Class 507 is the worst class Ms.Bryce has EVER taught.And she would know-she's been teaching forever.They are so terrible that when a science experiment goes disastrously wrong (again),Ms.Bryce has had it and quits in the middle of the lesson.But though a mix-up,the school office never finds out. Which means . . . Class 507 is TEACHER-FREE! Can they keep the principal,the rest of the students,and their parents from finding out . . . or will the greatest school year ever turn into the worst disaster in school history?All Rights Reserved
