Guess aggressively. There is a guessing penalty; it works as follows: there are 5 choices. For each answer right, you get one point, for each answer wrong, you lose ¼ point, and for each answer left blank, you neither gain nor lose. It protects against random guessing because, if you guess on 5 questions, statistically you’ll average 1 right and four wrong, and they cancel each other out. But that’s random guessing. Statistically, if you can eliminate even one choice as definitely wrong, you up your chances and make a net gain. Especially if you can narrow it down to two choices. Heads you get a dollar, tails you lose a quarter – good deal, right?
I’m a pro at standardized tests, do what I do and guess aggressively, don’t let that penalty scare you!
Also, the SAT is sooooo frickin LONG and you’ll be tired by the end. Bring a small snack and something to drink. You’ll have breaks during which you can eat and go to the bathroom.
