    Write a function that identifies and addresses the earliest unmet academic requirement in a student's progress record, where each checkpoint is represented as a binary digit (1 for met, 0 for unmet). The function should update the student's record by marking the earliest unmet requirement as complete, effectively converting the leftmost 0 to 1 in the binary representation of their academic progress.
