Correspondence courses are educational programs that allow students to learn from home, typically through printed materials or online resources. These courses enable individuals to study at their own pace, making them a flexible option for those with busy schedules or other commitments. Students usually receive assignments and materials by mail or online, and they can submit their work for grading through the same channels. This method of learning has been popular since the 19th century and continues to evolve with advancements in technology, making education accessible to a wider audience.
