<p>I keep running out of time. for all the other sections, i can at least look back at the ones that i'm not sure of. for CR, i NEVER have time to look back let alone finish the section with satisfaction. i keep contemplating which answer could be right and i end up wasting so much time..i also don't get as many right even though i spend so much time on them! it's frustrating. any advice?</p>
