These different texts have already been published in the local journal Dévoilement, Revue interdisciplinaire de l'Université de Mbandaka. We are publishing them in book format under the title Diplôme sans science, un fléau social. The fundamental question that concerns us is the quality of education (instruction), a quality distorted by the rape of which education is a victim in the Democratic Republic of Congo, if we consider the nationals of our training structures (education), "everyone agrees on the decline in the general level of education", as Tumba states. And the same Tumba Bob warns in this that "there can be no scientific progress in a society in regression of schooling".
