How to get the kinks out?

<p>On the first SAT I took i got a
Writing 630
Reading 630
Math 660</p>

<p>and on the June SAT I got a </p>

<p>Writing 700
Reading 620
Math 720</p>

<p>I raised my score up 120 points and its clear that I need to improve my reading, but besides that point, how would you guys suggest I raise my math and writing score up anywhere between 30-50 points? The first time my scores were so low that it was easy to improve, now It seems a bit harder because I only got a number of problems wrong…Any suggestions on brushing up on little “kinks”?</p>
