The exam
What the AQA GCSE Biology exam involves
GCSE Biology with AQA (specification 8461) is the single-science Biology GCSE, sat by most students at the Higher tier. It is assessed by two written exam papers covering seven topics, and there is no coursework. This app is built for the Higher tier and covers the whole specification, both papers, so what you revise is the full range of what the exam can ask.
How many papers are in AQA GCSE Biology and how long are they?
There are two papers. Paper 1 and Paper 2 are each 1 hour 45 minutes long and worth 100 marks, so the GCSE is 200 marks in total. Each paper mixes multiple-choice, short-answer, calculation and extended-response questions.
- Paper 1 (84611H): 1h 45m, 100 marks, topics 1 to 4
- Paper 2 (84612H): 1h 45m, 100 marks, topics 5 to 7
- Total: two papers, 200 marks, graded 4 to 9 at Higher tier
What topics are on each paper?
The seven topics are split across the two papers. Paper 1 covers the first four topics and Paper 2 covers the last three. This app organises its questions and flashcards by exactly these topics.
- Paper 1: 1 Cell biology, 2 Organisation, 3 Infection and response, 4 Bioenergetics
- Paper 2: 5 Homeostasis and response, 6 Inheritance, variation and evolution, 7 Ecology
What is the Higher tier in GCSE Biology?
GCSE science is tiered. Higher-tier papers target grades 4 to 9 and include the harder material and the more demanding application and maths questions; Foundation tier targets grades 1 to 5. About 85 percent of separate-science students sit the Higher tier. This app is written for Higher-tier students, so the questions and the calculations match that level.
Where do this app's questions come from?
Every question is original and written to the publicly available AQA GCSE Biology subject content (specification 8461). No AQA exam papers, mark schemes or textbook text is copied. Each question is checked by a second, independent AI model from a different family before it ships, and qualified GCSE teachers from Reagent Academy review the questions after launch. The free sample questions below let you judge the quality before you buy.
Who makes this GCSE Biology revision app?
The app is built by RiverMap Learning in collaboration with Reagent Academy, a UK GCSE tuition provider. RiverMap writes the original questions to the public AQA specification and builds the app; Reagent Academy's GCSE teachers help review the questions for accuracy and specification alignment, and recommend the app to their students.

FAQ
Common questions
Is this the official AQA GCSE Biology app?
No. This is an independent study aid. It is not affiliated with, endorsed by, or sponsored by AQA. It is written to align with the publicly available AQA GCSE Biology specification (8461), but the questions are our own.
Does it cover the whole GCSE or just one paper?
The whole GCSE. It covers all seven topics across both Paper 1 (Cell biology, Organisation, Infection and response, Bioenergetics) and Paper 2 (Homeostasis and response, Inheritance variation and evolution, Ecology), at Higher tier.
Are these real past-paper questions?
No, and that is deliberate. Every question is original and written to the public AQA subject content. We do not copy AQA past papers or mark schemes, both for copyright reasons and so you practise the ideas rather than memorising one paper. Each answer has its own explanation and cites the specification point it tests.
Is the app for Higher tier or Foundation tier?
Higher tier. The questions, the calculations and the maths are pitched at the Higher tier, which targets grades 4 to 9. Combined Science (Trilogy) students sitting Higher Biology will also find most of the content relevant, as the Higher Biology content overlaps.
How many questions and flashcards are included?
There are 534 original multiple-choice questions and 275 flashcards, more than 800 study items in total, spread evenly across all seven topics.
Does the app work offline?
Yes. Everything is stored on your device, so you can revise without an internet connection and there is no login or account to create.
How do I restore my purchase on a new device?
Use the restore purchase option in the app. The one-time purchase is tied to your app store account, so you can restore it on any device using the same account.
How do you check the answers are correct?
Each question is generated and then independently checked by a second AI model from a different family, which confirms the keyed answer is correct and the distractors are wrong, with a human resolving anything flagged. Qualified GCSE teachers from Reagent Academy also review the questions after launch. You can read the full process at rivermaplearning.com/how-we-build-questions.
Who makes this app?
The app is built by RiverMap Learning in collaboration with Reagent Academy, a UK GCSE tuition provider (reagentacademyuk.com). RiverMap writes the original questions and builds the app; Reagent Academy's GCSE teachers help review the questions and recommend it to their students.
