I really liked this book because I thought the combination of writing and cartoons was really good. It expressed Gregory's (the main character) point of view of school and the summer holidays. I thought it was very funny and I like how Gregory thought he will be rich and famous when he's older.
The basic storyline is Gregory is going from the end of vacation to the first few weeks of school and his perspective of things that happen in his family and at school. I find the characters in the story convincing and I have to say that I have compared many of them to people I know in real life!
I think this book is less for 11 year olds, more for 9 year olds but that doesn't stop me from giving it 80 out of 100.
