I understand that many open response questions need to be graded by hand by the instructor, so the score I see when I submit this test is not my final score.  I also understand that tests may not be manually graded until after the testing period is over (so the instructor can do them all at once).  [a]   I agree not to discuss this test with other students (regardless of whether I believe they have completed it or not)  until the solutions are released to the class.
