Raw Score and Scaled Score for the Critical Reading, Writing, and Math sections
Your raw score for each section is calculated by adding one point for every question you answered correctly and subtracting ¼ point for every question you answered incorrectly. Questions left blank do not affect your raw score (you essentially get zero points for unanswered questions). Your raw scores for the three Critical Reading, three Writing, and three Math sections that counted are added up to produce three final raw scores, one each for Critical Reading, Writing, and Math. The Experimental Section is not graded and has no effect on your final score.
These three raw scores are then converted into three scaled scores, which range from a minimum of 200 points to a maximum of 800 points, and are reported in 10 point increments (so possible scores include 520 or 700, for example, but not 524 or 705).
