, 1. Introduction
The declaration of COVID-19 as a global pandemic by the World Health Organisation led to the
disruption of effective teaching and learning in many schools in South Africa. The majority of
learners in various grades spent less time in class due to the phased-in approach and rotational/
alternate attendance system that was implemented by various provinces. Consequently, the
majority of schools were not able to complete all the relevant content designed for specific grades
in accordance with the Curriculum and Assessment Policy Statements in most subjects.
As part of mitigating against the impact of COVID-19 on the current Grade 12, the Department of
Basic Education (DBE) worked in collaboration with subject specialists from various Provincial
Education Departments (PEDs) developed this Self-Study Guide. The Study Guide covers those
topics, skills and concepts that are located in Grade 12, that are critical to lay the foundation for
Grade 12. The main aim is to close the pre-existing content gaps in order to strengthen the mastery
of subject knowledge in Grade 12. More importantly, the Study Guide will engender the attitudes
in the learners to learning independently while mastering the core cross-cutting concepts.
