<p>So this may be a stupid question. But honestly, sometimes silly mistakes are what kill me. For example, on the SAT Subject Math II today, I got one of the absolute value questions wrong(abs(3x + 5) = -(abs(x+5)), or something like that) because I overlooked the negative. </p>
<p>So is there a foolproof way to stop youself from making silly mistakes?(Or at least reduce the chance of it)</p>
