AQA GCSE Biology (specification 8461) is assessed by two written papers rather than a single timed test, and unlike many professional exams, it has no pre-set pass mark. Here is what the real exam looks like, and how a practice app can still give you something to aim for.
How many questions are on the GCSE Biology exam?
The real exam is not structured as a fixed count of questions. Paper 1 and Paper 2 are each 100 marks, and each paper mixes multiple-choice, short-answer, calculation and extended-response items rather than a uniform list of single-mark questions. That is different from a professional licensing test with, say, 45 flat multiple-choice items: the number of discrete questions on an AQA science paper depends on how many marks each item is worth.
Is there a fixed pass mark for GCSE Biology?
No, and this is the detail most search results get wrong. GCSEs do not have a pass mark set in advance. AQA publishes grade boundaries after each exam series, once the papers have been sat and marked, and those boundaries can move slightly from year to year depending on how the cohort performs. There is no number you can memorise in June that guarantees a grade in August.
Because there is no fixed pass mark, the useful target while you revise is topic by topic rather than one overall score: work through each topic’s practice questions until you answer them correctly, and read the explanation on every one you miss.
How long is the AQA GCSE Biology exam?
There are two papers, each 1 hour 45 minutes long and worth 100 marks, for 200 marks across the whole GCSE:
- Paper 1 (84611H): 1h 45m, 100 marks
- Paper 2 (84612H): 1h 45m, 100 marks
Both papers are Higher tier, and there is no coursework component in the current specification.
What topics are split across the two papers?
The specification groups seven topics across the two papers:
- Paper 1 covers Cell biology, Organisation, Infection and response, and Bioenergetics.
- Paper 2 covers Homeostasis and response, Inheritance, variation and evolution, and Ecology.
Cell biology spans cell structure, microscopy, mitosis, stem cells and transport across cell membranes. Organisation moves from cells to tissues, organs and systems, including the digestive system, the heart and non-communicable disease. Infection and response covers pathogens, vaccination and drug development. Bioenergetics deals with photosynthesis and respiration. Homeostasis and response covers the nervous and endocrine systems and control of internal conditions. Inheritance, variation and evolution covers genetics, natural selection and classification. Ecology covers ecosystems, the carbon and water cycles, biodiversity and food security.
What is the Higher tier in GCSE Biology?
GCSE science is split into Foundation and Higher tiers, and both papers here are Higher tier, which targets grades 4 to 9 and carries the harder application and maths-based questions. Foundation tier covers the lower grade range with different papers.
How can I practice for the exam if there is no pass mark to aim for?
Since AQA does not release a practice pass mark, the most useful thing a revision tool can do is cover the full breadth of both papers and show you, topic by topic, where you are still losing marks. The RiverMap Learning AQA GCSE Biology app has a one-page note for each of the seven topics, 534 original questions and 359 flashcards across all seven, and quizzes of 10, 20 or 30 questions from any mix of topics. Every question is original and written to the public AQA subject content, never copied from a real paper, and every answer comes with a plain-English explanation of the underlying biology.
