Edexcel Biology for AS is a full colour textbook with supporting Dynamic Learning website, written specifically for the new Edexcel specification.

Throughout the text there are a wide range of self-assessment questions to encourage comprehension and research, as well as recent past paper Examination questions to help students prepare for the new examination. The chapters follow the order suggested by the concept approach to the course. The Dynamic Learning website additionally provides - Extension questions to stretch the most able and extension material explaining some ideas in greater depth - How Science Works material - Additional activities - Useful websites linked to each section
