<p>since time is always an issue for me during cr sections, i quickly read each passage ONCE, go to the questions and then pinpoint the answers. reading the passage more than once is higly unnecesary since it wastes time and you dont need to know all the minor details, you only need to know what the question is asking for. as for your second question, its all a matter of opinion; if you think it helps you, then by all means do it: just dont go on a highlighting frenzy</p>
