The book I’m looking for was in the late 80s/early 90s. It was about a group of high school students who were all missing an extracurricular activity, so they were assigned to create the school’s yearbook to fulfill that requirement to graduate. There was the pretty blonde from an upper middle class family, an artsy/misfit type girl, and a loner guy who turned out to be wealthy, and at least one other student (maybe an athlete?). It was almost like Breakfast Club, but in a yearbook class setting. I think it had yearbook in the name, but I’m not entirely sure, and searches for yearbook haven’t brought up this book. Any help is appreciated!
Lost Classics of Teen Lit: Name That Book! 
This reminds me of the book In a Class by Herself by Ivy Ruckman. It had a sort of Breakfast Club vibe and had a mishmash of students from very different backgrounds coming together for some sort of writing club or extra curricular activity.
