Document 7: Kenya: The African Great Lakes region, which Kenya is a part of, has been inhabited by humans since the Lower Paleolithic period. By the first millennium AD, the Bantu expansion had reached the area from West - Central Africa. The borders of the modern state consequently comprise the crossroads of the Niger - Congo, Nilo - Saharan and Afroasiatic areas of the continent, representing most major ethnolinguistic groups found in Africa. Bantu and Nilotic populations together constitute around 97% of the nation's residents. European and Arab presence in coastal Mombasa dates to the Early Modern period; European exploration of the interior began in the 19th century. The British Empire established the East Africa Protectorate in 1895, which starting in 1920 gave way to the Kenya Colony. Kenya obtained independence in December 1963, but remained a member of the Commonwealth of Nations. Following a referendum in August 2010 and adoption of a new constitution, Kenya is now divided into 47 semi-autonomous counties, governed by elected governors.

Secondary schools have "college" as part of their title.  The government of Mauritius provides free education to its citizens from pre-primary to tertiary level. In 2013 government expenditure on education was estimated at about Rs 13,584 million, representing 13% of total expenditure.

Document 12: Republic of the Congo: Public expenditure of the GDP was less in 2002–05 than in 1991. Public education is theoretically free and mandatory for under-16-year-olds, but in practice, expenses exist. Net primary enrollment rate was 44% in 2005, much less than the 79% in 1991. The country has universities. Education between ages six and sixteen is compulsory. Pupils who complete six years of primary school and seven years of secondary school obtain a baccalaureate. At the university, students can obtain a bachelor's degree in three years and a master's after four. Marien Ngouabi University—which offers courses in medicine, law and several other fields—is the country's only public university. Instruction at all levels is in French, and the educational system as a whole models the French system. The educational infrastructure has been seriously degraded as a result of political and economic crises. There are no seats in most classrooms, forcing children to sit on the floor. Enterprising individuals have set up private schools, but they often lack the technical knowledge and familiarity with the national curriculum to teach effectively. Families frequently enroll their children in private schools only to find they cannot make the payments.
