We use the Leading Edge (Dixon/O'Mahony) in class plus the Leading Edge Workbook. I also use the Excel to study from occasionally, but mainly only when i can't be bothered reading through the huge amounts of info that the Leading Edge book provides. Excel is good for short summaries of the info. Best for revision once youve learnt all the work from another text.
We have another excellent resource though. Our teacher is a walking, talking economics machine. We all think he dreams about it coz he knows so much. Its great to have a teacher that can not only basically recite the whole course off the top of his head, but actually teaches it all to us as well.
His motto - Economics Lives People... Economics Lives
Another resource we use is the Leading Edge monthly economic updates. They are great. They have articles in them about the most significant economic developments over the past month and also have a section on the back that tells you all the current stats. E.g. CAD, Net Foreign Debt, Unemployment Rate, Inflation Rate etc.
