Re: SAT question

So guessing randomly won't help, but if you can narrow it down to 2-3 guessing is +EV.

These are 5 choice questions.
As a poker player you should understand there is a definite line to draw where it +EV.
Guessing randomly is EV=0. Eliminating just one answer results in a random guess having positive EV. You don't have to "narrow it down to 2 or 3" to gain by guessing. If you can estimate the probability of any one choice being the correct answer to be less than 20%, you gain by randomly guessing one of the other 4.

it's true. you lose 1/4 point for incorrect answers though. but dont worry all that is explained in detail by the proctor/directionms

It being explained by the proctor wasn't sufficient, as the OP has taken the test once and clearly does not understand how it works.
