how to improve my score?

<p>Currently i have 570 for math, 580 for writing (10 essay), 490 critical reading.
I was wondering how i could raise that up in a month (I'm taking the Jan. test)</p>

<p>Is it helpful to take a test everyday (blue book)?
Is it not really helpful to study if i want my score to drastically improve from 1620 to 1800?
How severely do i have to study? Is there a way to raise my CR score?? If so, how (according to your experience)?</p>
