    Design a function for the school's adaptive learning system that determines if a given difficulty rating can be broken down into a difference of perfect square numbers, which helps categorize math problems for appropriate student skill levels. The system uses this classification to automatically adjust assignment complexity based on class performance in number theory topics. The function should return true if the difficulty rating can be expressed as a difference of two squares, and false otherwise.
