Leave blank or guess??

“(Leaving 8 blank = -2 points, and getting 2 right would = +2 points.)”

i think you mean guessing on 8

i always guess, unless i can’t even eliminate 1 which never happens

the way it works that if you guess, the mathematical probability that you get it right is 1/5. therefore, if you randomly guess on 5 questions, you are supposed to get 1 right. so to negate that, collegeboard deducts .25 per question so that in that same set of 5 questions you don’t gain any points.

now, if you can get it down to 4 choices, you will guess 1 of every 4 questions right. therefore, you will +1 for the one you were supposed to get right, and -.75 for the ones you were supposed to get wrong. this is a net gain of +.25…if you leave a lot empty those quaters of a point can really start to add up and boost your score a touch so you can get slightly better scores.

so, my general rule is guess on all of them–chances are its an educated guess and it is better than a 20% chance at getting it right ;)
