Do colleges really stick to the LAST POSSIBLE SAT test date?

<p>I see it on their website all the time where they say that the last possible date for instance is the December SAT. Is this true? Is it possible to take the SAT in January then send those score in? Why this deadline?
I know im flooding with questions but I'm just curious since SAT's are tomorrrow and im not ready!</p>

<p>If I wanted to give myself the best chance of acceptance I would meet my target schools' deadlines for test scores.</p>

<p>yeah i thought so too. My SAT is in an hour!! wish me luck!
i live in kuwait so im like 8 or 9 hours ahead of you guys!</p>
