visual studio 2005 project to 2003 project

Hi, I wnated to know if it is possible to convert a Visual Studio (visual basic) project from 2005 edition to 2003 edition project. I would like to do this because, at home, I have the 2005 edition but at school they have the 2003 edition. I would like to work on my projects at home and at school so I wanted to know if there is a way to convert them or use them with each other? I looked online but all I could find on Google was converting 2003 editions to 2005. Thanks.
