The final is on 12-2:30 PM on Thursday, May 13 in Philips 101.
There will be a review session on Tuesday, May 11, at 7 PM, in Upson
205 (which should accommodate 60). There will be office hours as usual
on Monday, Tuesday, and Wednesday. You can pick up your old homeworks
from Cindy (in Upson 4146) on Monday, Tuesday, and Wednesday.
Finally, here are some old CS280
exams and solution. Note that this year we did number theory and more
probability than in previous years (in particular, things like the Law
of Large Numbers, Markov and Chebyshev Inequalities, and the Central
Limit Theorem were not done before), but did not do graph
theory (which is now mainly done in CS211). So this year's exam will be
somewhat different from those in previous years. You can ignore all the
graph theory questions from previous years.
Good luck on the final!

flyer.

The prelim is in Olin 155, the same room as the class.
Olin is locked at night. There's a combination lock on the door in Ho
Plaza. The combination is 153 (you press 153, then turn the knob
clockwise). Please come to the exam at 7:25, 5 minutes early, so you're
set to go at 7:30. The prelim will run until 9 PM.

Here are solutions for the 2003
prelim and the 2000 prelim.

More help for the prelim: For next week only,
Joel Ossher and Tom Church have moved back their office hours from
Wednesday to Monday. That means we have two hours of office hours
today, four on Monday, and three on Teusday.

To help you study for the prelim:
- The review session is set for Sunday (March 7), 7-8:30PM, in Upson
111.
- Homework 7 has been posted. It is not due until
March 17, but you may want to look at the questions from Sections 4.2
and 4.3, to help you in preparing for the prelim.
- Mahesh's office hours have been moved (for this week only!) to
3:30 - 4:30 on Friday, March 5 (instead of 2-3 on Thursday, March 4).
- There may be a few other office hour changes for next week, so that
we have more office hours on Monday and Tuesday before the prelim. Watch
this space for more details.

The only type of calculator that you can bring with you to
the prelim is one without any memory or programming capability. If you
have any doubt about whether or not your
calculator qualifies it probably doesn't but feel free to ask one of
the professors.
Feb. 28
To prepare for the prelim, you may want to check
the 2003 prelim and the
2000 prelim. However, note that this
year we did not cover graph theory, but did cover number theory.
Neither prelim has number theory questions; both have graph theory
questions. You should ignore question 7 on the 2000 prelim and
questions 8-11 on the 2003 prelim.

Mahesh's office hours on Thursday were mistakenly
listed as being from 3 to 3. They're actually from 2 to 3. Also, they
will be held from now on in his office (4121 Upson), not 328C Upson.
Feb. 20
As announced in class, the prelim will be Tuesday,
March 9, at 7:30 PM. If you have any conflicts, please send
Prof. Halpern and Prof. Keich email as soon as possible. Also note that
solutions to homework and course grades are available at the Course Management System webpage.
Feb. 5
Please make sure to staple your homework and attach this
grading sheet, either to the front or the back
of your homework. This will make it much easier for us to report your
grades. If you forget to do it after this week, we'll
deduct two points from your homework.
