IGCSE chemistry mocks (Cambridge 0620 or Edexcel 4CH1) combine factual recall, structured calculations, and extended reasoning. Mocks expose whether you can balance equations, handle mole maths, and write clear answers when the clock is running.

Before chemistry mocks

• Syllabus tick-list — every topic appears somewhere in mock seasons. See 0620 top tested topics.
• Equation drills — balancing, state symbols, ionic equations where required.
• Calculation routines — moles, concentration, reacting masses; show working for method marks.
• Use free IGCSE chemistry notes for equation and calculation revision.
• Timed papers: Past Paper Exam Timer.

Mock technique

• Read the whole paper first — some schools allow planning time; use it.
• Structured questions — answer in the order asked; do not skip early parts of multi-part questions.
• Extended answers — link observation to particle theory or bonding where the mark scheme expects it.
• Check significant figures and units on all calculations.

After the mock

• Sort errors into calculation, equation, and explanation buckets.
• Use 0620 common mistakes.
• Turn mock feedback into better answers.
• Cambridge IGCSE chemistry grade boundaries for context.

Frequently asked questions

Which topics lose the most marks in chemistry mocks?

Moles and stoichiometry, electrolysis, and organic chemistry naming often appear in examiner reports — prioritise if mocks flagged them.

Core vs Extended chemistry mocks?

Extended papers include additional content and harder questions — match your entry tier.

How many past papers before the mock?

Aim for at least two full timed papers in the three weeks before school mocks.
