This work offers an imaginative new range of quick tests, brought to you by brand new characters, The Alien Club, giving children a fun way to practise key aspects of the curriculum. The Alien Club is a group of young Aliens who won a competition to go to school on Earth. The Aliens had such a good time there they now want to share what they have learnt. At the end of each book, not only do they get a certificate, they also become a member of 'The Alien Club'!
