<p>If you can eliminate some answers guess. If you have no clue omit altogether (leave blank)???? </p>
<p>Is this the right approach, or should you answer every single question, even if it means guessing 100%?</p>
<p>Well if you guess you risk loosing 1.25 points but also stand a chance at gaining 1 point. If you leave it blank you loose 1 point off the bat. I think that especially for a subject like WH where the curve is something like 10-15 wrong and still an 800, you can guess quite a few questions. However, I normally wouldn’t guess for any question that I haven’t narrowed down to 2 answers, or 3 answers and I have a strong hunch what the answer is. I think beyond that it just isn’t worth the risk.</p>
