Test Scores Question

<p>I took the SAT twice and I did awful on the math section. So I decided to take the ACT in December and I feel like I did way better on that test. However, ACT scores become available around December 28th ish and the colleges I'm applying to have the deadline of January 1st/2nd. So I have a dilemma (assume each school allows Score Choice):</p>

<p>Do I send my common app out now and leave the test score section blank except say I took the ACT in december and put my SAT subject test scores? Or did I wait until December 28th to fill in my ACT score?</p>

<p>But what if I did worse on the ACT than the SAT..isn't it premature to start banking on a score I don't know?</p>

<p>I need some advice. Thanks.</p>
