These books are awful. They might be ok for a parent to use as a little light revision, but generally from a teachers point of view they are insulting.
People who write books like this should not try to be cool or funny, the jokes/language used go out of date very quickly and it becomes embarrasing.
Example 1: My friend thinks H from Steps is the greatest Britain ever lived, write an argument that Alfred the great is better than H... so first you have to explain who Steps were, then which one is H, then why someone might think he's great... its rediculous!
Example 2: What did Queen Victoria say when she found out she had become Queen... examples of the multiple choice answers include, 'Can I have a skateboard', 'A crown. Cool.' 'would you like fries with that?', 'no more school for me then. Woo-hoo' - this is just insulting to the child's intelligence!
We have these books at my school, which is for international children, ie: non-native English speakers and generally they find the books too easy and the jokes etc really pathetic.
If you want your kids to like history or think you are cool, don't use these books.
