How to answer A-level Biology essay questions
The Synoptic essay question on paper 3 of the AQA A-level biology course carries 25 marks, so doing well can make a big difference to your overall grade. The essay encourages you to think across different topics (some call this “synoptic” or “holistic” thinking). This is also valuable for other areas of the exams, particularly the application questions .
Here are a few tips for tackling your A-level biology essay: (As an example, let’s use the title “ The importance of movement in cells and tissues ”)
Think broadly…
Essay titles are deliberately vague to give you the chance to show your knowledge in a variety of topics. To help you to choose what’s most relevant, look out for subjective words like “movement” and “cells”. Think of the possible alternatives. “Cells”, for example, hints that you could discuss plants, animals, single-celled organisms etc. in your essay. “Movement” could mean short distances (across a membrane) or much further (circulation or mass flow) or even the whole tissue moving (phototropism).
Visualize and catastrophize!
If you can’t think of enough topics for an “importance” essay, flip the question around – what would happen if movement in cells suddenly ground to a halt? Or if ATP suddenly vanished, or our cells were robbed of their ions? Sometimes catastrophizing in this way frees up thoughts, and helps you see what is really important. Another way is to picture every diagram in your notes or textbook that features the thing-that’s-important-in-the-question. If it’s in a diagram, it could go in your essay.
Pick your strongest topics
It’s possible to drop marks on the essay for scientific errors. With that in mind, even if you have lots of ideas for things to include, always pick the topics you can write confidently about. For bonus marks, try to order them in a way that “flows” like a story. Take care to use A-level (and not GCSE) language too.
Keep an eye on the question
While you’re writing, keep asking yourself “Where am I placing the emphasis?”. If the essay is about movement, perhaps you don’t need a whole page about nervous responses, only the bits where movement is involved – sodium ions flowing through channels, waves of depolarisation etc. Movement is the focus of the essay, after all, not neurons. Always ask yourself “Does this sentence fit with the title of the essay?”
Use outside knowledge
The top marks for the essay are reserved for displaying “evidence of reading beyond specification requirements”. Often you can drop recent scientific research or news into your writing – how vaccines tackle COVID might work in an essay about viruses, for example. I often encourage students to have a quick look at the news pages of New Scientist pages (eg https://www.newscientist.com/subject/health/ ) before paper 3 for inspiration – you don’t need to spend ages doing this, just long enough to have one or two ideas up your sleeve…
Good luck with your essay!

Biology is detailed and comprehensive A-level content, uses appropriate terminology, and is very well written and always clearly explained. No significant errors or irrelevant material. For top marks in the band, the answer shows evidence of reading beyond specification requirements. 16-20. Relational.
Advice for the essay. The levels scheme states that more than two A-level topics need to be addressed to get higher than 10 marks. A minimum of four topics is required to get higher than 15 marks. A topic area is a numbered sub-section in the specification. For example, for the 2017 'diffusion' essay, gas exchange (3.3.2) was a topic area.
Appropriate terminology was often poorly used or absent. For example, many students wrote about 'signals' and 'messages' rather than impulses/action potentials. The use of 'levels' and 'amounts' for concentration was also very common. The essay is supposed to be written using appropriate terminology, at a level to be expected ...

A tutor can help you write the biology AQA essay by giving guidance and importantly, marking several essays or essay plans and giving critical feedback before Paper 3. How to write a biology essay. A successful essay pulls together topics from different areas of the specification, and uses them to illustrate an underlying theme.
Focusing on the essay performance on the 7402 biology specification only, we can see how the 2017-2019 essays have performed in isolation in Figure 2. The 7402 essay has shown performance that skews slightly to the higher end of the mark scale, which is understandable given the mean mark sits just above 50%.
