The Report Card by Andrew Clements
This book is about a girl named Nora Rowley who is a genius, but keeps it a secret! She has fooled everyone into thinking she is an "average student" by purposely missing questions on tests. She does this because she doesn't want special treatment, or for other kids to feel like they're below her. She is getting very frustrated at how everyone acts like grades are so important, and how much pressure this is putting on her best friend, Stephen. I really enjoyed reading this book. I have read it several times, and I still enjoy reading it. I highly recommend this book.
