Not where i want to be

<p>I am a rising senior and my score is a 1500 as of right now on the SAT. I have taken a prep course and have studied throughout the whole summer, i recently took a practice SAT to see where i would be after the summer and i ended up with a 1540, and that had no help -.- .</p>

<p>I don't know if its what i studied or how i studied, all i know is that i want to be at a 1700-1900 and i only have October and November to take this test. How can i achieve this?</p>

<p>Please help!</p>
