How Are GRE Scores Calculated and When Are They reported?

On both the verbal and quantitative sections of the GRE

 1.your raw score=number of questions you answered correctly,adjusted for the difficulty level of those questions.

  2.Each raw score is then adjusted to a scaled score
     (which lies b/w 130-170).

  3.The written score report that you will receive in the mail will include both  your scaled scores and your percentile rank indicating the percent of examinees scoring below your scaled scores on the General Test.

Your analytical writing score will be the average of the scores assigned to your essays by 2 trained readers.These scores are rounded up to the nearest half-point.Your combined analytical writing score can vary from 0-6,with 6 the highest score possible.

As soon as you have finished taking the test, the computer will calculate your unofficial scaled scores for the verbal and quantitative sections and display them to you on the screen.You should receive in the mail an official report containing all three scores(awa+verbal+quant) approximately 3 weeks after the test date.
