    Develop a function for the school's automated grading system that converts assignment difficulty indicators from snake case to camel case format, ensuring consistency across the learning management database. The function should take a snake-cased difficulty level string (like "basic_algebra_problems") and transform it into its camel case equivalent for standardized academic reports. The converted format must maintain the original meaning while following the school's data standardization requirements.
