Claudia and the Middle School Mystery (Baby-Sitters Club, 40)

Claudia has finally gotten an A on a math test. She's thrilled . . . until the teacher accuses her of cheating off Shawna's test. CLaudia would never cheat! But is doesn't make sense that Shawna (who is a good student) would need to copy from Claudia. Can the baby-sitters help Caludia clear her name?
