Resource #1

You can't go past boredofstudies.org

• It has a great resource section with; past papers, notes, assessment tasks and 'perfect' notes (detailed summaries by dotpoint).
• It has a student community/forum with sections on each individual subjects - where you can ask questions and discuss things. It also has general sections as well as buy and sell forum.
  
• They offer a "UAI Calculator" called SAM which seems to be pretty good in giving you a rough estimate, according to people in the forums.
  
• There is a premium service that gives you extra services but a FREE account should suffice.
