IGCSE Chemistry 0620 is the Cambridge IGCSE Chemistry syllabus. It covers particles, bonding, equations, acids and bases, electrolysis, organic chemistry, and more. It is one of the most searched IGCSE subjects, especially for students aiming for medicine, pharmacy, or science A-Levels.

IGCSE Chemistry 0620 at a Glance

• Core and Extended – Core (C–G) and Extended (A*–E) tiers.
• Theory and practical – Multiple-choice, structured questions, and often a practical or alternative-to-practical component.
• Heavy topics – Mole calculations, organic chemistry (alkanes, alkenes), electrolysis, and chemical tests.

Consistent practice with equations, calculations, and past papers is key to high grades.

Revision Tips for IGCSE Chemistry 0620

• Master mole calculations – They appear in almost every paper; practise until they are automatic.
• Learn reaction conditions and equations – e.g. cracking, fermentation, electrolysis.
• Practise structured questions – Show working, include units, and use the correct number of significant figures.
• Use the syllabus as a checklist so you don’t miss topics.

How Chemistry 0620 Is Structured and Common Mistakes

The syllabus is assessed with multiple-choice, structured, and often practical or alternative-to-practical papers. Mole calculations, equations (balancing, state symbols), organic chemistry (alkanes, alkenes), and electrolysis appear in almost every series. Learn the formulae for moles, concentration, and gas volume and practise until you can do them quickly. Common mistakes: Wrong or no units (always give the unit and check conversions); incomplete equations (balance atoms and include state symbols when asked); vague explanations (explain why needs a mechanism or reason); skipping working in calculations (method marks are given for correct steps—show each step clearly).
