Grades posted. Done!

Also, just because this class is over, don't feel like you can no longer ask me questions. If you ever have a question (mathematical or otherwise), please stop by my office or send me an email. I'm happy to help if I can.

I hope you all have a fantastic Christmas break!

11/20
Our Final Exam is Monday, December 11th from 8am until 10:30am in our regular classroom WA 302.

This exam will be cumulative. I will allow one page of notes (one side of one sheet of standard sized paper). Make it count. Fill out theorems, examples, etc. that might be helpful.

I have some old final exams posted here. They should give you an idea of the kinds of things I might ask.

Test #1 is Wednesday (9/20).
It will cover Chapters 0, 1, 2, 3, & part of Chapter 4.

We have covered the bulk of what is in Chapter 0, but I don't plan on asking questions directly about this material. The one specific tool you need from this chapter is the Extended Euclidean Algorithm.

All of Chapters 1, 2, and 3 are relevant.

We have not covered much of Chapter 4. The one specific thing I do want you to know from this chapter is how to draw the subgroup lattice for Z mod n (under addition mod n). You should also know how to find cyclic subgroups and what "cyclic" means.

Overall, I plan to write a test very similar in style to recent Test #1s.

Old homework, suggested homework, notes, and the textbook are all good things to consider, but looking at old tests is probably the best way to study for Wednesday's test.

Old tests can be found here.
