the notes and stuff that we get from class are pretty much directly out of the book, my school uses 'Journey Through Health and Human Development'
Pearson - Schools Title: Journey Through Health and Human Development: VCE Units 3 & 4
but there are other books, I think?
I think they would sell it on ebay. Maybe you could buy it from there?
And alot of answers are on the internet. World health organization is a great site to go look at.
