HOW can I focus on SAT?!?!

<p>I've been taking prac sat exams at home to help me prepare for the sat (I'm going to take real sat soon). Lately, I've been noticing that my mind wanders off and I lose focus when I'm taking a practice exam at home. </p>

<p>Does anyone have any tips on how to stay focus?? I heard chewing gum helps, but that usually makes me hungry after an hour or two. And I do underline passages in the critical reading section but I still zone out.</p>
