The International General Certificate of Secondary Education (IGCSE) Biology Module 4 is the fourth in a set of four books developed by the Cambridge Open Learning Project (COLP) in South Africa. The Project aims to provide access to quality education by producing course materials to support the University of Cambridge Local Examinations Syndicate (UCLES) biology syllabus for IGCSE. The IGCSE examinations are available through the Southern Africa office of UCLES, based in Cape Town.
