MOOCs (Massive Open Online Courses) are online courses offered by prestigious universities that allow large numbers of students worldwide to study for free. They provide video-based instruction and interaction through peer review, group work, or automated assessments. While MOOCs offer access to quality education, they typically do not provide formal qualifications and have very high dropout rates, as most students do not complete the courses. They are best suited for independent study by graduates looking to enhance their skills rather than pursuing a full degree program.
