Twins Percy and Polly are getting ready for their first day at school. Polly is a little shy when they arrive and mum stays for awhile. Percy, on the other hand, is soon in the thick of things, and it is apparent he will be the class wag. The device of using twins is a clever one for showing how two different children with very different personalities might react to this new experience. All the busy reception class activities are shown in the humorous illustrations, even some disasters, but the teacher and assistants remain calm. The story shows school to be an upbeat, happy place, full of very individual children. A completely revised edition of a book first published in 1992.
