Changes in the grading policy
As the scores for the quizzes #2 and #3 are lost due to disk failure, those
quizzes are counted as 100 points for everybody. No other changes are made.
You can still drop your lowest quiz score, as desribed in the general information
section.
There are some good reasons for the procedure that we followed.
The only complaints that we have heard have been from those who did well
on the quizzes, so this addresses their concerns. Of course, similar
arguments apply to everyone.

Asking people to bring in their quizes so we can record the grades again
is really encouraging them to cheat; we have already seen some instances
of this; of course, that will hurt those who did well.

It would make very little difference for those who did well, because
almost everyone did well. The average on the third quiz was almost
80 and on the second was in the mid 90s. I've calculated this out
and in terms of the total points in the class, it could not make more than
about a 1% difference, and most likely it would be less.

It will be a lot of hassle, both for you and for us, with some chance
of other things going wrong in the middle of a complex process.
(The quiz/midterm grade will consist to 40% of the score on the midterms,
and to 60% of the score on the quizzes. )
Notes and Announcements

Office hours during final's week:
Almira Karabeg  Wednesday 23pm, Thursday 1011am
Beate/Martin  Thursday 911am AP&M 5402

typo corrected in HW8 10.1#30, R intersection S is R, not S.

Another typo corrected in HW8 the system in 10.1#32: there was a
linebreak missing between the 4 and the x in the system (!)
of equations, which reads now:
x^2 + y^2 = 4
x = y
