In Horrid Henry's Homework, he had a spelling that he had to practise. If you know Horrid Henry, then you will know that he didn't practise at all! On the test day, he copied every spelling from Clever Clare and ended up getting every spelling correct. The teacher was so pleased that she moved Henry up to the next spelling group which meant that he had extra words to learn. That will teach him for cheating!
These books are really funny and enjoyable to read. I would recommend them to all ages if you enjoy really funny books.
