Andrew Harvey's HSC Resources
I have a blog here. My email is andrewharvey4@gmail.com, you can send me comments there if you want, or let me know if/when links break. Unless otherwise noted these documents have been released under some form of Creative Commons license, check the license details within each document. If you require more permissions or would like to clarify the license feel free to contact me, as I'm quite keen on using CC-BY or CC0, however I can't edit the documents anymore to add this license to the documents themselves.
I no longer actively maintain these documents due to them being created in MS Word. Lesson learnt: use LaTeX.
