In regards to the textbook we didn't use a particular one, I personally went and bought
The Indigo handbook for national politics / Rod Wise. (it's mroe like a study guide, really good but skips a lot/doesnt go into detail, so you need to COMPLIMENT IT with another)
Power and national politics : VCE National Politics unit 3 & 4 / Paul Gilby ; content editor Maryellen Davidson.
Good, detailed, and practically the only "textbook" available in Victoria for National Politics.
The key to success is to do your OWN research and get your own NOTES.
Because you use the textbook for about 2/3 of the course, the rest involves you choosing a DOMESTIC policy, and a FOREIGN policy....this is where your own notes, video viewing, news watching, internet research come in handy
