<p>Is it a good idea to just leave all the hard ones blank? I'm not aiming for a 750 or something, I want like a decent 630 on the CR and 600-630 on Math. What techniques should I do to do it?</p>
<p>If you have it narrowed down to a few, I would guess.</p>
<p>i just don't see the logic in guessing at times. They say if you can eliminate one of the answers then you should guess? ***? I usually don't GUESS GUESS unless I have down to 3.</p>
<p>If you eliminate one of the answers, your chances of getting the question right is up to 1/4, you'll get it wrong 3/4 of the time</p>
<p>3/4 * -1/4 + 1/4 * 1 = 1/16</p>
<p>On average, you'll be gaining 1/16 of a point (raw score) per question by guessing after eliminating one answer.</p>
