<p>Say you submitted your application and then decided to take the Dec SAT and then send it to them. </p>
<p>How do we know that they received the scores since it's not written on your application (you write planned for nov-but there's only room for that, none for dec)?</p>
<p>When do they actually start reading apps?</p>
<p>The UC's require apps but not test scores by November 30. They continue to accept test scores through the December testing date. They do not actually start making decisions until after the date when the testing agencies do their bulk sending of December test scores. As to whether they actually get the tests when you ask them to be sent, you need to rely on the probability that the testing agencies at least do something competently. You can try to call later to see if the UC got them.</p>
