Path to increasing SAT score?

<p>Hello, I am going in to my junior year and i am currently studying for the SAT using the "Get 800" series of books by Steve Warner. And am learning a plethora of vocabulary words. But is there anything more?, i have a reputation for stressing stuff, but it is only because i want to make sure i do the best i can, my goal is to hit a 1500 or higher (750 math 750 reading). Am not worried about writing since the military doesnt really care about it. So any tips of prep course suggestions would be awesome, as well as some statistics of how it helped you. Thank You :). Oh and i am taking it on October 5th</p>
