ID is the last 4 digits of your Social Security number (or another 4-digit number that you chose).  Exam 1 is your score on the first lecture test.  The high score was 104, the average was 72 (not counting those that didn't take the test).  I'll explain the scoring on Monday.  ATD is your number of recorded absences from lecture.  I will later add bonus points to your score at 1/2 point per lecture attended (10 lectures so far, so up to 5 points if you have not been absent- these points have NOT been added yet).

I'll return the exam forms to you next week, and post a key so that you can check your answers.
