SAT I vs SAT II

<p>I was wondering which SAT is more important and also the best interest for me to take the SAT this week so I have a better chance of getting into a UC university.</p>

<p>For the SAT Reasoning Test I have a 1680 (Math: 650 CR: 520 Writing: 510)</p>

<p>For the SAT II Subject tests I have:
Chem: 660
US History: 600
Math IC: 640</p>

<p>As you can see, by looking at my SAT scores, which SAT should I'd be taking this week? SAT Reasoning or SAT II?</p>

<p>Another question: Is it REQUIRED for freshmen applicants to take the Math IIC? My father and I are kind of confused. <.<</p>
