Sat or Act prep in los angeles (international student)

<p>Hello i am from Ecuador , currently in Los angeles to prep for the SAT or ACT because i want to study in US. I already graduate from high school (march 2014) and i am willing to take a gap year because i know that scholarship is offered only in fall semester. Therefore i really really need to prep for the admission test. I took a practice test in elite prep and i got 1370. But i didnt like elite prep. So i am looking another that is group classes (because is less expensive). Does anyone know ?
What do you think about auto prep ? I know there are some things i havent learned in HS that is why i think i need a prep.</p>
