Then download it!
If you follow the link above you can download a FULLY functioning copy of Revit 2013 on a 30-day free trial. If my estimate is correct for the student community release of the software then you can activate it long before your 30-days expire!
What are you waiting for?? DOWNLOAD IT NOW!!!
