Computing : No books mentioned in the syllabus. However, I used 'A' Level Computing 5th Edition by P.M. Heathcote & S. Langfield published by Payne-Gallway. I think you can order it at their website,
www.payne-gallaway.co.uk . However, it is for the AQA Board but I used it for my CIE Exam and scored an A. Always found computing a piece of cake, so dunno if the book is that tight but it's what I used.
I only took Computing from all these subjects, picked out the endorsed books from the syllabuses for you. Hope it will be useful.
Good Luck.
