Meet Mary-Kate and Ashley, the Tween Queen Twins! Your new best friends have just arrived . . .
Ashley is so jealous. Mary-Kate has a new maths tutor, and he's totally cute! The problem is, Mary-Kate couldn't care less about cute. Her maths lessons are making her miss basketball practice - and that means she won't be able to play in the big game!
So the twins decide to switch places. Now Ashley is working on fractions with the tutor, while Mary-Kate is working on her jump shot. But can they fool everyone long enough to get what they want?
