News & Announcements
05/07 I just posted final exam grades, final course averages, and letter grades
(as a comment on final course averages) on AsULearn. I replaced lowest test
scores with final exam scores (if it helped) and there was a sizable curve
on the final exam.
If you have any questions, please send me an email. I'll be around most of
the summer.
If you'd like to look over your exam, I'll keep them in my office for at
least a year. I plan on posting this exam along with an answer key at some
point (probably by the end of May).
I hope you all have a great summer! If you ever have any questions -
mathematical or otherwise - please don't hesitate to stop by my office or
email me. I'd love to help if I can!
05/01 Review session: Monday, May 4th starting at 3pm ending at...
...whenever we're sick of reviewing (stay for some or all or none).
We will meet in Walker 309. [Not our usual classroom.]
Office hours? Send me an email or ask me during the review session.
I should be around immediately before the exam (and most likely Wednesday
morning as well).
Don't forget: You may bring one (standard size, one sided) page of notes
to the exam.
I will take some time today to discuss what to focus on to study for the
final exam. I have posted a couple of old final exams here.
Also, there are a couple of old exams from when I taught modern algebra at
Rutgers University (Exams 1 & 2). But be warned! There course studies
mostly ring theory so there are more advanced questions than we're prepared
for on those exams. However, many of the questions make great review material.
See for example:
Exam #1: 2(skip part (e)),3-7
Exam #2: 3,5,6,7b,8a Also, I wouldn't ask 4a as it stands on your exam,
but its answer is worth looking over.
[Note: M(R) = 2 by 2 matrices over a ring R.]
04/22 Homework #7 (.pdf) is due Wednesday, April 29th. [Source: (.tex)]
04/07 Test #3 is this Friday. We'll spend most (or all) of class tomorrow
reviewing for the test.
Test #3 will cover chapters 7-11. This includes cosets, normal subgroups,
quotient groups, homomorphisms, the first isomorphism theorem, direct
products of groups, and the classification of finite abelian groups.
Old tests can be found here.
