Skills focussed series, working towards endorsement, for examination from 2023; inspired by teachers, for teachers This write-in workbook with digital access is the perfect companion to the coursebook. Learners have the opportunity to practise 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: 'focus, practice and challenge'. They first develop learners' foundation skills, consolidate these skills through practice and then target higher order thinking skills. As an exercise progresses, the amount of support is also reduced, enabling students to become confident, responsible learners. Answers for all questions and exercises can be found online at www.cambridge.org/go.
