Sending december 2010 test scores to UCLA

<p>hello, im a senior about to submit my ucla application.
i was wondering about sending my test scores, or more specifically my ACT scores.
on the website, it says UCLA will take up to the scores for the december 11, 2010 ACT's.
i took the october ACT's and i am somewhat satisfied with my scores. however, i am taking them again.
if i'm going to send whichever score that comes out better, can i wait to see what my december ACT score is before sending it or do i have to send the scores before i know what my score is? i heard that you can send the scores 3 days before you actually take the test..
if i'm not sure i'll improve my scores, will it just be better to send the scores i already have from the october ACT's??
please, help!</p>
