Studying a facilities management diploma helped me see facilities management from a broader and more strategic perspective. The lessons were practical, engaging, and easy to relate to real situations. The College of Contract Management maintained high teaching standards throughout the course. I appreciated the structured and logical learning approach. It is worth considering for long-term career planning.
