Computer Science 280: Discrete Mathematics
Late-Breaking News
- Final grades are now available; send me email if you want yours (apparentely I can't post the grades). Here is the overall picture: The mean (and median) were 80. I made 80 the cutoff for B+. You needed 85 or better to get an A (that is, A-, A, or A+), 72 or better to get a B (that is, B-, B, or B+). About 34% of the class had A's and another 44% had B's.
- The final is graded; the mean was 48/60. Here are the solutions. Stop by 4146 Upson to pick yours up. Also please pick up all your old homeworks and your prelim. I will throw them out next week.

Newsgroup
There is a newsgroup for the class:
cornell.class.cs280. You should subscribe to the newsgroup. Post
questions to the newsgroup regarding homework (or anything else relevant
to the course), and one of the TAs, graders, or me will try to answer
it..
Homework
Handed out every Friday, due the following Friday,
at the beginning of class. THERE WILL
BE NO EXTENSIONS GIVEN. There will be about 12 problem sets altogether.
To compute the final homework grade, the lowest two will be dropped.
If you miss handing in an assigment (for emergency, illness, whatever),
this will be among those dropped.
It's OK to discuss the problems with others, but you must write up
solutions on your own. Not to do so is a violation of the Academic
Integrity Code.
Note that there are homework assignments posted here for several weeks
ahead. The future assignments are still tentative; they're just here to give you some idea of where we're headed.
