<p>SAT math is actually very easy to improve. a 680 to 750 is not unlikely given the time that you have. </p>
<p>I suggest practicing, practicing, practicing, and getting to know the TYPES of questions and the TYPES of answers on the test. Analyze which types of questions (ie- geometry, probablity, etc) you are having the most trouble with and study those from Gruber’s or other prep books.</p>
