    Write a function that analyzes pairs of student assessment scores to determine how many pairs would be compatible for grouping study recommendations, where compatibility is defined by their XOR operation resulting in an even number. Given a list of student performance scores from various assessment modules, the function should count all such compatible pairs to help optimize study material suggestions.
