    Design a function for an adaptive learning platform that calculates the total difficulty score across n sequential practice levels, where each level's difficulty is determined by squaring consecutive even numbers starting from 2. The resulting sum represents the cumulative challenge threshold a student must overcome to complete all n levels.
