SAT ! improvement? possiblity?

<p>hello.
i'm a sophomore, i'll be a junior next month.
My last practice test was last week and i got a 1710.
600 math, 530 CR and 580 Writing
im wondering if i can get at least a 2100 by my early senior year?
Math im not so strong in, but Writing and CR i'm improving a little by little.
I take practice tests every saturday and i really want a 2100 minimum.
How can i improve? any recommendations?
My grades in school are 4.3 weighted for sophomore year.
but i think SATs are a completely different thing..
and last thing! do you recommend any books that are useful for writing essays?
I get usually 8-9 on the practice test.
i think its out of 12?
thanks everyone!</p>

<p>Anything’s possible. It’s not very likely, but you might be able to do that. There are a bunch of threads on the best books, but you need to get the official book at the very least.</p>
