What it does
Paste a finished practice essay and its title: see which topic areas it uses, which paragraphs drift from the title and which wordings to fix.
Practice answers to AQA A-level Biology (7402) Paper 3 essay titles, the question worth 25 marks.
Method
- We look for our key terms for 33 areas of the specification. An area counts when your essay names at least two of its terms.
- AQA's June 2025 essay guidance asks for at least four relevant topic areas for the top bands, so the page compares your count with four.
- A paragraph that never uses a word from the title (or a close form of it) is flagged, with its opening quoted.
- Seven wordings AQA mark schemes do not credit, such as "energy is produced" and "the enzyme is killed", are found and quoted with the right wording.
- One rewrite task comes first: add an area if you have fewer than four, then fix a paragraph off the title, then a wording.
