This page is for Grade 12 Life Sciences learners and teachers who need a clean map of what CAPS expects — not a career brochure or a list of unofficial exam dates. Use it to organise teaching and revision against the official subject file and the current ATP.
This CAPS123 overview is not an official Department of Basic Education (DBE) publication. Weightings, formal assessment and examination detail belong in the Life Sciences CAPS (Grades 10–12), the exam guidelines your province uses, and live DBE releases.

What Life Sciences is in CAPS
Life Sciences is the study of living things from molecular level to interactions with each other and the environment, using scientific inquiry. In FET it is organised in four knowledge strands that build across Grades 10–12:
- Life at the Molecular, Cellular and Tissue Level
- Life Processes in Plants and Animals
- Environmental Studies
- Diversity, Change and Continuity
In Grade 12, teaching focuses on strands 1, 2 and 4. Environmental Studies: human impact (current crises) is taught and assessed in Grade 11 to ease Grade 12 pressure, but that work is still examined in the NSC at the end of Grade 12. Do not drop it from revision because it is not on this year’s ATP row for Grade 12 teaching weeks.
Grade 12 topic map (revision structure)
Exact week order follows your ATP. For revision, group by the two final papers commonly used in NSC Life Sciences:
Paper 1 — life processes (plants and animals)
Typical Grade 12 focus areas include:
- Reproduction in vertebrates
- Human reproduction
- Responding to the environment — humans (nervous system, senses)
- Endocrine system and homeostasis
- Responding to the environment — plants (plant hormones / tropisms)
Paper 2 — molecular biology, genetics and evolution
Typical Grade 12 focus areas include:
- DNA: code of life (including RNA and protein synthesis where required)
- Meiosis
- Genetics and inheritance
- Evolution (including Darwinism / natural selection and human evolution as set in CAPS)
Plus NSC revision of Grade 11 human impact under Environmental Studies.
Do not treat older blog “Unit 1–4” lists that insert topics such as medicinal chemistry or reshuffle Grade 10 cell biology as if they were the current Grade 12 year. Open Section 3 of the official CAPS file and your ATP when in doubt.
Assessment — use official documents only
CAPS Section 4 sets formal assessment for the subject. Schools run SBA under national and provincial rules; the NSC is externally set. Do not rely on third-party pages for percentages, paper dates or “this year’s” timetable. Check:
- Section 4 of Life Sciences CAPS Grades 10–12
- Current exam guidelines / diagnostic reports your teacher issues
- Live DBE examination timetables when published
This page deliberately does not list unofficial paper dates or claim a fixed internal/external split beyond what your official documents state for the year you are in.
How to revise without drowning
- Build a strand checklist from CAPS Section 3 / your ATP — tick taught vs revised.
- Learn terminology in context — many marks sit on precise words and labelled diagrams.
- Practise data and graph questions — not only essays.
- Revisit Grade 11 human impact with the same seriousness as Grade 12 chapters.
- Use official or teacher-issued past papers for timing; mark with official memos where available.
- Practical / investigative skills — know how to plan, record, evaluate; schools differ in apparatus, but the inquiry skills are assessable on paper too.
Teachers: sequence from the ATP, deepen from CAPS Section 3, and schedule formal pieces from Section 4 and the school SBA calendar. Learners: ask your teacher which exam guideline edition the class is using before you memorise a commercial scope pamphlet.
Skills the subject expects
Across topics you should be able to explain processes, interpret diagrams and tables, apply concepts to unfamiliar examples, and evaluate investigative design. Pair content revision with past-paper question types rather than rereading the textbook cover to cover the night before.
