year groups
Pearson Edexcel IGCSE Chemistry is organised here into 4 specification units covering 29 named subtopics, studied across Year 8–Year 11. The units are Principles of chemistry, Inorganic chemistry, Physical chemistry and Organic chemistry.
Each subtopic is tagged on the question bank, so you can practise one skill at a time, sit a full Edexcel IGCSE past paper, or build a mixed worksheet from several units at once. Answers are checked against the Pearson Edexcel IGCSE mark scheme, awarding method, accuracy and final-answer marks separately so you can see exactly where marks were lost.
Principles of chemistry is the widest unit on this specification with 10 subtopics, so it is usually the highest-value place to start revision.
Principles of chemistry
- States of matter
- Elements, compounds and mixtures
- Separation techniques
- Atomic structure
- The periodic table
- Chemical formulae, equations and calculations
- Ionic bonding
- Covalent bonding
- Metallic bonding
- Electrolysis
Inorganic chemistry
- Group 1 (alkali metals)
- Group 7 (halogens)
- Gases in the atmosphere
- Reactivity series
- Extraction and uses of metals
- Acids, alkalis and titrations
- Acids, bases and salt preparations
- Chemical tests for ions and gases
Physical chemistry
- Energetics: exothermic and endothermic
- Rates of reaction
- Reversible reactions and equilibria
Organic chemistry
- Introduction to organic chemistry
- Crude oil and fractional distillation
- Alkanes
- Alkenes
- Alcohols
- Carboxylic acids
- Esters
- Synthetic polymers
How to revise Edexcel IGCSE Chemistry
- 1
Diagnose with one mixed set
Start with a mixed set drawn from all 4 units to find where Chemistry marks are actually being lost, rather than revising what already feels comfortable.
- 2
Drill unit by unit
Work through the subtopics in order, from Principles of chemistry to Organic chemistry, doing short focused sets rather than long unfocused sessions.
- 3
Sit a full past paper under timing
Once two or three units are solid, sit a complete Edexcel IGCSE Chemistry paper to timing and mark it against the official mark scheme.
- 4
Re-practise only the dropped marks
Convert every dropped mark into a targeted set on that subtopic, then re-test it a week later to check the fix stuck.

Chemistry — frequently asked questions
Everything students and parents ask about revising Edexcel IGCSE Chemistry.
The fastest route is past-paper-first revision: practise exam-style questions by topic, mark every answer against the real Pearson Edexcel IGCSE mark scheme, then drill the topics where you lose marks. On MathsGradeUp you can do all of this for Chemistry in one place — topic practice, full past papers and instant examiner-grade feedback.
Pearson Edexcel IGCSE Chemistry is mapped to the official specification and covers 4 units, including Principles of chemistry, Inorganic chemistry, Physical chemistry, Organic chemistry. Every unit is broken down into subtopics so you can target exactly what you need to revise.
Yes. You can open full Edexcel IGCSE Chemistry past papers, write directly on them with pen and maths tools, save your work, export a PDF, and submit for examiner-grade marking against the mark scheme.
Yes — our predicted papers for Chemistry are assembled from the topics that recur most in Pearson Edexcel IGCSE exams and the topics you have practised least. They are a revision aid built from the specification, not leaked content.
Each answer is checked against the real Pearson Edexcel IGCSE mark scheme, awarding method, accuracy and final-answer marks the way a real examiner would. You see exactly where marks were earned or dropped, with feedback you can act on.
Chemistry on the Pearson Edexcel IGCSE specification is aimed at Years 8–11. You can filter practice by year group and topic so the questions always match where you are in the course.
Yes. The Chemistry content follows the current Pearson Edexcel IGCSE specification, including all units and subtopics, so what you practise reflects what you will actually be examined on.
Yes — Chemistry practice, past papers and marking are free during our early launch period. Subscription plans may be introduced later, but launch users get full access now.
You do not just get an answer to copy. Chemistry marking guides you with hints, worked steps and mark-scheme-based feedback so you understand the method and pick up the marks yourself next time. Calculation-style questions are tagged so you can practise both structured and extended-response answers.
Yes. Parents and tutors can see completed Chemistry practice, accuracy, weak topics and overall exam readiness, making it easy to support revision and focus on the right areas.
Short, regular sessions beat occasional long ones. Aim for a few focused Chemistry sessions a week, always finishing by marking your work so each session ends with clear next steps. The progress dashboard shows what to revise next.
