<p>which is better to leave it blank or guess?</p>
<p>Since there is a "guessing penalty" on the test, randomnly guessing is not encouraged. (You get -1/4 point off your raw score for each question you miss). However, if you can eliminate a couple of choices, then statisticaly, guessing will work in your favor.</p>
<p>i would guess. If you prepared, you can usually get it to 3 or 4 at least. and since your raw score is rounded, you could potentially guess on 2 and get them wrong and still get the same as having left them blank. So if you have 5-6 unsure ones, guess cause if you get all of them wrong, its just -1 to if you would have left them blank. But you'll probably get couple right.</p>
