Well "perfect" notes should consist of the following (in my opinion, other students feel free to add)
-Glossary of key terms
-Description of all key concepts [Use the Study Design as your guide]
-Examples of companies for different scenarios
-Possibly mind maps/concept maps outlining each area of study; helps link everything together
That's about it I think, and remember what's perfect for someone else, may or may not be perfect for you.
As for the examples, as I mentioned above when we say examples we mean an example of a company that conducted itself in a particular way... Hope that makes sense, if not I can elaborate.
The Age Business Section would be your best resource, so don't throw away that article, just because its "old" it doesn't mean it wont be helpful, try keep upto date with the business world, but don't stress too much if you cant. Just try to work with whatever examples you remember well.
Good Luck
