 If you'd like to do some review/selfstudy on methods of proof,
see
this handout on writing proofs. You might also try looking at
Reading,
Writing, and Proving, by Daepp and Gorkin.

Pictures of the Galois correspondence (click to download):
Thanks to Mike Petrillo for those pictures!

Also, check out Gallian's

Other useful links:
 If you're interested in typesetting math, the system I use to
make my handouts is called LaTeX. If you have a Windows PC, you can
download LaTeX for free at http://www.miktex.org; you will also
need a good text editor, like the shareware program WinEdt. PCTeX also makes a good commercial
version; student prices are $150 for the "Publisher" version, which I
recommend if you have the money, $50 for the "Writer" version, which I
recommend if you don't. If you own a Mac, you can download a complete
system called TeXShop for free.
If you own a Linux computer, you already own a copy of this program,
as it's been a standard Unix program for about 20 years.
LaTeX is well worth learning, if you have some free time; it's used
for manuals and technical reports throughout nerddom. For
selfstudy, I highly recommend Learning
LaTeX (Griffiths and Higham) for beginners, and the
LaTeX book by Leslie Lamport as a reference.
