The aim of this book is to provide detailed coverage of the topics in
the new OCR AS and A Level
Computer Science specifications H046 / H446.
The book is divided into twelve sections and within each section, each
chapter covers material that can
comfortably be taught in one or two lessons. Material that is applicable
only to the second year of the full
A Level is clearly marked. Sometimes this may include an entire chapter
and at other times, just a small
part of a chapter.
Each chapter contains exercises and questions, some new and some from
past examination questions.
Answers to all these are available to teachers only in a free Teacher's
Pack which can be ordered from
our website www.pgonline.co.uk.
This book has been written to cover the topics which will be examined in
the written papers at both
AS and A Level. Sections 10, 11 and 12 relate principally to problem
solving skills, with programming
techniques covered in sufficient depth to allow students to answer
questions in Component 02.
Pseudocode, rather than any specific programming language, is used in
the algorithms given in the
text. Sample Python programs which implement many of the algorithms are
included in a folder with the
Teacher's Pack.
