NCEA Level 3 Chemistry
Thermochemical principles & Properties
New outlines and revision notes for the revised Level 3 standards were prepared in 2013. However the three new externally assessed AS are not that different from the expired ones and most of the resources are still fine to use!
This page has been updated to include the 2023 questions in the collated questions.
