When do you send your SAT scores?

<p>I'm a senior in high school and I had already took 2 SATs (one in June and one in Oct). And I wanted to take a third time to see if I can score a little more higher ( I plan to take it in Dec). The college application is starting now and I wanted to ask WHEN and HOW do you send your SAT scores to the colleges you are applying to? Will the scores be sent on time if I take the Dec SAT? Do I need to wait till I finish the Dec SAT before I send it in? Will it affect anything? Do I need to send the scores along with my applications right now? </p>

<p>I know that's a lot of questions but I'm confused...</p>
