Cambridge IGCSE and O Level Computer Science Computer Systems Workbook

It is not worth paying. It is a xerox copy of the original book.

Good buy

This is a rip off by the Publisher - There are no Answers! What good is a questions book with no answers: You can only get the answers if you subscribe to a 'Boost' pack costing £135! I kid you not!

No answers in the book - these can only be accessed through the teachers guide which is only for schools to buy. I emailed the publisher to ask if they could send answers another way since we are a home educating family, but they said no :-/
