I failed too. It was the history section that really let me down.
I appreciate that it is possible to pass by preparing properly, but why should anyone waste their time learning who Sir Alfred Butler was (never heard of him) or memorising the name of the director of the belles of st trinians?
I also agree that some of the questions are horribly written. This one for example:
One of the tribal leaders who fought against the Romans was Boudicca, the queen of the Iceni. What is it known as now?
Mark One Answer
northern England
eastern England
western England
southern England
Neither Boudicca, the Romans or the Iceni are now known as eastern England. 
Neckguard I think it would take significantly more than a couple of days with a book to learn the volume of information required by the test.
