This is a book about A-Level Computer Science. It aims to fit with the AQA GCE A-Level Computer Science 2015 syllabus but is not endorsed by AQA. It should be useful as a revision guide or to find alternative explanations to the ones in your textbook. If you haven't heard of an A-Level then this book probably won't be of much interest to you but you can find out about them at Wikipedia.
If any part of this book is unclear or even wrong then please post a comment on the discussion page or simply fix it yourself! In particular, please say if the book assumes any knowledge or skills which not all A-Level Computer Science students have.

How to read the book
You will meet several coloured boxes, here are their meanings:
What the specification says you must learn for each chapter
Example questions and how to solve them
to check if you were right
Topics that aren't examined but you might be interested in
There will be a lot of concepts that you need to be familiar with, definitions are highlighted like so:
- To be awarded an AS (Advanced Subsidiary) Level qualification in Computing, a student must take the 2 AS modules.
- To be awarded an A (Advanced) Level qualification in Computing, a student must take all 4 modules.
The book is split into the four units. Each unit is split into chapters with each chapter covering the topics for that module.
