Question about submitting to schools on test day

Hi All-

I am taking the test in two weeks and prepping non-stop.

Anyways, this question is regarding submission of scores to 5 schools before taking the test. I am undecided, but am likely applying to a handful of schools this fall, and possibly different ones next fall if I get dinged...

1) Should I just submit the scores to the top five schools I am interested in, regardless of when I plan on applying?
2) If I send a score to a school, will they be expecting my app during the next round or next year, or does it just live in a database for whenever I am ready?
3) Do I have to apply to a school if I send a score to them, or at least let them know when I am?

Basically, I want to make the most of my 250$ fee, but am not sure when and if I'll even apply to each of the 5 schools... Any guidance would be greatly appreciated.

Thanks
