Thereafter, he was in Ibadan Grammar School between January 1961 and 1967 where he passed his West African School Certificate and the Higher School Certificate examinations. He was admitted to the University of Ibadan in 1968 to study Botany but later changed to Geology in which he graduated with a B.Sc. (Hons) degree in Second Class Upper Division, in 1971.
