IGCSE Combined Science 0653 Study Guide

About this guide

Closely following the 0653 syllabus, it presents all three disciplines in balance, from cells and chemical reactions to electricity and forces. The content is distilled and concise, focused on what matters for the exam.

It is an efficient way to master core science in English while saving time compared with studying three separate sciences, and it also prepares students well for the practical exam questions.

What is inside

• Biology: cells, nutrition, respiration, photosynthesis and the human body
• Biology: reproduction, inheritance and relationships within ecosystems
• Chemistry: atomic structure, chemical bonding and the Periodic Table
• Chemistry: acids, bases and salts, reactions and rates of reaction
• Basic organic chemistry and applied chemistry
• Physics: forces, motion, energy and pressure
• Physics: heat, waves, electricity, magnetism and atomic physics
• Combined practice questions across all three disciplines with answers

Who this guide is for

• Students taking Combined Science 0653 instead of three separate sciences
• Anyone wanting a broad science foundation studied in a streamlined way
• Students who do not plan to specialise in science at a higher level
• Parents looking for an accessible integrated science resource for their child
• Teachers who need revision material covering all three disciplines

How to use this guide

• Rotate your study schedule across the three disciplines to keep your knowledge balanced
• Build a separate table of formulas and terminology for each discipline
• Draw mind maps linking the concepts within each discipline
• Practise describing experiments to prepare for the practical component
• Work through the combined questions at the back of the book to get used to how the exam mixes the three areas
