Math 3131 announcements:
Some students have emailed me and I have talked to some
others, about grades in 3131. The result is that I do not know exactly who
still has questions. Please let
me know if you still have issues about grades in the course. I think most
issues have been settled but I want to be sure.
In any case, I wish you all a successful future.
This is directed to those students who asked for higher
grades on some exam questions. I had asked most if not all
students to indicate what questions were involved. Apparently, some
students did not understand that they would have to also state
only the number of the question but also what your specific concerns
were for each question. I was barely able to assign grades is a fair way
when quite a few students were demanding higher grades on various
questions, The effect of this would be totally unfair to those students
who did not badger me. So I will stick mainly with my original exam
grades comply with this request. There may be more comments later. Bye for
Announcements for Math 3131AF_06
If you want to see your exam paper or calculations about your grades, you
are invited to come to my office during next Wednesday (10 January
2007) from 10 a.m.
to 2 p.m. If you have some of your homework or test papers and are worried
about your grades on those, please bring them with you. It is not too
late for me to make grade changes, if they are warranted. I will limit the
number of students in my office to a maximum of 3 at any one time. Barring
special cases, my deadline setting final grades is January 15.
I expect to post final grades on Friday, or if possible on Thursday. I
will not answer emails until I have posted them. I will not make any
corrections until after I have posted the grades, so please give me a
chance to get my work done. If I have made any errors they can be
corrected later; the important thing is to get the bulk of the grades in.
Corrections can be made in the following week if necessary. I will keep
time open on monday for students to read over their exam and ask about
I have graded the Math 3131 exams (see below), but I have not sorted out
grades yet. All grades are unofficial for now.
It will take a little while to get your grades. There were 29 exams. Two
students missed a
class test for medical reasons, so I will have to sort out how to assign a
for these two in a fair manner. Two other students are not on my official
class list. I
will also have to deal with that. Of the remaining 25, 1 student got a
grade in the range 90-100, 3 got
80-89, 4 got 70-79, 6 got 60-69, 3 got 50-59, 4 got 40-49, 1 got 30-39,
and 3 got 20-39.
The (unofficial) EXAM grades, sorted by last 3 digits of student numbers,
170 61(%) (170 is end of student number, and 61 is exam score out of
I will be entering letter grades soon. Please do not bombard me with
emails. I will be as quick as I can in getting the letter grades out.
They are likely a bit above the percentage grades, since homework grades
are high in general.
(6 September) Announcements (except for this one) will be listed with
the most recent announcement first. I usually include the dates of
I expect to be in office on Monday and Tuesday for quite a few hours each,
so you can ask questions about the course or the exam.
Students can get back graded homework, tests and assignments
between 4 and 6 pm today. I expect to be here much of tomorrow, December
Stuff below this is mostly obsolete, so can be ignored. I will draw
attention to new announcements.

11 at 2:30-4:30, and on Wednesday December 13 at 1:30-3:30.

- (15 September)
I will not be able to make the class on next
Friday, 22 September. This class is cancelled. Also, sometime soon I
will post the first homework (HW).
- (1 Sept)
Students who have not taken Math 2131 are not normally
permitted to take Math 3131. If you want to take Math 3131 without having
passed 2131, you must bring me a copy of your transcript for assessment.
I will make a decision based on your grades in previous courses. I will
not allow jumping to 3131 unless I am confident that you can succeed in
3131. There is no point in letting you take 3131 if you just end up
failing the course.
