The thing that bugged me the most was having a supply and demand chart for money, taking out the purchasing power of money and replacing it with interest rate. I thought that was stupid, and it is the thing that bugged me the most in economics class. When will the econ professors get the picture that this relationship only holds if the money goes directly to the lending institutions, and when will they finally understand what interest means.
I guess I am in a bad mood about the wrongness of the AP Economics test.
