<p>Practice makes perfect. </p>
<p>I used Bob Miller’s book ( it is a bit digress the SAT math, for instance there are matrix and trigonometry) but you can skip those parts.</p>
<p>I addition try to study for the SAT math subject they are harder then the SAT math use
sparknotes they has a free online book that explains math concepts
