		- some matching, some multiple choice, some true false, but
                  there will also be some short answer as well

       	          The same rules that apply to quizzes will also apply here.

       		  Access code will be emailed to your ISU email

Exam grade note: If student does better on the final than on the midterm, then
                 I'll drop the midterm entirely and only use the final to 
                 calculate exam grade

Everything we've covered so far is fair game for the exam

How many questions specifically? TBD, but definitely more than the quiz
