Total scores incorporate performance on the Quantitative and Verbal sections and range from 200-800, in 10-point increments. The Total score is not a simple sum of the Verbal and Quantitative scores.
This is not to imply that the Quantitative and Verbal scores (6-51) somehow add up to the Total score (200-800); a completely different scale is used to express the Total score.
