    Design a function that calculates a student's total mastery points across their learning journey, where mastery points for each difficulty level are determined by squaring odd-numbered challenge levels. Given n progressive difficulty levels, the function should compute the cumulative mastery score by summing the squared values of the first n odd-numbered levels.
