What happens if you get a lower score on the SAT?

<p>I got a 1500 at the beginning and now, I have a 1450.</p>

<p>I haven't submitted any of the scores, but is it possible to submit right now, the 1500 one that was taken on March?</p>

<p>Do i even have to submit any of them? Wouldn't it show up automatically in my transcript or something when i finish high school? Also, wouldn't the collegeboard just pick the one with the highest score, as long as you just don't cancel the test?</p>

<p>Thanks!</p>
