What Cambridge IGCSE Chemistry covers
The twelve content areas of the 0620 syllabus. Stoichiometry sits third on the list and runs through most of the others, which is why tutors make sure it is secure early.
Syllabus topics (0620)
- States of matter
- Atoms, elements and compounds
- Stoichiometry
- Electrochemistry
- Chemical energetics
- Chemical reactions
- Acids, bases and salts
- The Periodic Table
- Metals
- Chemistry of the environment
- Organic chemistry
- Experimental techniques and chemical analysis
Where students lose marks in IGCSE Chemistry
Stoichiometry is the usual weak point. Moles, masses, gas volumes and concentrations turn up in electrochemistry, energetics, acids and organic chemistry, so a student who is unsure of the mole calculation loses marks across the whole paper, not just in one topic.
Equations are the next. Balanced symbol equations, ionic equations and state symbols are expected throughout, and an equation that does not balance makes every calculation built on it wrong. Tutors drill them in short bursts in almost every class until writing them is routine.
Wording costs marks as well. Questions on bonding, rates or electrolysis are marked on specific ideas, such as the attraction between oppositely charged ions or the frequency of successful collisions, and an answer that is right in spirit but vague in wording earns less than it should.
Tests, observations and the practical paper
The syllabus expects students to know the tests for common ions and gases and what each test shows: the colour of a precipitate, the gas that relights a glowing splint, the flame colour of a metal ion. These are learnt most reliably when the student knows why each observation happens, so tutors pair each test with the chemistry behind it.
Cambridge candidates then sit either a practical test or an Alternative to Practical paper, where those tests appear alongside questions on apparatus, measurement and the reliability of results. Practising the paper from Year 10 onwards turns it into one of the more predictable parts of the grade.
Classes follow the school's order through the syllabus. A typical class checks the previous topic with a short question, teaches the new one with the particle picture drawn out, and ends with past-paper questions from the student's own board, so the style of the paper is familiar long before the mock examinations.
Who teaches IGCSE Chemistry
Tutors are university students and graduates, screened before they teach, who are matched to the student's board, syllabus code and tier. An academic advisor asks for the entry details and the latest school report before proposing a tutor.
A question, worked through
A question in the style of 0620 on stoichiometry and gas volumes. The same few steps answer most calculation questions in the syllabus.
Calculate the volume of carbon dioxide, measured at room temperature and pressure, produced when 10.0 g of calcium carbonate reacts with excess hydrochloric acid. CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂. [Relative atomic masses: Ca = 40, C = 12, O = 16. One mole of any gas occupies 24 dm³ at r.t.p.]
- Find the relative formula mass of calcium carbonate: 40 + 12 + (3 × 16) = 100.
- Find the moles of calcium carbonate: 10.0 ÷ 100 = 0.100 mol.
- Use the equation: 1 mol of CaCO₃ gives 1 mol of CO₂, so 0.100 mol of carbon dioxide forms. The acid is in excess, so it does not limit the amount.
- Convert moles of gas to volume: 0.100 × 24 = 2.40 dm³.
Answer: 2.40 dm³ of carbon dioxide.
Frequently asked questions
Do you teach Cambridge 0620 or Pearson Edexcel Chemistry?
Both. Tell the advisor the board and the code on the exam entry, and the tutor plans against those papers and their mark schemes.
How much does IGCSE Chemistry tuition cost?
The fee depends on the format (1-to-1 or a small group), how often classes run and the tutor, so there is no single figure. Message us on WhatsApp with the board, the exam session and the latest report, and you will get the current packages and a quote, usually within one working day.
My child finds organic chemistry confusing. Where do you start?
With the idea of a homologous series. Once a student sees that each family of compounds shares a functional group and reacts in the same way, the names and reactions become patterns to apply instead of a list to memorise.
Does tuition cover the Alternative to Practical paper?
Yes. It examines the practical skills in writing, including chemical tests, apparatus and results, and it improves quickly with practice, so tutors include it throughout the course rather than only before the examinations.
When should IGCSE Chemistry tuition start?
As early in the course as stoichiometry appears, because so much of the rest depends on it. The other common starting point is a term before the mock examinations, when the school report first shows which topics are weak.
