Power Point 2007 to older version HELP.

I am doing a Power Point for school. I have PowerPoint 2007 while the entire school has 2003 I think. So is there a way to transfer my 07 presentation via USB and keep all the text, animations and everything the same?

Because some times I lose the fonts I did on 2007 when I use it at school because 03 doesn't have them. Can anyone help me on this?

I understand that there is a way to save your powerpoint 2007 in powerpoint 2003 so it can be converted without losing any data. Try Microsoft Office Help . . .
