How much can I improve my score? Please, help me!

<p>My score on June SAT was 1680: cr-440, math-690, writing-550(essay 6, multiple-choice 59)... I was preparing for the test for a month, but not extensively, approximately 4-5 hours per day. I only had learnt 400 sat words and had written 3-4 essays before the test.
I am going to study with blue book, cracking the SAT by princeton review, princeton review 11 practise tests, kaplan 2012, barron's aiming for 2400, rocket review(at least with this books, if I need, I will use other books as well)...
Is it possible to overcome 2000 or earn 1360 ponts out of 1600(cr+math)?</p>

<p>I am an international student :)</p>

<p>it is very unlikely. </p>

<p>the ‘aiming for 2400’ stuff is not going to be very much use to you. if you’re getting those numbers, you are missing a good number of the medium and easy difficulty questions in addition to the harder ones. your efforts are better spent shoring up your ability to master the medium- and easier-level material first</p>
