Course Overview
The AQA GCSE Chemistry course (Specification 8462) provides students with an in-depth understanding of the substances that make up our world and how they interact. Students study ten core topics: Atomic Structure and the Periodic Table, Bonding, Structure and the Properties of Matter, Quantitative Chemistry, Chemical Changes, Energy Changes, The Rate and Extent of Chemical Change, Organic Chemistry, Chemical Analysis, Chemistry of the Atmosphere, and Using Resources.
The course combines theoretical knowledge with hands-on experiments, encouraging students to apply their understanding to real-world scenarios — from industrial processes to environmental issues.
Exams
The course is assessed through two written exam papers, each 1 hour 45 minutes long, contributing 50% to the final grade. The papers include multiple-choice questions, structured questions, and extended responses. A significant portion of marks is linked to required practical activities (20% of the exam marks), where students are expected to demonstrate a strong understanding of experimental methods, data interpretation, and analysis.
Common Challenges
Many students find Quantitative Chemistry challenging, especially when it comes to balancing equations, mole calculations, and percentage yield. Another frequent difficulty lies in applying knowledge of bonding and structure to explain chemical properties.
Students also often struggle with required practicals, particularly in interpreting data and understanding how experiments connect to the theoretical content.
For some, the sheer number of chemical reactions, equations, and definitions to memorise can feel overwhelming.
Our Top Tips for Success
Practise Equations & Calculations: Work through plenty of mole and concentration problems to build fluency.
Use Visual Aids: Diagrams of bonding structures and reaction mechanisms help reinforce understanding.
How Suppree Tuition Supports You
At Suppree Tuition, we simplify the complexities of GCSE Chemistry by teaching students how to understand, apply, and remember the key principles — rather than simply memorising them. We pay particular attention to Quantitative Chemistry and mathematical problem-solving, offering step-by-step guidance and repeated practice with real exam-style questions to ensure students can confidently tackle calculations, from moles to energy changes.
We also dedicate focused sessions to required practicals, explaining the purpose and method of each experiment and practising the data analysis questions that examiners often ask.
Students are taught how to interpret graphs, analyse trends, and evaluate experimental results, which are crucial for high marks.
To improve exam performance, we help students develop set-piece answers for extended questions, using clear, structured responses that hit AQA’s assessment objectives every time. By integrating past papers, personalised feedback, and active recall techniques into every lesson, we not only build subject knowledge but also the exam technique and confidence needed to achieve top grades.
Chemistry at A-Level
For AQA at A-Level schools teach the 7405 specification.

Course Overview
The AQA A-Level Chemistry course (Specification 7405) delves into the principles that explain the composition, structure, and behaviour of matter. Over two years, students study three key areas of chemistry: Physical Chemistry, which explores topics such as atomic structure, bonding, energetics, kinetics, and equilibrium; Inorganic Chemistry, which examines the Periodic Table, transition metals, and redox reactions; and Organic Chemistry, covering alkanes, alkenes, aromatic compounds, polymers, and analytical techniques such as spectroscopy.
The course combines rigorous theoretical content with practical skills, developing students’ ability to analyse data, solve complex problems, and apply chemical principles to real-world contexts — essential preparation for both exams and future scientific study.
Exams
A-Level Chemistry is assessed through three written exams at the end of Year 13, each lasting 2 hours:
-
Physical Chemistry and Inorganic Chemistry
-
Physical Chemistry and Organic Chemistry
-
Practical Skills, Data Analysis, and Synoptic Content
These papers include a mix of short-answer, long-answer, and extended calculation-based questions. Approximately 15% of the marks test practical skills derived from the 12 required experiments completed throughout the course.
Common Challenges
Many students find the mathematical elements of Chemistry challenging, particularly when dealing with calculations involving moles, pH, equilibrium constants, and rate equations. Organic Chemistry is another area students often struggle with, especially when learning complex reaction mechanisms and how to apply them to unfamiliar scenarios.
Another common challenge is answering exam questions concisely while covering the required level of detail for high-mark answers.
Our Top Tips for Success
-
Master Core Maths Skills: Regularly practise calculations such as percentage yield, pH, and rate constants to build accuracy and confidence.
-
Focus on Mechanisms: Break down organic reaction pathways into logical steps and use visual aids to help memorisation.
-
Revise Required Practicals: Know the purpose, methods, and data analysis techniques for all experiments, as these are frequently tested.
How Suppree Tuition Supports You
At Suppree Tuition, we help students tackle the most challenging aspects of A-Level Chemistry by combining targeted content teaching with exam-focused preparation. Our sessions place particular emphasis on maths-heavy topics, such as mole calculations, thermodynamics, and rate equations, by providing step-by-step guidance and repeated practice with real exam-style problems. We also break down complex Organic Chemistry mechanisms into simple, visual explanations, using flow diagrams and practice questions to ensure students can confidently apply their knowledge in any context.
We dedicate focused time to data analysis and required practicals, teaching students how to interpret experimental data, identify errors, and answer related exam questions with precision. A key part of our approach involves building set-piece answers for common extended-response questions, ensuring students know how to structure answers that meet AQA’s assessment objectives and achieve maximum marks.
Our tutors integrate past papers and examiner reports into every lesson, highlighting what examiners look for and how to avoid common mistakes. Through personalised feedback, active recall techniques, and timed practice, we ensure students not only understand the content but also develop the confidence and skills needed to excel in their final exams.
