Skills focussed, endorsed series for examination from 2023; inspired by teachers, for teachers. This digital coursebook has been developed from extensive research through lesson observations, interviews and work with our research community (the Cambridge Panel) to meet specific needs. Activities and exercises develop students' essential skills, including practical work. English as a second language learners are supported with command terms, accessible language and glossary definitions. Exam-style questions build student confidence. Projects provide opportunities for assessment for learning, cross-curricular learning and developing skills for life. There are multiple opportunities to engage in active learning, such as role-play activities, to discussions and debates. Answers for all questions and exercises can be found online at www.cambridge.org/go.
