In this short kid's novel, fifth grader Nora Rowley apparently got bad grades purposefully. She only tells this to a few people who she hopes can keep a secret, even though it doesn't really need to be. Anyone else like her parents, she tells that she got all D's and one C in spelling, and that was all there was to it. Behind this so-called lazy girl, her secret is she feels the smart kids and the dumb kids always get separated into different classes, and the smart-dumb factor isn't always true. Nora wants to change up some things around her school and possibly as many schools as possible. None of this is very interesting or even that clear. If that's the case, why does Nora keep this a secret from her parents?
The end result is, for a kid's book, a mess. Maybe Nora got bad grades to also get attention with her best friend, Stephen Curtis who according to her doesn't treat her normally, or maybe because of her reason and because she's generally great in school. She learns to embarrass herself and a taunter Merton Lake and such. She eventually gets herself into so much trouble as she disappoints all her teachers, that there is an assembly with all the teachers and the principal about it, plus her parents. I guess perhaps only kid's will get the message of why Nora keeps this such a secret to the adults, but I just wish Andrew Clements could have thought up some better stuff for Nora to do during her plan.
