How to work through IGCSE Chemistry
- Do States of matter, Atoms and Bonding first. Every explanation later depends on particle arrangement and bonding type.
- Answer every property question in two steps: name the structure and bonding, then explain the property from it.
- Learn the tests as reagent, observation, conclusion. Topic 12 is the cheapest set of marks on the syllabus.
- Practise stoichiometry through moles every time, even when the ratio looks obvious.
