New editions support Cambridge IGCSE Combined Science and IGCSE Co-ordinated Sciences for examination from 2025. This accessible write-in workbook is the perfect companion to the coursebook. Students have the opportunity to practice their essential science skills, including data presentation and analysis, consolidate their understanding, and apply their learning to new situations. Exercises are structured into three levels of increasing complexity, which they first support, then provide practice opportunities, and finally challenge learners. As an exercise progresses, the amount of support is reduced, enabling students to become confident, responsible learners. Answers are available to teachers via Cambridge GO.
