Assignment 27 (assigned 4/9, due 4/11):

If you did not get an A on the exam, rewrite the solutions of all the questions on the exam so that they are exactly correct.  You may use your notes.  Staple your new solutions to the exam (or hand them in together if you do not have a stapler).

If you were absent on 4/9, you will need to come to office hours or make other arrangements with me to pick up your exam.  I will be in my office today (Wednesday) as follows: 11:00-11:50, 1:30-3:00, and 4:00-5:00.  (If I am not in my office, I will be nearby, so just wait for me.)  Tomorrow (Thursday) I expect to be in my office 1:30-2:00 and  4:00-5:00 and possibly other times, but this is not quite as certain as today's schedule.  You can email me to make more specific arrangements.  I could, for instance, leave your exam with a secretary in the math office.
