This books about Old School is the 10th book in the popular series, Diary of a Wimpy Kid. Greg Heffley again encounters problems such as living with their grandpa, technology, etc. He faces a huge conflict when he damaged his dad's car, where he decides to go to a school sponsored camp. Once he got there, he is unable to fit in the life there, especially with no wifi or technology. Honestly, I don't really like this book because I feel like there weren't many major dramatic plots and the ending wasn't really clear. But I'll still recommend this book to Greg's fans, it's pleasant and you get to see what it's like to live from Greg's hilarious perspective. I most like this book which I read many books.
