    Create a function that calculates the total score of passing grades (even numbers) achieved in even-numbered learning modules to measure a student's consistent performance across major curriculum checkpoints. The function should only consider scores from even-numbered modules (positions) in the assessment history, and among those, only add up the even-numbered scores which represent successful completion of learning objectives.
