Dwayne and Ron plan to rent a beautiful apartment for the next school year. They can no longer afford the place after Ron's father cuts back on his allowance because of his slipping grades. They are forced to rent a dump that is managed by Velma Gaines. Dwayne and Ron throw a housewarming party and decide that their new apartment will work out. Walter looks forward to a summer of freedom, until Jaleesa announces that she has received a promotion and can visit more often than expected. They agree to spend time apart to ""sow wild oats."" Whitley plans to work at a museum all summer, but feels guilty because she would rather join her mother on a cruise. Dwayne encourages her to have fun, as there will be plenty of time to work and act responsibly in the future. Dwayne and Whitley begin to show an interest in each other.
As the school year begins, Dwayne faces the prospect of taking a calculus class from Col. Taylor, a tough professor nicknamed ""Dr. War."" He fears that Col. Taylor could expose his academic success as a fluke and destroy his dreams of becoming an engineer, so he asks Walter to help him get into another section. Walter believes that Dwayne could thrive under Col. Taylor's tutelage, and asks the professor to talk to him. Col. Taylor manages to change Dwayne's mind and convince him to enroll in his class. Whitley meets new roommate Kim Reese, a headstrong freshman who plans to become a doctor. Whitley hopes to intimidate Kim and drive her to another room, but finds it impossible to break her. Jaleesa's cheerful freshman roommate, Freddie Brooks, develops a massive crush on Dwayne.
