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
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 in writing
not 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 now.
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 possible errors. Hi all,
I have graded the Math 3131 exams (see below), but I have not sorted
out the overall letter 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 grade 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
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 announcements.
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,
Stuff below this is mostly obsolete, so can be ignored. I will
draw attention to new announcements.
(8 December, 2006) I plan to have review sessions on Monday
December 11 at 2:30-4:30, and on Wednesday December 13 at 1:30-3:30.
They will be in N501.
Here is a list of the material covered by the exam. The material
not covered by the tests will get a little extra weight on the exam,
compared to other parts. If you thing this list is wrong, please ask me
in class about it.

Office hours for Math 3131 are MW 11-12. You are also welcome to drop
by my office at other times; if I am free and not too busy, I will try
to help you.
- (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.
