    Write a function that validates a student's module completion identifier, where each digit represents a learning module score, to ensure balanced progress across the curriculum. The function should verify that for each score value (digit) in the identifier, the number of times it appears does not exceed the actual score value itself. This validation ensures students don't over-concentrate on lower-scoring modules while neglecting higher-difficulty ones.
