Khosa completed elementary school in Sofala, and high school in
Zambezia. In
Maputo he attended
Eduardo Mondlane University, receiving a bachelor's degree in History and Geography. He then worked as a high school teacher. In 1982, Khosa worked for the Ministry of Education for over a year. Six months after leaving the Ministry of Education, he was invited to work for the Writer's Association. He initiated his career as a writer with the publication of several short stories and was one of the founders of the magazine
Charrua of the Associação dos Escritores Moçambicanos (AEMO). It was his experiences in
Niassa and
Cabo Delgado, where poorly organized reeducation camps were located, that gave him the urge to write and expose this reality. ==Literary influences==
