In movies and TV shows, Beverly is usually portrayed as being full of preppy, rich Beverly Hills stereotype kids. This isn't necessarily true: anybody who has money goes to a private school, which means most of the kids who live in Beverly Hills don't even go to Beverly.
Also a popular place to go for kids who get kicked out of private school, sometimes more than once.
Person 2: I go to Beverly.*
Person 1: Oh, that's cool. Did you get kicked out of Harvard-Westlake?
Person 2: No, but my regular district school is Uni**, so I transferred to Beverly.
Person 1: Oh man, good choice.
* "Beverly" is short for "Beverly Hills High School"
** "Uni" is short for "University High School," another Los Angeles high school.
