University of South Africa (UNISA)
The University of South Africa (UNISA), also known colloquially as Unisa, is South Africa's largest university system in terms of enrollment. It attracts one-third of all African higher education students. UNISA has over 400,000 students, including international students from 130 countries, making it one of the world's mega universities and the only one in Africa. This large number of students is due to the university's distance learning program, which allows international students to easily "attend" the university. You can learn a lot more about them by visiting their website. The most notable alumnus is Nelson Mandela.
As a comprehensive university, Unisa provides both vocational and academic programs, many of which have received international accreditation, as well as a broad geographical footprint, providing students with recognition and employability in many countries around the world. Many notable South Africans have graduated from the university, including two Nobel laureates: Nelson Mandela, South Africa's first democratically elected president, and Archbishop Desmond Tutu.
