"I know that Tabitha is ready for school, but is school ready for Tabitha?" warns Sam. Tabitha attends school for the first time, and has a pretty hard time because a boy is messing with her. When he refuses to give up, Tabitha turns him into a frog. The teacher Miss Peabody gets on her about the frog and tells her to put it back in the class terrarium. Tabitha grabs the wrong frog and Samantha pops into the school and changes the frogs. When the right frog is brought home, Tabitha changes it back before the boy's mother finds out.

Tabitha has to take a test to prove her intelligence and is very nervous. Endora helps her out by puuting a spell on her, making her a super genius! Miss Peabody, the teacher from episode 246, is amazed about Tabitha's knowledge and tells the principal about it. Samantha find out about this, and tells Endora to take the spell off Tabitha. Miss Peabody will not back off, and she catches Tabitha and Adam using their powers one day. Samantha catches Miss Peabody trying to be like Gladys Kravitz and gives her a lesson about snooping she will never forget.
