新GRE官方指南名师解读

新版OG里面ETS详细解释了语文与数学部分的评分原理。有几个细节特别值得考生注意：

　　1）明确了加试部分的题会影响你的得分。原文如下：

　　For the Verbal Reasoning and Quantitative Reasoning measures of the computer-based GRE revised General Test, the reported scores are based on the number of correct responses to the questions included in the operational sections of the measure.

　　注：加试部分会影响你的得分，在此范亚飞老师提醒考G的同学注意，加试，即使是经典加试也得做。否则会影响你的得分。

　　2）解释了部分自适应的意思。你最终的得分和两个核心因素有关：一、做对题目的个数 二、每个部分的难度值

　　The Verbal Reasoning and Quantitative Reasoning measures are section-level adap- tive. This means the computer selects the second section of a measure based on your performance on the first section. Within each section, all questions contribute equally to the final score. For each of the two measures, a raw score is computed. The raw score is the number of questions you answered correctly.

　　The raw score is then converted to a scaled score through a process known as equating. The equating process accounts for minor variations in difficulty from test to test as well as the differences introduced by the section-level adaptation. Thus a given scaled score for a particular measure reflects the same level of performance regardless of which second section was selected and when the test was taken.
