"Tawny got her test paper back from Math class and she passed, but Jessie didn't do so. He got a C+ and now he's afraid to tell his mom. The last time he didn't do well on a test his mom took him off the soccer team. After a discussion over lunch, Tawny and Jessie come up with a plan to meet after school to see about switching his grade. Just as they were about to get themselves into trouble Mrs. Johnson came out of the house just in the nick of time to stop them from making a Great Grade Switchup."--back cover.
