.net Framework V2.0

I just created this wicked Website for my project practicals using asp.net v2.0/visual studio 2005, it runs on the .net framework 2.0 engine,  and i just discovered that my server in school runs on the 1.1version,  my school authority have refused to upgrade now but i must present this work before 20th of march,  is it posible to downgrade to version 1.1 from 2.0?
