The Test

The exam measures verbal, mathematical and analytical writing skills that the examinee has developed over a long period of time in his/her education and work. Test takers are given 3.5 hours to answer questions in each of the three tested areas, and there are also two 10-minute breaks[2]; in general, the test takes about four hours to complete.

Scores are valid for five years (at most institutions) from the date the test taker sits for the exam until the date of matriculation (i.e. acceptance, not until the date of application).

The maximum score that can be achieved on the exam is 800. Over the past 3 years, the mean score has been 535.2.[3]

The Analytical Writing Assessment (AWA) section is the first section to be answered. Then the Quantitative section and the Verbal Ability section follow respectively.

Quantitative Section

The quantitative section consists of 37 multiple choice questions, which must be answered within 75 minutes. There are two types of questions: problem solving and data sufficiency. The quantitative section is scored from 0 to 60 points. Over the past 3 years, the mean score has been 35.6/60; scores above 50 and below 7 are rare.

Problem Solving

This tests the quantitative reasoning ability. Problem-solving questions present multiple-choice problems in arithmetic, basic algebra, and elementary geometry. The task is to solve the problems and choose the correct answer from among five answer choices. Some problems will be plain mathematical calculations; the rest will be presented as real life word problems that will require mathematical solutions.

Numbers: All numbers used are real numbers.
Figures: The diagrams and figures that accompany these questions are for the purpose of providing useful information in answering the questions. Unless it is stated that a specific figure is not drawn to scale, the diagrams and figures are drawn as accurately as possible. All figures are in a plane unless otherwise indicated.

Data Sufficiency

This tests the quantitative reasoning ability using an unusual set of directions. The examinee is given a question with two associated statements that provide information that might be useful in answering the question. The examinee must then determine whether either statement alone is sufficient to answer the question; whether both are needed to answer the question; or whether there is not enough information given to answer the question.

Data sufficiency is a unique type of math question created especially for the GMAT. Each item consists of the questions itself followed by two numbered statements.

(A) If statement 1 alone is sufficient to answer the question, but statement 2 alone is not sufficient.
(B) If statement 2 alone is sufficient to answer the question, but statement 1 alone is not sufficient.
(C) If both statements together are needed to answer the question, but neither statement alone is sufficient.
(D) If either statement by itself is sufficient to answer the question.
(E) If not enough facts are given to answer the question.

Perhaps the easiest way to fully internalize the scope of these questions is to replace the word “is” with the words “must be” – the questions are not asking whether an answer is possible, but rather, whether it "must" be the case.

Analytical Writing Assessment

The Analytical Writing Assessment (AWA) section of the test consists of two essays. In the first, the student must analyze an argument and in the second the student must analyze an issue. Each essay must be written within 30 minutes and is scored on a scale of 0-6. The essay is read by two readers who each mark the essay with a grade from 0-6, in 0.5 point increments with a mean score of 4.1. If the two scores are within one point of each other, they are averaged. If there is more than one point difference, the essays are read by a third reader.[6]

The first reader is Intellimetric, a proprietary computer program developed by Vantage Learning, which analyzes creative writing and syntax of more than 50 linguistic and structural features.[7] The second and third readers are humans, who evaluate the quality of the examinee's ideas and his or her ability to organize, develop and express ideas with relevant support. While mastery of the conventions of written English factor into scoring, minor errors are expected, and evaluators are trained to be sensitive to examinees whose first language is not English.[6]

Each of the two essays in the Analytical Writing part of the test is graded on a scale of 0 (the minimum) to 6 (the maximum):

  • 0 An essay that is totally illegible or obviously not written on the assigned topic.
  • 1 An essay that is fundamentally deficient.
  • 2 An essay that is seriously flawed.
  • 3 An essay that is seriously limited.
  • 4 An essay that is merely adequate.
  • 5 An essay that is strong.
  • 6 An essay that is outstanding.
