The synoptic essay at the end of AQA A-Level Biology Paper 3 is a chance to show off your knowledge and secure those crucial marks to push your grade up to an A or even an A*. However, it can feel daunting—especially if you’re unsure how to structure your essay or link your ideas effectively.

What Is the Synoptic Essay?
The synoptic essay is worth 25 marks and is one of the key components of Paper 3 in AQA A-Level Biology. It requires you to:
Draw on knowledge from across the entire specification. That is what synoptic means!
Demonstrate your ability to make connections between different topics.
Use specific examples and keywords.
How to Plan and Structure an A-Grade Essay
A strong essay starts with a solid plan. Here’s how to approach it:
Step 1: Understand the Question
Highlight keywords in the title.
Identify the broad themes the essay is asking you to cover (e.g., transport, communication, or energy transfer).
Step 2: Brainstorm Connections
Create a quick mind map of topics from across the syllabus that relate to the question.
-
Think about how these topics link together. For example:
“Energy transfer” could include photosynthesis, respiration, ecosystems, and muscle contraction.
Step 3: Plan Your Structure
Introduction: Define the key terms in the question and outline what your essay will cover.
-
Main Body: Write 3–5 paragraphs, each focusing on a specific topic. Include:
Factual knowledge (AO1).
Links to other topics (AO2).
Aim to have 10 paragraphs, 5 pairs of links paragraphs
• Paragraph 1 – AO1; description of topic 1
• Paragraph 2 – AO2; how is topic 1 important, point out how it illustrates the theme of the question
• Paragraph 3 – AO1; description of topic 2
• Paragraph 4 – AO2; why is topic 2 important, this part might not as long as the first paragraph on this topic
Repeat for 5 different topics; a topic is a numbered subsection of the specification you should aim to cover 5 in an answer.
Conclusion: Summarise your key points and address the significance of the topic.
Should You Aim for the Last 2 Marks?
In the AQA A-Level Biology synoptic essay, the final 2 marks are awarded for demonstrating knowledge beyond the specification. This means including content that isn’t explicitly taught in your AQA syllabus but is still biologically relevant and well-explained.
Why Chasing These Marks Isn’t Always Worth It
While it might sound appealing to aim for these marks, in reality, it’s not the most efficient use of your time. Here’s why:
Specification Knowledge is Key:
The first 23 marks are entirely based on your ability to cover the topics within the specification and apply them effectively. If your knowledge of the spec is incomplete, chasing extra marks for content outside of it won’t make up for lost marks elsewhere.Limited Return on Investment:
Learning material outside the specification takes time and effort that could be better spent mastering what you know will appear in the exam.Unpredictability:
There’s no guarantee the extra knowledge you learn will fit the essay question on the day.
What’s the Best Strategy?
Focus on Specification Topics:
Your priority should be thoroughly revising the topics listed in your exam specification. Use it as a checklist to ensure you’ve covered every area.
Improve Your Exam Technique:
Marks are often lost not because students don’t know the content, but because they fail to explain it clearly or make connections between topics. Prioritise practising essays to perfect your ability to write concise, well-structured answers.
Save Time:
Rather than hunting for obscure facts, use your time to solidify your understanding of the core material. For example, revising topics like respiration, photosynthesis, and homeostasis in depth will help you write strong essays that hit the higher mark bands.
While those final 2 marks might seem tempting, the smarter strategy is to focus on revising specification content. By doing so, you’ll maximise your chances of scoring highly on the 23 other marks, which are far more predictable and achievable.
Why Keywords Are Essential
A-Level Biology has more new words than A-Level French, so precise terminology is vital. Examiners award marks for:
Word-perfect definitions.
The correct use of technical terms in context.
To help with this, our glossary and keywords flashcards are free on Quizlet and part of our Masterclasses. Use them to ensure you’re confident with the language of biology.
Common Mistakes to Avoid
Waffling: Stick to the point—each paragraph should focus on one idea.
Missing Links: Don’t just list facts; explain how they connect.
Ignoring Keywords: Always define key terms in your introduction and use them throughout.
