What this paper assessed
HSC Biology is one paper of 100 marks across 180 minutes plus 5 minutes reading time. Section 1 is 20 multiple choice (20 marks). Section 2 is short and extended response (80 marks). The 2023 paper kept the standard weighting across Modules 5 to 8.
Section strategy

Common errors flagged
The 2023 NESA notes from marking centre flagged confused descriptions of gene expression, weak distinctions between innate and adaptive immunity, and superficial responses on non-infectious disease that named diseases without explaining causes, treatments and prevention.
