer]
   
   Return:
   1. An indicative mark out of the stated maximum.
   2. A point-by-point table showing which mark-scheme points I earned, partly earned or missed, with a short quotation or reference to my answer for each decision.
   3. Separate comments on knowledge, use of evidence, accuracy, structure and the question's command word where relevant.
   4. The smallest changes that would improve the answer, without rewriting it for me.
   5. A short model outline, not a full answer, showing what a stronger response would need to cover.
   
   If the mark scheme is missing, unclear or does not match the question, say that you cannot give a dependable mark and give feedback only. If the answer is handwritten or the image is hard to read, list the words you cannot read before marking. State clearly where examiner judgement could change the mark.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.
