International A-Level (IAL) - Free Past Papers & Mark Schemes
Access Chemistry past papers covering organic, inorganic, and physical chemistry topics for comprehensive exam preparation. Download free A-Level Chemistry question papers and mark schemes from Edexcel. All papers are available instantly with no sign-up required.
Understanding the exam structure helps you target your revision effectively. Here is a breakdown of each paper:
Covers atomic structure, bonding, introduction to organic chemistry, and alkanes. Foundation paper for AS Chemistry.
Covers energetics, Group 2 and 7 chemistry, kinetics, equilibria, and organic halogen compounds.
Tests experimental skills including titrations, qualitative analysis, and data interpretation.
Advanced kinetics, chemical equilibria, acid-base chemistry, and further organic synthesis including carbonyls and carboxylic acids.
Covers transition metal chemistry, organic nitrogen compounds, and spectroscopic analysis at A2 level.
Chemistry requires a balance between memorising key facts and understanding underlying principles. Organic chemistry, in particular, demands that you learn reaction mechanisms and conditions thoroughly. Create a reaction map linking functional groups to their interconversions, reagents, and conditions. This visual approach helps you plan multi-step organic synthesis routes in exams.
For physical chemistry topics like energetics, kinetics, and equilibria, focus on the mathematical aspects: practise Hess's law calculations, rate equation problems, and equilibrium constant expressions. These topics are heavily calculation-based and regular practice is the most effective revision strategy.
Inorganic chemistry (group chemistry and the transition metals) tends to be more factual. Use concise notes or flashcards for trends, colours, and reactions, and learn the electronic-structure reasoning behind each trend rather than the trend alone.
Units 2, 4 and 5 include extended-writing questions, and Units 2 and 5 end with a contemporary context question. Plan your answer before writing, covering the key scientific points and using correct technical vocabulary throughout.
The following topics are covered across the Chemistry A-Level syllabus:
Six units. The International AS is Units 1 to 3: Unit 1 (Structure, Bonding and Introduction to Organic Chemistry) and Unit 2 (Energetics, Group Chemistry, Halogenoalkanes and Alcohols) are 1 hour 30 minutes and 80 marks, 40% of the AS each, and Unit 3 (Practical Skills in Chemistry I) is 1 hour 20 minutes and 50 marks, 20%. The A2 units are Unit 4 (Rates, Equilibria and Further Organic Chemistry) and Unit 5 (Transition Metals and Organic Nitrogen Chemistry), 1 hour 45 minutes and 90 marks each, and Unit 6 (Practical Skills in Chemistry II), 1 hour 20 minutes and 50 marks. In the full A Level each theory unit is 20% and each practical unit 10%.
Units 3 and 6 are written papers that assess the procedures and techniques developed while studying the theory units, including tests for anions and cations, gases and organic functional groups. Understand how to identify and minimise errors, calculate percentage uncertainties, and interpret results. Past practical papers and examiner reports are the best resources for these questions.
