This self-contained Revision Book provides support for the AQA Core Higher Student's Book but can also be used for independent study. Each double page summarises a key topic for GCSE Science and provides questions to check a student's understanding. Clear text and diagrams cover only the facts and ideas students will be expected to recall and be able to use. 'How science works' examples show how to build arguments, especially for controversial issues. Worked examples and plenty of graphs provide reminders of data handling vocabulary and show how to apply data analysis and interpretation skills. Questions are of two types - multiple choice and written answer - providing revision practice for both Specification A and Specification B exams. The questions in this Higher book are more demanding than those in the matching book for Foundation tier entrants. Answers and mark schemes are provided at the end of the book. Exam tips throughout the book from experienced teachers and examiners show how to get full marks for a question and how to avoid losing marks. There are also tips on common mistakes and how to answer questions such as 'suggest' or 'evaluate'.
