OCR A2 Chemistry builds on the units studied at AS and provides comprehensive coverage of Units 4 and 5 of the A2 specification. Each chapter focuses on the unit modules and includes a wide range of examples to equip students with the skills to succeed in the examination. An important feature of the specification is the inclusion of centre-based practical assessment, so a further chapter is included to provide a clear discussion of the skills required for tackling this component. An accompanying online resource includes chapter summary worksheets and sample exam-style questions, together with graded answers and detailed commentaries. OCR A2 Chemistry includes the following special features: Examiner's notes -- invaluable content guidance and exam advice Worked examples -- detailed explanations of calculations and exam-type questions Stretch-and-challenge material -- extension topics and questions at the end of each chapter Answers to all review, extension and summary worksheet questions are provided in an accompanying Teacher Guide, which is available for purchase by teachers.
