More Practice Exam Mistakes Fixed Mon 28Jul2008 11:18AM
Apparently my attempts to fix the practice exam were not completely successful.
As of noon on Monday, the Practice Exam should be error free. Changes had to made to problems 8, 9, 20, and 22.
These were mistakes due to putting numbers in a calculator incorrectly. I want to assure everyone that the questions on the final are being double and triple checked to make sure there are no issues.

Practice Exam Mistakes Fixed Sun 27Jul2008 9:18AM There were a several mistakes on the original posting of the practice exam. They version posted now should have the fixes. In case you downloaded the practice final before Sunday morning, the changes were for problems 1, 6, 8, 9, 18, 20, 21, and 25. A few just had the incorrect answer marked on the answer key, but some need changes to either the question or answers themselves.
