Best and most efficient way to improve an SAT math score? Please help!! D:

<p>Hi guys, I'm taking the SAT for the second time on March 8, and my first time recieved a 2190.... now that's great, but to fulfill my dream of going Ivy League I'd like to have something in the mid 2200s maybe low 2300s... my scores were 790 in critical reading, 690 in math and 710 in writing. I have heard from various sources that the math score is the easiest score to bring up, but for some reason, on practice tests, etc, I rarely get about a 700. How could I raise my score in math 50-60 points? It doesn't have to be in time for the March 8 test, but since I plan to take the SAT one more time after that, any timetable would be helpful. </p>

<p>Thanks!!</p>
