Edexcel GCSE Chemistry (1CH0) is assessed by two 1 hour 45 minute papers, each worth 100 marks, at Foundation or Higher tier, with eight core practicals tested in the exams. Our Edexcel GCSE Chemistry course follows the 1CH0 specification and covers key concepts in chemistry, states of matter, chemical changes, extracting metals and equilibria, groups in the periodic table, rates of reaction, fuels and earth science, and separate chemistry topics. You prepare for both 1 hour 45 minute papers, including calculations and the core practicals. Lessons are live and one-to-one with a verified subject tutor, who works through exam-style questions with you, marks your answers against the Edexcel mark scheme and shows you where marks are won and lost. Suitable for foundation and higher tier students in Year 10 and Year 11, and for resits.

Course structure
In short: this course gives one-to-one online tutoring for Pearson Edexcel GCSE Chemistry (1CH0) at Foundation and Higher tier. A verified chemistry tutor teaches every topic, the core practicals and exam technique, using Edexcel past papers and mark schemes.
Edexcel GCSE Chemistry (1CH0) is the separate-science GCSE in chemistry from Pearson Edexcel, usually taken at the end of Year 11. It is graded 9 to 1 and offered at Foundation tier (grades 5 to 1) and Higher tier (grades 9 to 4).
This course covers the full 1CH0 specification one to one with a verified chemistry tutor, so lessons focus on the topics and question types that cost you marks.
Official specification: Pearson Edexcel GCSE Chemistry (1CH0).
For wider support, see our chemistry tutoring page, or the AQA GCSE Chemistry course if your school follows AQA.
Pearson Edexcel GCSE Chemistry (1CH0) is assessed by two written papers, each lasting 1 hour 45 minutes, worth 100 marks and 50% of the GCSE. Both papers are taken at the same tier: Foundation (grades 1 to 5) or Higher (grades 4 to 9).
| Paper | Content | Time | Marks | Weighting |
|---|---|---|---|---|
| Paper 1 | Topics 1–5: key concepts in chemistry; states of matter and mixtures; chemical changes; extracting metals and equilibria; separate chemistry 1 | 1 hour 45 minutes | 100 | 50% |
| Paper 2 | Topic 1 plus Topics 6–9: groups in the periodic table; rates of reaction and energy changes; fuels and Earth science; separate chemistry 2 | 1 hour 45 minutes | 100 | 50% |
The assessment objectives are weighted 40% knowledge and understanding (AO1), 40% application (AO2) and 20% analysis, interpretation and evaluation (AO3), each within three percentage points. Each paper carries roughly 20, 20 and 10 percentage points of these.
| Objective | What it tests | Weighting |
|---|---|---|
| AO1 | Knowledge and understanding of scientific ideas and techniques | 40% |
| AO2 | Applying knowledge and understanding | 40% |
| AO3 | Analysing, interpreting and evaluating information and evidence | 20% |
Tutors cover each core practical's method, variables, risks and exam questions, including chromatography, investigating pH, electrolysis, preparing a salt, acid-alkali titration, rates of reaction, temperature changes, and identifying ions.
Here is a typical calculation: what mass of magnesium oxide forms when 4.8 g of magnesium burns completely? (Mg = 24, O = 16.)
| Step | Working |
|---|---|
| Equation | 2Mg + O₂ → 2MgO |
| Moles of Mg | 4.8 ÷ 24 = 0.20 mol |
| Moles of MgO | 0.20 mol (2 : 2 ratio) |
| Mass of MgO | 0.20 × 40 = 8.0 g |
Students most often lose chemistry marks on unbalanced equations, calculations without units, vague extended answers and imprecise practical answers.
| Mark-loser | What to do instead |
|---|---|
| Unbalanced equations | Balance and add state symbols where asked |
| Missing calculation steps | Show each step with units |
| Vague extended answers | Use a logical sequence and key terms |
| Bonding confused | Link structure to properties |
| Weak practical answers | Name variables, equipment and risks |
On Edexcel Combined Science (1SC0), chemistry is a subset of the same topics in two 1 hour 10 minute chemistry papers. Tell your tutor which course and tier you're on.
Lessons are live and one to one on video with a shared whiteboard. Your tutor starts with a quick diagnostic, plans lessons around your weakest topics, sets exam-style questions between sessions and marks them against the Edexcel mark scheme. Suitable for Year 10 and 11 students, resit candidates and home-schooled students. For specific questions, try homework help or see our Chemistry subject page.
GCSE Chemistry Edexcel past papers show you how 1CH0 is examined, and this course pairs them with live 1-to-1 lessons on every topic, the core practicals and chemistry calculations.
This course suits Year 10 and Year 11 students taking separate GCSE Chemistry at Foundation or Higher tier.
Prerequisites: basic science, maths and atoms, elements and compounds.
Course length: 40 one-hour lessons across 9 modules.
| Stage | Topics | What you can do afterwards |
|---|---|---|
| 1 | Atomic structure; states of matter and mixtures | Explain atoms and separate mixtures |
| 2 | Chemical changes; extracting metals and equilibria | Explain acids, electrolysis and equilibria |
| 3 | Separate chemistry 1; groups in the periodic table | Solve calculations and predict group behaviour |
| 4 | Rates of reaction and energy changes; fuels and Earth science; separate chemistry 2 | Explain rates, fuels and organic chemistry |

The Edexcel GCSE Chemistry specification code is 1CH0.
Two papers, each 1 hour 45 minutes and worth 100 marks.
Topics 1 to 5: key concepts, states of matter, chemical changes, extracting metals and equilibria, and separate chemistry 1.
Topic 1 plus topics 6 to 9: groups in the periodic table, rates and energy changes, fuels and Earth science, and separate chemistry 2.
There are eight core practicals for separate chemistry.
Yes, a periodic table is provided.
Learn the key formulae, set out every step with units and practise a range of questions.
Yes. Tutors follow the 1SC0 specification and your tier.
The price depends on the tutor and session length. You see the hourly rate before booking, with no subscription.
Yes. Tutors use Edexcel-style questions and mark schemes.
Each paper is 1 hour 45 minutes and worth 100 marks, 50% of the GCSE.
Pearson publishes recent Edexcel GCSE Chemistry past papers, mark schemes and examiner reports on its website, and schools can access more through their secure portals. Use them under timed conditions, then mark your answers carefully with the mark scheme. Your tutor sets past-paper questions topic by topic, then full timed papers closer to your exam.
No. Both papers must be taken at the same tier: Foundation (grades 1–5) or Higher (grades 4–9).
Most schools use a student book endorsed or approved by Pearson for Edexcel GCSE Chemistry, alongside the official specification and a good revision guide. Choose a book written for the current specification so the content and terminology match your exam. Your tutor links lessons to your textbook chapters and fills any gaps with exam-style practice.
Yes. Tutors help resit students focus on the topics and question types that will lift their grade.
Learn the key definitions and equations first, then practise past-paper questions topic by topic and mark them with the official mark scheme. Give extra time to calculations such as moles, concentration and percentage yield, and to the core practicals, which are examined on both papers. Your tutor plans weekly revision around your weakest topics and your exam date.
Pearson sets new grade boundaries after every exam series, depending on how hard that year's papers were, so the marks needed for each grade change every year. Past boundaries are only a rough guide. Your tutor marks your timed practice papers against the latest published boundaries so you can track progress towards your target grade.
Practical activities you complete in class, which are assessed through exam questions.
Find the moles of reactant, use the mole ratio from the balanced equation, then multiply by the product's relative formula mass.
Weekly lessons suit most students; add extra sessions before mocks and final exams.
Start with questions on one topic while you are learning it, then move to full timed GCSE Chemistry Edexcel past papers near your exam. Mark each answer with the mark scheme and note where marks were lost. Your 1-to-1 tutor uses those notes to plan your next lessons.
