Cambridge IGCSE Biology 4th Edition

New editions for examination from 2023. With endorsement from Cambridge Assessment International Education you can be confident this series fully supports the syllabus. These flexible resources have a skills development focus to help prepare the scientists of the future. Choose which components you need from our comprehensive series, comprising a coursebook, teacher's resource, workbook, practical workbook, and English language skills workbook and maths skills workbook. Through extensive research, including lesson observations, teacher interviews and work with our online research community (the Cambridge Panel) these resources have been designed to meet specific challenges through targeted support and the creation of dedicated components that focus on specific skills areas. The series supports students learning science in English as a second language; learners who need more support with mathematical content in science, the development of essential practical skills, and the building of confidence and fluency with command terms and exam-style questions.

Designed to increase your confidence, help you recognise different question types, understand connections between concepts, reflect on progress and manage test anxiety. A wealth of questions and activities improve your ability to recall knowledge and answer effectively. Your awareness and familiarity with exam language is increased by the focus on command words, time management, and the marks breakdown within and across exam papers. Self-assessment checklists and sample answers also help to deepen learning. Includes digital access and over 400 auto-marked questions and past-paper question practice. All other answers available via Cambridge GO. This text has not been through the endorsement process for the Cambridge Pathway. Any references or materials related to answers, grades, papers or examinations are based on the opinion of the author(s). The Cambridge International Education syllabus or curriculum framework associated assessment guidance material and specimen papers should always be referred to for definitive guidance.
