It facilitates the submission of assignments in various formats, including video, PDF, DOC, and images. These assignments are uploaded by students, reviewed and graded by faculty members, and subsequently made available for public viewing and rating. The primary goal is to encourage students to contribute to the development of rural communities while fulfilling academic requirements.
