SAT Prep vs ACT Prep

<p>I'm a rising senior and I'm going to take a prep course at the end of this summer. The problem is that I don't know if I should take it for the SAT or the ACT. My highest scores were a 26 and a 1750.</p>

<p>Any suggestions?</p>

<p>If it matters I live in California and I'm applying to UCs and a few east coast schools.</p>
