| frants54 | Sometimes you learn more from the questions than from the study material itself |
| robbiecow | Second frants54 on that one! |
| chesschh | If you get this right, cosider yourself a genious |
| tkluge24 | I think III could be viewed as being incorrect as well...it would need to specify that all firms have equivalent market share?? no?? |
| chen511 | III I think it's the original sentence in the material. |
I am happy to say that I passed! Your study notes certainly helped prepare me for what was the most difficult exam I had ever taken.
