The SAT's scoring system is kind of hard to understand. Every time you get a question right, you get a point. Every time you miss one (ANSWER INCORRECTLY NOT LEAVE BLANK) you get 1/4 a point taken away. If you leave a question blank you receive no points, but you don't lose any either. ---------------------------- You can leave questions blank on the SAT. Just like the other person said, Correct answer = 1 pt Incorrect answer = -1/4 pt Blank = 0 pt The test is made so that the expected value from randomly guessing is 0. If you are unsure of a question and can eliminate a few answer choices, it's probably a good idea to guess. On a math grid-in question, however, you do not get penalized for wrong answers, so never leave those questions blank (at least guess if you have no idea).
