I looked it over, and the notes look good, but could someone who's actually completed Global Politics under the current study design confirm how relevent the content is?
Well, under the current study design Unit 3 AOS 1 of the old IntStudies one is still present, pretty much in the same form (except for the omission of globalisation and internationalism), so that one's fine, but the other AOSs really depend on what specific topics your school has chosen to do (e.g. Inter-intra state conflict, in depth study of Australia or China for Power in the Asia-pacific). Personally, I think these notes are admirable, but they haven't been of any use to me so far, there are much more relevant notes out there.
