The final is takehome final I will post problems on
Thursday Dec.7 at about 10 AM. The exam is due on Friday Dec. 8^{th}
at 5 PM. You will need to return your work to Hassan (He will be
in his office JFB 212A at 45 PM) or in my mailbox in the department office. I
the latter case you need to ask office attendant to put a time stamp on your
work. 
(coefficient of difficulty
1.15) IMPORTANT FOR ME
(and future students) Please answer the
questions about the content of the course and return the question sheet. alongside with your
final.
