Hey, I'm also applying to AIM. The way I read this is that it is limited to one page, so it doesn't have to be a page long, that is just the maximum. Also, I can't say for sure but I think if you single space or double space (your choice) it and the statement fits on one page, it should be fine.
Can anyone confirm this for sure?
