No - Revit is not backward compatible. You should be able to install 8.0
alongside your 8.1 installation with the same license number.

I'm currently using AutoCAD REVIT SERIES 8.1 at home, but at school we use
8.0 is there some way to save my work at home so I can open it at school
without it saying that it won't work because it was created in a later
version? Any help would be greatly appreciated, thanks.
