    As a teacher managing adaptive learning, you need to determine the highest possible benchmark score that can be set using the available student performance metrics from recent assignments. Given a list of single-digit performance indicators (where each digit represents a student performance metric), create a function that arranges these digits to form the maximum possible benchmark score that will guide future assignment difficulty levels.
