AQA A-Level Chemistry: Syllabus, Past Papers & Resources

If you’re studying towards AQA A-Level Chemistry, you’ve probably already figured out that “knowing the content” and “passing the exam” are two different sports. The specification (code 7405) runs linear exams at the end of Year 13, and past papers from 2017 to 2024 are already sitting on several free repositories online. This guide maps every official resource you need—from the syllabus itself to data sheets, revision notes, and grade boundary trends—so you can stop searching and start revising.

Qualification code: 7405 ·
First teaching: 2015 ·
Structure: Linear ·
Exams: All at end of A-level course ·
Specification source: AQA official site

These four parameters define the AQA A-Level Chemistry 7405 qualification at a glance.

AQA A-Level Chemistry past papers

Past papers are the single most effective revision tool for 7405—working through real exam questions exposes exactly where students lose marks. The good news is that papers from June 2017 through June 2024 are freely available across multiple platforms, and the most recent June 2024 papers include full marking schemes alongside the question papers and data sheet inserts.

Official sources

AQA hosts assessment resources directly at AQA’s chemistry assessment resources page (official publisher of 7405 specification and past papers). This is the primary source for question papers, mark schemes, and examiner reports published after each exam series. Save My Exams aggregates papers from 2017 to 2024 with an interface that lets students filter by year and paper code, making it straightforward to target specific topic areas. Revision Science lists the full 2024 series including Data Sheet Inserts alongside the traditional papers. Physics and Maths Tutor (PMT) goes further by pairing past papers with model answers and, for select papers, video solutions from PMT (established revision platform with worked answers).

Practice tips

Most revision sites recommend starting with topic-specific questions before attempting full papers. Exam Papers Practice aligns its question banks to the 2026 syllabus and includes mark schemes so students can self-mark. The workflow most top performers follow: use revision notes to build understanding, tackle topic questions to lock in content, then test yourself with full past papers under timed conditions. PastPapers.co offers free PDF downloads of papers, mark schemes, and examiner reports in one place—useful if you want everything offline. Kevin the Chemistry Tutor also provides free downloads of past papers and marking schemes.

Bottom line: Students who use PMT for video walkthroughs, Save My Exams for chronological archive browsing, or Exam Papers Practice for 2026-aligned topic questions will find all 2017–2024 papers freely accessible.

AQA A-Level Chemistry syllabus

The AQA A-Level Chemistry syllabus (specification 7405) is a linear qualification, meaning all three exam papers are taken at the end of the two-year course—there’s no AS contribution to the final grade. Students sit three papers: Paper 1 covers Inorganic and Physical Chemistry, Paper 2 covers Organic and Physical Chemistry, and Paper 3 is a synoptic paper that draws across all topics. AQA’s official teaching notes include guidance on new content introduced in the 2015 reform.

Topics at a glance

The specification covers foundational areas—amount of substance, atomic structure, bonding, energetics, kinetics, equilibria—before moving into Organic Chemistry and transition metals. Paper 1 includes Physical Chemistry topics like thermodynamics, kinetics, and equilibria alongside Inorganic Chemistry. Paper 2 tests Organic Chemistry (organic synthesis, mechanistic chemistry, spectroscopy) combined with Physical Chemistry. Paper 3 is a longer paper that can include practical questions, data analysis, and extended response questions drawing on any part of the course. Exam Papers Practice offers topic summaries that mirror the 7405 specification structure, with key definitions and worked examples.

Linear structure

The linear model means there are no module exams during the course—your revision strategy needs to stay current across both years rather than compartmentalising content. This is why most students find that mixing revision notes with past papers is more effective than re-reading textbooks passively. Study Mind provides detailed notes with diagrams covering all key AQA A-Level Chemistry topics, including visual summaries for organic reaction mechanisms. Primrose Kitten’s revision guide breaks down the exam structure paper by paper, helping students understand which topics are weighted more heavily in each exam.

The implication for students is that sustained, interleaved revision throughout Year 12 and Year 13 outperforms last-minute cramming under the linear 7405 structure.

AQA A-Level Chemistry data sheet

The data sheet is an insert provided in the actual exam—it’s not a resource you bring, but information AQA prints inside the question paper booklet. Students who familiarise themselves with it beforehand gain a real advantage, because you don’t waste time hunting for a formula mid-question. It includes relevant equations, standard thermodynamic values, standard electrode potentials, and other constants you’ll need across Physical Chemistry and Inorganic topics.

Key contents

The data sheet covers equations for Physical Chemistry (rate equations, equilibrium constants, Nernst equation), enthalpy definitions, and standard bond enthalpies. For Inorganic Chemistry, it includes standard reduction potentials and trends data. Revision Science lists Data Sheet Inserts alongside each June paper—downloading and printing the insert from the 2024 papers gives you the most current version. Scribd hosts cheat sheets that specifically flag which data sheet values appear in Paper 1 topics like amount of substance, bonding, thermochemistry, kinetics, and equilibria, helping students internalise the sheet rather than just glance at it.

Exam usage

The data sheet is provided in the exam—don’t bring your own copy. However, knowing exactly what’s on it means you can focus on applying values rather than memorising them. Save My Exams notes that some students lose marks unnecessarily because they don’t check the data sheet’s units before starting calculations. The practical tip: use the June 2024 data sheet insert from Revision Science as your reference copy, and annotate the units as you practise past papers.

AQA A-Level Chemistry notes

Revision notes are only useful if they map directly to 7405. Misaligned notes can create false confidence—students who think they’ve covered a topic may discover in the exam that their source covered an older syllabus. All major platforms now market their content as 7405-aligned, but the depth and specificity vary considerably.

Revision sites

Save My Exams is explicit about its alignment: revision notes crafted to match the AQA 7405 syllabus exactly (established revision platform with syllabus-matched content). Exam Papers Practice covers all topics with examples, key definitions, and explanations. Study Mind provides detailed notes with diagrams that some students find easier to process than textbook prose. Thinka.ai offers free study notes for each chapter with worked examples. PastPapers.co provides access to examiner reports alongside notes, which can help students understand exactly what examiners are looking for.

Topic summaries

Physics and Maths Tutor (PMT) provides topic-level past paper filtering for AQA Chemistry, letting students target specific syllabus areas without downloading the full archive. This is particularly useful for Paper 1 Physical Chemistry topics like amount of substance and equilibrium calculations. The trade-off: PMT’s notes are less comprehensive than dedicated revision sites, but they compensate with the linked past paper functionality. Exam Papers Practice recommends pairing their topic summaries with practice questions rather than using notes as passive reading—active recall beats passive re-reading for long-term retention.

AQA A-Level Chemistry grade boundaries

Grade boundaries are set after each exam series based on how students performed nationwide—they aren’t fixed percentages. This means an A grade might require 80 marks in one year and 75 in another, depending on the paper’s difficulty. Grade boundaries are published on the AQA website after results are released for each series, and they shift year to year based on statistical analysis of student performance.

Recent years

The most recent grade boundaries students can reference are from the June 2024 series, available on AQA’s assessment resources page (official exam board). Save My Exams and Revision Science also archive grade boundary data from prior years, making it possible to track trends across multiple series. For the June 2023 series, Save My Exams published the full boundary data alongside past paper downloads. Tracking these trends gives students a realistic target: if the A boundary has hovered between 73–78 marks across the last three series, aiming for 80+ gives a safety margin.

Factors affecting boundaries

Grade boundaries adjust for paper difficulty—a harder paper means lower boundaries to maintain consistent standards. The June 2020 series (pandemic-affected) showed notably different patterns due to calculated grades, making it less useful as a benchmark than 2021–2024 data. For 2026 exams, students should use the most recent available boundaries (2024) as their primary reference, supplemented by the 2022 and 2023 data to understand the range. The implication: don’t assume your practice paper score translates directly to a grade without checking the boundary table for that specific series.

Bottom line: Students who track the 2024 boundaries as their primary reference and review 2021–2023 data to understand the typical range for each grade will have a realistic safety margin—if the A boundary has been 73–78, aiming for 80+ marks positions them above the threshold even if the 2026 paper is slightly harder.
