<p>My first test that I took, I omitted the answers to questions I didn't know / was unsure about and got a 1930. I don't know if I should try to answer most, if not all, of the questions this time around, because I don't know how that might affect my score.</p>
<p>You basically get 2 guesses for free because even if you get them wrong you only lose a 1/2 point and that is rounded in your favor. If you find yourself guessing at 3 (-0.75) or more then you might as well guess at up to 6 (-1.5) since they both will round to the same result of -1 off your score.</p>
<p>depends !ON WR,always guess because you can always eliminate many answer choices.
On Math - a bit pointless
On CR - if you narrow down the options to two, guess</p>
