please help me

<p>i took the SAT twice already and barely any improvement.
first time in november:
math 580
cr 580
writing 500 essay 6
total 1660/2400 or 1160/1600</p>

<p>second time in march:
math 640
CR 510 (***)
writing 570 essay 8(beautiful essay score imo)
total 1720/2400 or 1150/1600</p>

<p>i took a princeton review course for the second one. ***!and i also tried to prep by myself.
ofcourse, the princeton review course was a joke cuz the school was paying for it for about 80 students so it was crazy.</p>

<p>i am tking a revolution prep course for the june sat and i desperately desire at least a 1900.</p>

<p>how can i improve?</p>
