What this paper assessed
HSC Chemistry 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 2022 paper drew across Modules 5 to 8.
Section strategy
Section 1 in 30 minutes. Section 2 at roughly 1.8 minutes per mark. Use the data sheet and periodic table rather than recalling values from memory. For calculation chains, write a one line description of the quantity at each step so partial method marks are visible.
Common errors flagged
The 2022 NESA notes from marking centre flagged poor justification in Le Chatelier responses, weak structural formula drawing in organic chemistry, and shallow analysis of spectroscopy data where candidates identified peaks without linking them to functional groups.
What to do with this paper
Sit Section 1 in 30 minutes, then Section 2 in 150 minutes. Mark with the official guidelines. Rebuild every multi-step calculation that lost more than half its marks.
Use this paper well
