I am looking for a book that was probably written in the 1950s or early 1960s.  It was a part of my grade school library, a school that converted from a K-12 school to a K-8 in 1965 or so.  The book might have been written as a young adult novel.  It was about a teenage girl and her dealing with high school life (boyfriends, homework, mean girls).  I do remember that one chapter was titled “The Kangaroo Court”.  I do not remember the very much more about the book, but “Pink” comes to mind – either part of the title or another chapter.  I hope this jogs someone’s memory!
