O' Level Computer Books:

After you have the syllabus you need to learn your coursework. For this you need a book to study.

Remember, there is no book in the world that covers the whole syllabus of a subject so you would have to rely on self study and on-line resources like this one to cover your syllabus.

I recommend studying from this book.

Information Systems for you.

( I got an A* in Computer with this book )
