With the educational system in Nigeria, 6 years is spent in primary schols, 6years in secondary then 4 to 5 years atimes in d tertiary level.
Oh yes Nigeria has a large level of poverty rate, were a poor family is unable to provide necesary school fees talk more of the materials children need to learn fast in school. Again the government puts in less but low income in d educational system, were an average parents can not sufficiently provide for its children. Low level of educational facilities and also employment of uncertified or qualified teachers pose a big problem to the educational system.
