Students and educators who are members of the Education Community get free access to Autodesk Univeristy 2009 Virtual passes by signing up from the promotion in the community. AU is Dec. 1-4 this year, but by sigining up for AUv, you'll get access to over 400 classes on demand for the entire year!
Just go and login to the Student Community... there is a banner on the right hand side with the promotion. Enjoy!
Thanks for thinking about us students Autodesk!
