Topics presented as double page spreads (learning units) so that material is presented in manageable sections. The reading age has been controlled, and the text written to ensure clear and unambigous explanations. Great care has been taken with the sequencing and development of concepts, while assuming that the student had only an average grade at GCSE level. More difficult sections are clearly marked so that they can be omitted at first. Each chapter has a concise summary of the work covered. A large number of questions are included, for students to practise and develop their competence. Sections of examination questions contain AS-Level style and A-Level questions. 'Biology at Work' sections give many applications of biology throughout the book. Includes sections on 'Key Skills in Biology' and 'Study Skills'.Williams, Gareth is the author of 'Advanced Biology for You' with ISBN 9780748752980 and ISBN 0748752986.
