    Design a function that analyzes student performance data from multiple learning modules, where each module's data is represented as a sequence of responses, and extract only the final achievement level reached by students in each module. The function should process a tuple containing these response sequences and return only the last character from each sequence, representing the student's ultimate performance level in that specific module.
