    Design a function that calculates the combined weight of key academic checkpoint periods in a student's progress evaluation, where the weight of each checkpoint period is determined by its corresponding binomial coefficient in an n-term academic sequence. Consider only the checkpoint periods occurring at even-indexed terms (0, 2, 4, etc.) up to the given number of terms n, and return their summed coefficients to establish the total checkpoint significance score.
