    Design a function that generates a single-character category code for assigning personalized learning materials based on a student's assessment response. The function should convert the student's response string into a category identifier by summing the ASCII values of all characters in the response and applying modulo 26 to obtain a letter code (A-Z). This letter code will be used to map students to appropriate learning resource categories in the learning management system.
