1) Goto https://students.autodesk.com/?nd=or&id=6091&ic=kAfXr15m_C  This link 
will expire on Oct 1, 2008, but the software you install is good for 14 months.

2) Fill in the form using your own e-mail address, etc. and hit submit. You should now see 
a message "Your registration is not yet complete!" All is ok, they're just wanting you to 
check your email inbox. Please move to step three.

3) Browse to your email tool (yahoo, gmail, etc.) and open the email they sent you.
Click on the link they provide. You will then be sent to a page that says "registration
successful" At the bottom of this page click on the "take me to the website" button 
then slect "software downloads." Lastly, scroll down a bit and then download the 
"Autocad Civil 3D" package; this includes vanilla AutoCAD 2009 (version we use in class).
