    Design a function for an adaptive learning system that calculates the total complexity score of practice problems by summing the squares of the first n odd-numbered difficulty levels, where n represents the student's current progression stage. The resulting score will be used to determine the appropriate difficulty range for the next set of practice problems assigned to the student.
