the marks live is worth more than knowing one extra fact.

There is no Section C and no 20-mark essay. The essay (17 content + 3 synthesis) was removed after the
November 2020 exam and has not returned — it is absent from every NSC paper from November 2021 to
November 2025 and from the provincial preliminary papers used for this pack. If a study guide tells you to
prepare “the essay”, it is preparing you for a paper that no longer exists.
The content did not disappear — it was re-cut into 4-, 5-, 6- and 7-mark “Describe…” sub-questions inside
Section B. The old essay bullet lists are still exactly what you must learn; you just write six points instead of
seventeen. This pack gives you those lists in the compressed form the paper now uses.
1.2 Topic weighting — where the 150 marks actually sit

Reproduction in Vertebrates Term 1 5 8 Small but nearly free. Never skip it — it is almost always a
short, predictable cluster.

Section B question plus several Section A items.
