FINAL EXAM: Our
final exam is Sunday, August 29th, from 3:00 to 6:00 in Kemeny 006.
The final is cumulative, but will concentrate on the final third
of the course.
SECOND MIDTERM RESULTS: As
a whole the class did well on a very difficult exam. I am still
seeing some write ups which are way too messy and terse. At this
point in your careers, that is simply immature. I will take off
more points for poorly articulated work in the future.
- Here is a hist-o-gram of the scores on the second midterm (out of 125): click here.
- For some brief solutions to the second exam, click here.
- Here is a very rough estimate of your grade in the course based
on the total of your two exams and your homework score. I have
converted your raw score on the first 5 assignments to a number from
0-60 which is written on your exam. That gives you a total out
of a possible 75 + 125 + 60 = 260. A crude estimate of your grade
to date is as follows:
- A: 217-260
- B: 170-216
- C: 144-169
SECOND MIDTERM: The
second midterm will be held in 111 Wilder from 4pm to 6pm on Wednesday,
August 4th. (This is the same room where the first midterm was
held and NOT our regular classroom.) Students with legitimate
conflicts, and who have obtained pre-approval from their instructor in writing,
can take the make-up from 6:30-8:30. The exam will cover
everything we have done on groups (that means through Friday's lecture
on July 30th and through and including Chapter 11 in the text).
The format of the second exam will be similar to the first.
Expect to be asked to state definitions and perhaps important
theorems such as The Fundamental Theorem for Finite Abelian Groups,
Cauchy's Theorem for Abelain Groups, etc.
FIRST EXAQM RESULTS: By
and large, the class did well for a first midterm. Everyone has
to work on their exposition. We are way past the point where
unjustified assertions suffice. It is especially unacceptable if
I can't follow your work. There will be more information shortly
concerning grades and the like, but for now, I have posted crude
- Minor Midterm solutions: click here.
- Distribution of scores on the first exam: click here.
- How are you doing grade-wise: It is a bit early to be giving out
letter grades -- after all this was the "minor midterm" to give folks
an idea of what to expect on the next midterm and final -- but I expect
you will want an estimate of where you stand after the exam. So I
am providing a crude conversion table for your raw score on the exam
(out of 75) to a letter grade. (Note that I haven't bothered with
pluses and minuses. I also haven't factored in the homework
scores, but on the first three assignments almost everyone is doing
very well, so including that data wouldn't change things significantly.)
- A: 67-75
- B: 40-66
- C: 27-39
MINOR MIDTERM: Our first midterm in Wednesday, July 21 from 4-6 in 111 Wilder. (NOT in our usual room!) Students with legitimate conflicts, and who have obtained pre-approval from their instructor in writing,
can take the make-up from 6:30-8:30 in 006 Kemeny. The exam will
cover through and including Friday's lecture (on July 16th).
(That means through and including Corollary 4 of Lagrange's
Theorem.) You should expect problems similar to those on
homework. You should also expect to be asked to state some
definitions and to be familiar with the results proved in class.
