    Given a list of student achievement scores from learning modules, determine the number of student pairs whose scores, when XORed together, indicate learning pattern compatibility (resulting in an even number). The paired scores represent potential study group matches in an adaptive learning system, where compatible learning patterns are essential for collaborative learning success.
