<p>How late can a senior take the SAT in time for admissions? Aren't most admissions due around December?</p>
<p>Applications are due starting in January, unless you are looking at early decision or early action (generally in November). Look on SAT site to see how soon scores are released. My understanding is that they are available online within three weeks or so and released to schools starting a few days after that. So, no, October test should not be too late for regular decision and maybe even for ED or EA. You should also look to see when your prospective schools expect scores and work back from there.</p>
