- Stoichiometry and the mole (about 5)
- Formulae, equations and ionic equations, Mr, percentage composition, the mole, reacting masses, gas volumes, concentration and titration, empirical formula and percentage yield.
- Electrochemistry and chemical energetics (about 5)
- Electrolysis of molten and aqueous compounds, half-equations, electroplating, fuel cells, exothermic and endothermic reactions, reaction pathway diagrams and bond energies.
- Rates, equilibrium and redox (about 4)
- Factors affecting rate and collision theory, catalysts, reversible reactions, equilibrium, the Haber and Contact processes, oxidation, reduction and oxidising agents.
- Acids, bases, salts and analysis (about 5)
- pH and indicators, strong and weak acids, reactions of acids, types of oxide, preparing soluble and insoluble salts, and tests for ions and gases.
- Periodic Table, metals and environment (about 5)
- Group I, Group VII, transition elements and noble gases, the reactivity series, extraction of iron and aluminium, alloys, rusting, air and water, pollution and climate change.
- Organic chemistry (about 5)
- Homologous series, alkanes, alkenes, alcohols, carboxylic acids and esters, fuels and cracking, isomers, addition and condensation polymers.
How to use these mocks before the exam
- Take each mock in one sitting, timed, with only the equipment allowed in the exam.
- Do calculations on paper and check the units before choosing an answer.
- Cover the options, work out your own answer first, then find it in the list.
- Read every explanation for the questions you got wrong and redo them a day later.
- Watch for NOT, LEAST and MOST in the question. They decide which option is correct.
- Learn the colours in the tests for ions and gases: they come up in almost every paper.
Frequently asked questions
When is IGCSE Chemistry 0620 Paper 1 or Paper 2 in November 2026?
In India and the rest of Cambridge zone 4, Paper 1 (0620/12) and Paper 2 (0620/22) are on the afternoon of Thursday 12 November 2026. Other Cambridge administrative zones can sit a different variant on a different day, so always check the timetable and start time with your exam centre.
Are these mock tests the same format as the real paper?
Each mock has 40 four-option multiple-choice questions in 45 minutes, the same as the real paper, in a similar topic balance. The questions are written by our teachers, not copied from past papers, so you can use them alongside past papers without repeating questions.
Is there negative marking?
No. Each correct answer scores one mark and wrong answers lose nothing, so answer every question.
How is my mock marked?
As soon as you submit you see your score, a topic-by-topic breakdown and an explanation for every question. The result is also emailed to you.
Are the mock tests free?
Yes. You only need to enter your name, email, phone number, school and grade so that we can send you your result.
