Little more improvement possible?

<p>My scores for the June Sat are:</p>

<p>Critical Reading 650
Math 570
Writing 640 </p>

<p>Essay 9</p>

<p>I got a 150 point increase from my May sat.</p>

<p>I am dissappointed with my math scores and hope to bring it to 700 for the oct sat.
I bought the grubers sat.Is there any other book which would help me get a 700+ on sat?</p>

<p>Please recommend a book for writing as well.</p>

<p>I have an 800 math on the march. All I did, and I mean all I did, was take practice tests. The blue book has multiple tests. After each test (under ideal test conditions), look at what you got wrong. Analyze what you got wrong and why it was wrong. Then, after that, take another test until you progress. Math is highly formulaic and practice is more than enough (to put it into perspective, i did this for 2 months, and went from a 660 to 800 from January to March). Writing, I used some Kaplan writing book (forgot the name).</p>
