AQA A-Level Chemistry (7405) is assessed by three 2-hour papers: Papers 1 and 2 (105 marks each, 35%) and Paper 3 (90 marks, 30%), which includes multiple choice and practical skills. Our AQA A-Level Chemistry course follows the 7405 specification across physical, inorganic and organic chemistry: atomic structure, amount of substance, bonding, energetics, kinetics, equilibria, redox, the periodic table, transition metals, organic mechanisms, synthesis and spectroscopy. You prepare for all three 2-hour papers and the required practicals. Lessons are live and one-to-one with a verified subject tutor, who sets exam-style questions, marks them against the mark scheme and plans revision around your weakest topics. Suitable for Year 12 and Year 13 students, private candidates and resits.

Course structure
In short: this course gives one-to-one online tutoring for AQA A-level Chemistry (7405). A verified chemistry tutor teaches physical, inorganic and organic chemistry, the required practicals and multi-step calculations, using AQA past papers and mark schemes.
AQA A-Level Chemistry (7405) is a linear A-Level taken over two years, covering physical, inorganic and organic chemistry. It is assessed by three 2-hour written exams at the end of the course, graded A* to E, with a separately reported practical endorsement.
This course covers the full specification one to one with a verified chemistry tutor.
Official specification: AQA A-level Chemistry 7405.

AQA A-level Chemistry is assessed by three written papers, each lasting 2 hours. Papers 1 and 2 are worth 105 marks and 35% each; Paper 3 is worth 90 marks and 30% and includes multiple choice and practical-based questions.
| Paper | Content | Marks | Weighting | Question types |
|---|---|---|---|---|
| Paper 1 | Relevant physical chemistry, inorganic chemistry and practical skills | 105 | 35% | Short and long answer |
| Paper 2 | Relevant physical chemistry, organic chemistry and practical skills | 105 | 35% | Short and long answer |
| Paper 3 | Any content and any practical skills | 90 | 30% | 40 marks practical techniques and data analysis; 20 marks across the specification; 30 marks multiple choice |
Across the three papers, AQA weights the assessment objectives at about 30% knowledge and understanding (AO1), 45% applying it (AO2) and 25% analysing, interpreting and evaluating information and evidence (AO3). Applying knowledge to unfamiliar reactions and data carries the most weight.
| Objective | What it tests | Overall weighting |
|---|---|---|
| AO1 | Knowledge and understanding of scientific ideas, processes and techniques | 30% |
| AO2 | Applying knowledge and understanding | 45% |
| AO3 | Analysing, interpreting and evaluating information, ideas and evidence | 25% |
| Area | Key content |
|---|---|
| Physical chemistry | Atomic structure, amount of substance, bonding, energetics, kinetics, equilibria and Kc, redox, thermodynamics, rate equations, Kp, electrode potentials, acids and bases |
| Inorganic chemistry | Periodicity, Group 2, the halogens, Period 3 elements and oxides, transition metals, reactions of ions in aqueous solution |
| Organic chemistry | Alkanes, halogenoalkanes, alkenes, alcohols, organic analysis, isomerism, carbonyl compounds, aromatic chemistry, amines, polymers, amino acids and DNA, organic synthesis, NMR and chromatography |
Calculations carry a large share of marks across all three papers.
Tutors drill every mechanism, from free-radical substitution to nucleophilic addition-elimination, with precise curly arrows, and go through all 12 required practicals with their methods, apparatus and analysis.
Here is a typical pH question: calculate the pH of 0.020 mol dm⁻³ hydrochloric acid, a strong monoprotic acid.
| Step | Working |
|---|---|
| Strong acid fully dissociates | [H⁺] = 0.020 mol dm⁻³ |
| pH formula | pH = −log₁₀[H⁺] |
| Calculate | −log₁₀(0.020) = 1.70 |
| Answer | pH = 1.70 (two decimal places) |
A-level chemistry students most often lose marks on calculation steps without units, curly arrows drawn from the wrong place, imprecise explanations of trends, weak practical answers and not giving pH to two decimal places.
| Mark-loser | What to do instead |
|---|---|
| Missing units and steps | Show each step with units |
| Curly arrows misplaced | Start at a lone pair or bond; end at an atom or bond |
| Vague trend explanations | Explain in terms of structure and bonding |
| Weak practical answers | Name the technique, variables and improvements |
| pH to wrong precision | Give pH to two decimal places |
Lessons are live and one to one on video with a shared whiteboard. Your tutor uses AQA past papers and mark schemes. See also AQA A-Level Biology, Edexcel A-Level Chemistry and our Chemistry subject page.
An A level chemistry tutor online gives you live 1-to-1 lessons on the AQA 7405 topics, with step-by-step calculations, mechanisms and the required practicals.
This course suits Year 12 and Year 13 students taking AQA A-Level Chemistry, and resit students.
Prerequisites: GCSE Chemistry or Combined Science, basic algebra and balancing equations.
Course length: 50 one-hour lessons across 6 modules.
| Stage | Topics | What you can do afterwards |
|---|---|---|
| 1 | Physical chemistry | Solve mole, energy and equilibrium problems |
| 2 | Inorganic chemistry; organic chemistry | Explain periodic trends and draw basic mechanisms |
| 3 | Advanced physical chemistry | Solve rates, equilibrium and electrode problems |
| 4 | Advanced inorganic and organic chemistry | Explain transition metals and plan organic synthesis |

The code is 7405 (7404 for AS).
Three 2-hour papers: Paper 1 (105 marks), Paper 2 (105 marks) and Paper 3 (90 marks).
Yes. Paper 3 includes 30 marks of multiple-choice questions.
Twelve required practicals for the A-Level.
A teacher-assessed endorsement reported separately as Pass or Not classified.
Many students find organic synthesis, electrode potentials and equilibrium calculations the hardest.
Master calculations and mechanisms, learn required practicals thoroughly and practise past papers with mark schemes.
Yes. Tutors use AQA past papers and mark schemes.
The price depends on the tutor and session length. You see the hourly rate before booking, with no subscription.
Yes. Tutors focus on the topics that will lift your grade most.
Each of the three papers is 2 hours.
Split revision across physical, inorganic and organic chemistry, then practise past-paper questions and mark them with AQA mark schemes. Give extra time to calculations, reaction mechanisms and the required practicals, which Paper 3 tests directly. Your tutor builds a weekly plan around your weakest topics and exam dates so nothing is left to the last month.
Yes. AQA provides a data booklet in A-Level Chemistry exams, including the periodic table, infrared and NMR data. It does not give you reaction mechanisms or equations, so you still need to learn those. Your tutor shows you how to use the data booklet quickly and accurately under exam conditions.
Yes. Lessons are online, so you can book times that suit your time zone and school week.
Any content: 40 marks on practical techniques and data analysis, 20 marks across the specification and 30 marks of multiple choice.
For a strong monoprotic acid, [H⁺] equals the acid concentration, and pH = −log₁₀[H⁺]. For 0.020 mol dm⁻³, pH = 1.70.
AQA publishes grade boundaries for AQA A-Level Chemistry after each exam series, and they change from year to year with paper difficulty. They show the raw marks needed for each grade. Your tutor marks full past papers and compares your scores with recent boundaries to estimate your grade and target the topics that matter most.
Paper 2 covers organic chemistry with relevant physical chemistry; Paper 3 can test any content.
Learn each mechanism by type, practise drawing arrows correctly and apply them to unfamiliar molecules.
Weekly lessons suit most students; add extra sessions before mocks and final exams.
Yes. You can learn with a 1-to-1 A level chemistry tutor online through live video lessons. Your tutor works through calculations step by step, explains mechanisms, covers the required practicals and uses past papers to find and fix your weak areas before the exams.
