The exam
What the AQA GCSE Chemistry exam involves
GCSE Chemistry with AQA (specification 8462) is the single-science Chemistry GCSE, sat by most separate-science students at the Higher tier. It is assessed by two written exam papers covering ten topics, and there is no coursework. This app is built for the Higher tier and covers the whole specification, both papers, including all the chemistry-only content, so what you revise is the full range of what the exam can ask.
How many papers are in AQA GCSE Chemistry 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 (8462/1H): 1h 45m, 100 marks, topics 1 to 5
- Paper 2 (8462/2H): 1h 45m, 100 marks, topics 6 to 10
- Total: two papers, 200 marks, graded 4 to 9 at Higher tier
What topics are on each paper?
The ten topics are split across the two papers. Paper 1 covers the first five topics and Paper 2 covers the last five, though Paper 2 can still draw on the fundamentals of atomic structure, bonding and quantitative chemistry. This app organises its questions and flashcards by exactly these topics.
- Paper 1: 1 Atomic structure and the periodic table, 2 Bonding structure and properties, 3 Quantitative chemistry, 4 Chemical changes, 5 Energy changes
- Paper 2: 6 The rate and extent of chemical change, 7 Organic chemistry, 8 Chemical analysis, 9 Chemistry of the atmosphere, 10 Using resources
What is the Higher tier in GCSE Chemistry?
GCSE science is tiered. Higher-tier papers target grades 4 to 9 and include the harder material and the more demanding maths, such as moles, concentrations and atom economy; 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, and Higher-only content is tagged to its specification point.
Where do this app's questions come from?
Every question is original and written to the publicly available AQA GCSE Chemistry subject content (specification 8462). No AQA exam papers, mark schemes or textbook text is copied. Every calculation is recomputed and every answer is independently checked by a second AI model from a different family before the app ships, and qualified GCSE teachers from Reagent Academy review the questions. The free sample questions below let you judge the quality before you buy.
Who makes this GCSE Chemistry 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.

Content audit trail
- 2026-07-22 Initial build: 672 original questions and 301 flashcards covering all ten topics across both papers, written to the public AQA 8462 Higher subject content, with a one-page topic note per topic.
- 2026-07-22 QA: every calculation was recomputed and every keyed answer re-checked against the AQA subject content in an independent pass before release.
- 2026-07-22 Independent cross-model review: a second AI model from a different family checked every question, flashcard, topic note and diagram against the AQA 8462 subject content; a small number of off-spec items were removed and the flagged answers and figures were corrected.
FAQ
Common questions
Is this the official AQA GCSE Chemistry 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 Chemistry specification (8462), but the questions are our own.
Does it cover the whole GCSE or just one paper?
The whole GCSE. It covers all ten topics across both Paper 1 (Atomic structure, Bonding, Quantitative chemistry, Chemical changes, Energy changes) and Paper 2 (Rate and extent of chemical change, Organic chemistry, Chemical analysis, Chemistry of the atmosphere, Using resources), at Higher tier, including the chemistry-only content of the separate GCSE.
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 Chemistry will also find most of the content relevant, although the chemistry-only topics go beyond Combined Science.
How many questions and flashcards are included?
There are 672 original multiple-choice questions and 301 flashcards, close to a thousand study items in total, spread across all ten 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?
Every question is generated to the public specification, then independently re-checked before release: a second AI model from a different family verifies every keyed answer against the AQA subject content, recomputes every calculation from scratch, and checks the distractors so that none is accidentally true. Anything off-spec is removed. Qualified GCSE teachers from Reagent Academy also review the questions. 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.
