Year 12 Videos

Videos

Mostly videos made by me, but with some others.

The main purpose is to allow students to catch up material they have missed – which is why there are often notes included in them for students to take down – or revise before an assessment.

I have indicated where the level is above what an Achieved level student should be prepared to do.

This page does not have the videos embedded, to save on download time and make the page easier to navigate. Instead the links open a new page in YouTube (or similar).
