Old/new edition of 11+ books, please help

[Hmmm]

Can someone help me - I was told by the tutor (group lessons) to buy this book https://shop.elevenplusexams.co.uk/11-e ... ory_id=136" onclick="window.open(this.href);return false;
I have a previous edition of this book but with blue cover, still not used. Do they have the same content just different covers?
