I am entitled to make a mistake once in a while. I never attended Beverly Hills High School, although the book "Hard Lessons: the Seniors of Beverly Hills High School" is one of my favorite books of all time. I am sure it is out of print.
It was a book from 1988 about the senior class of 1986. It was a true story with six characters whose names were changed to be psuedonyms. I am sure a Google search or a search on Amazon will make this book show up. I wish this book was made into an R rated movie. It should be updated for the current senior class. Fast Times at Ridgemont High was based on Van Nuys High School.
