1.	A Quantitative score reported on a 200-800 score scale, in 10-point increments
2.	A Verbal score reported on a 200-800 score scale, in 10-point increments
3.	An Analytical Writing score reported on a 0-6 score scale, in half-point increments

Each of these three sections will be discussed at length below, but before we examine the sections individually, let us first discuss the computer-adaptive nature of the GRE. Because the GRE is administered on a computer (as opposed to the more traditional paper-and-pencil format), the test exhibits certain unique characteristics. For instance, only one question at a time is presented, the order of questions is not predetermined, and the test actually responds to your answers and shapes the test in order to most efficiently arrive at your proper score.

The test makers give the following description of the computer-based GRE: “The verbal and quantitative sections of the computer-based General Test are adaptive, which means that the selection of questions is tailored to an examinee’s ability level in each of the measures. Initially, an examinee is presented with a question of about average difficulty. Thereafter, the computer selects questions based upon (1) the statistical characteristics of those questions already answered (including the difficulty level), (2) the required variety of question types, and (3) appropriate coverage of content. The computer-based test format does not require test takers to be familiar with computers; a tutorial section at the beginning of the computer-based test teaches the test taker how to use the testing system.”

In other words, the first question in the Verbal or Quantitative section will be a medium difficulty question. If answered correctly, the computer will supply a somewhat harder question on the assumption that your score is somewhere above that level. If this next question is answered correctly, the following question will again be more difficult. This process continues until a question is missed. At that point, the test will supply a somewhat easier question as it tries to determine if you have reached your score “ceiling.” By increasing or decreasing the difficulty of the questions based on prior response, the test attempts to quickly pinpoint your appropriate score level and then confirm that level. Consequently, the first several questions are used to broadly establish your general scoring range, whereas later questions serve to affirm and pinpoint a specific score:

In the diagram above, correct responses to the first several questions lead to significant jumps in score, whereas later questions make smaller adjustments. A strong beginning followed by a weak finish will produce a higher score than a weak beginning followed by a strong finish. For this reason, your performance early in each section must be as strong as possible, even if this requires using more than the average time allotted per question.

The Quantitative Section
As outlined by ETS, “The quantitative section measures your basic mathematical skills, your understanding of elementary mathematical concepts, and your ability to reason quantitatively and solve problems in a quantitative setting. There is a balance of questions requiring arithmetic, algebra, geometry, and data analysis. These are content areas usually studied in high school.” Your performance on the 28 questions in the Quantitative section is used to determine a score from 200-800, with scores assigned in 10-point increments.

The Verbal Section
The test makers describe the Verbal section as, “The verbal section measures your ability to analyze and evaluate written material and synthesize information obtained from it, to analyze relationships among component parts of sentences, to recognize relationships between words and concepts, and to reason with words in solving problems. There is a balance of passages across different subject matter areas: humanities, social sciences, and natural sciences.” As with the Quantitative section, the Verbal section has its own individual scoring scale ranging from 200-800, and your score on the Verbal section combined with your score from the Quantitative section results in your overall score out of a possible 1600.

While examining the GRE scoring scales it is important not to lose sight of what the scores actually represent. Each score places a student in a certain relative position compared to other test takers. These relative positions are represented through a percentile that correlates to each score and indicates where the test taker falls in the overall pool of test takers. Because the Quantitative and Verbal sections are so divergent with respect to their content and difficulty, score percentiles are assigned to each section individually, and not to the combined score taken as the sum of both sections. The percentile ranking is critical since it is a true indicator of your positioning relative to other test takers, and, consequently, other graduate school applicants.

Based on the percentile rankings at the various scoring levels, it is evident that the Verbal section is markedly more difficult than the Quantitative section for the average test taker. Consider a student who scores a 720 in both sections. A 720 in the Verbal section would place this test taker ahead of 98% of his or her fellow applicants (roughly equivalent to an A or even an A+ by collegiate standards), whereas a 720 on the Quantitative section is only sufficient to place a test taker ahead of 74% of his or her fellow applicants (while a score in the 74th percentile is certainly excellent, it is by no means equivalent to a score in the 98th percentile). The mean scores for the two section further illustrate this trend, as the average for the Quantitative (591) is 122 points higher than the average Verbal score (469). Even a perfect Quantitative score (800) is achieved more frequently among test takers than a Verbal score as low as 660 (it is theoretically easier to score up to 140 points higher on the Quantitative section than the Verbal section at these scoring levels).
