T.J. skips grades and enters high school at age 10.

In the opener, T.J. has trouble learning the ropes outside the classroom and pays the price for breaking ""The Code,"" which states you never rat on a friend. The friend in question is Mo, a star player on the school's basketball team. When T.J. tattles on Mo for smoking in the boys room, Mo is suspended from the team and misses an important game. Ostracized and unhappy, T.J. hatches a misguided plot to make amends by sabotaging the rival team's report cards.

Two twin sisters move to the school. Marcus gets a date with the pretty cheerleader, but unknowingly mistakes her for her smart twin later. As he realizes how much he likes them both, Marcus sets up a plan to date them both. The cheerleader will date Marcus, while the intelligent one will date ... Marquis.

When the keyboard player in Marcus' band breaks his finger, T.J sits in. Meanwhile, Yvette is mortified when her friend admits having a crush on her dad.

When Mo and T.J. are teamed up by their biology teacher to observe animal behavior, T.J. decides they'll watch his brother Marcus and sister Yvette.

Yvette is convinced T.J. is dying to go to the prom, despite his protestations, so Floyd gets him a date -- then Marcus gets him a date -- then Yvette gets him a date....
