On this page you will find Life Sciences Grade 12 Exam Guidelines Scope for 2025 final exams.
The guidelines apply to both Paper 1 and Paper 2. Learners will write Paper 1 on 14 November 2025 and Paper 2 on 17 November 2025. Each paper is 3 hours long, carries 150 marks, and assesses a balance of knowledge, application, and problem-solving.
Life Sciences Grade 12 Exam Guidelines Scope 2025 – What to Expect
The Life Sciences exam is divided into two separate papers, each focusing on specific topics taught across the school year.
Paper 1 – Human and Plant Systems
Date: Friday, 14 November 2025
Duration: 3 hours
Marks: 150
Content and Weighting:
- Reproduction in Vertebrates (5%) – 8 marks
- Human Reproduction (27%) – 41 marks

This paper covers molecular biology, cell division, classical and modern genetics, and evolutionary biology, with a strong emphasis on genetics and evolution.
Conclusion
The Life Sciences Grade 12 Exam Guidelines Scope for 2025 confirms that learners will write two 3-hour papers. Paper 1 on 14 November focuses on human and plant systems, especially reproduction, responses, and homeostasis. Paper 2 on 17 November focuses on DNA, meiosis, genetics, and evolution. Together, the two papers carry a total of 300 marks. Learners should balance their revision between human systems (Paper 1) and molecular biology and evolution (Paper 2), while practising past exam questions to strengthen problem-solving and essay writing.
