<p>I went from 1700 on the real sat to an average 2000 on practice tests within a 6 week span. Primarily I increased the math by minimizing errors, not so much not knowing how to solve a problem, but rather reducing minor mistakes, Learned like 500 words, 100 every day, but I only did it once a week :). I recommend flash cards. And not that much on writing sadly.</p>
