    Create a function that processes a student's learning path description by removing advanced topics (marked in uppercase) that are beyond their current skill level, ensuring the curriculum matches their learning readiness. The function should take a mixed-case text string containing course descriptions and return a modified string with all uppercase segments removed, maintaining the remaining content's order and spacing. The resulting learning path should preserve all lowercase and mixed-case content while eliminating any fully uppercase sections.
