GMAC官方关于CAT的计分标准解答

虽然看了置顶帖的谣言解答，但是本着实事求是的原则，还是给GMAC发了一封邮件咨询，回复的全文如下：The CAT will only determine your score by the correct or incorrect answer you’ve selected. It does not grade or affect your score in anyway by the time you take to answer the question. The GMAT® Total score is not the sum of the GMAT Quantitative and Verbal scaled scores. Rather, the GMAT Total is a rounded scale score derived from the sum of intermediate Quantitative and Verbal scores. Similarly, the reported Quantitative and Verbal scores are rounded scale scores derived from intermediate scores. Scale scores have the same meaning over time and permit schools to compute averages and other statistics. Because the scale scores are rounded to the nearest whole number, each scale score corresponds to a range of intermediate scores.

中间说的intermediate score不是特别理解，猜测是你那次考试的所有考生的平均水平作为基准点，say，550分，然后对比你的情况进行浮动，从而保证评分的公平。
或者以上就是percentile的意思，因为它参考了所有人水平，但是我想他是说总分（680）是在550基础上加的。
