how much time do I need for the SAT??

<p>hi all
I am going to be in the US this year in June , I will apply to the college at the fall semester and I will be starting my classes in 19/Jan/2014.
basically I will spend my first 3 months in the US working on my Language and improve it,but I am thinking about taking the SAT exam although my college doesn't require SAT scores for International students but I might get a scholarship if I have a high SAT score.
so I will have about 3 other months of free time after finishing the language courses,is that enough time for the SAT??
and how much does the SAT exam coast ??</p>

<p>best;</p>
