    In a classroom's personalized learning system, write a function that determines how many pairs of student proficiency scores can form compatible learning partnerships. Two students are considered compatible learning partners when the XOR of their proficiency scores results in an even number, and your task is to count all such possible partnerships from the given list of student scores.
