Uses of gmat exam
   
Reliability and validity:
The GMAT exam is a reliable, valid measure of skills found to be important in graduate management study. In repeat research studies, GMAT scores have been found to be an accurate predictor of academic success in the first year of an MBA and  other graduate management program.
Standard measurement:
 GMAT scores provide the same standard for evaluating all test takers. That's why you can feel confident making direct comparisons among applicants' GMAT scores.
Exam formats or sections

Verbal section

The verbal section of the GMAT Exam measures the ability to read and comprehend written material, reason and evaluate arguments and correct written material to express ideas effectively in standard written English. The question types are reading comprehension, critical reasoning, and sentence correction questions. Scores range from 0 to 60, although they only report scores between 11 and 51.
Reading comprehension passages are up to 350 words long. Topics contain material from the social sciences, physical or biological sciences, and business-related areas (marketing, economics, human resource management, etc.). Reading comprehension passages are accompanied by interpretive, applied, and inferential questions.

Quantitative section

The quantitative section of the GMAT measures the ability to reason quantitatively, solve quantitative problems, and interpret graphic data.
Questions require knowledge of arithmetic, elementary algebra and commonly known concepts of geometry.
There are two types of quantitative questions: problem solving and data sufficiency.
Scores range from 0 to 60, although they only report scores between 11 and 51.
Problem solving questions are designed to test the ability to reason quantitatively and solve quantitative problems.
Data sufficiency questions are designed to measure the ability to analyze a quantitative problem, recognize which data are relevant and determine at what point there is enough data to solve a problem.

 This section measures the following abilities:
    Understanding words and statements in reading passages
    Understanding the logical relationships between significant points and concepts in the reading passages
    Drawing inferences from facts and statements in the reading passages
    Understanding and following the development of quantitative concepts as they are presented in verbal material
Critical reasoning questions are designed to test the reasoning skills involved in making arguments, evaluating arguments, and formulating or evaluating a plan of action. Questions are based on materials from a variety of sources.
This section measures the following abilities:
    Argument construction
    Argument evaluation
    Formulating and evaluating a plan of action
Sentence Correction questions ask which of the five choices best expresses an idea or relationship. The questions require familiarity with the stylistic conventions and grammatical rules of standard written English. This section measures the following abilities:

•     Correct expression
•     Effective expression

Analytical writing assessment

The AWA consists of one 30-minute writing task
analysis of an argument.
It is important to be able to analyze the reasoning behind a given argument and write a critique of that argument.

The essay will be given two independent ratings, one of which may be performed by an automated essay-scoring engine.
The automated essay-scoring engine is an electronic system that evaluates more than 50 structural and linguistic features, including organization of ideas, syntactic variety, and topical analysis. If the two ratings differ by more than one point, another evaluation by an expert reader is required to resolve the discrepancy and determine the final score.

The analytical writing assessment is graded on a scale of 1 (the minimum) to 6 (the maximum) in half-point intervals (a score of zero means the answer was gibberish or obviously not written on the assigned topic):

•     An essay that is deficient.
•     An essay that is flawed.
•     An essay that is limited.
•     An essay that is adequate.
•     An essay that is strong.  
•     An essay that is outstanding.

Total score
The total score ranges from 200 to 800 and measures performance on the quantitative and verbal sections (performance on the AWA and IR sections do not count toward the total score.)
The score distribution resembles a bell curve with a standard deviation of approximately 100 points, meaning that 68% of examinees score between 400 and 600.

Integrated reasoning
Integrated reasoning is a new section designed to measure a test taker’s ability to evaluate data presented in multiple formats from multiple sources.
The skills being tested by the integrated reasoning section were identified in a survey of 740 management faculty worldwide as important for today’s incoming students. The integrated reasoning section consists of 12 questions in four different formats: graphics interpretation,
 two-part analysis
 table analysis,
 and multi-source reasoning.
 Integrated reasoning scores range from Like the AWA, this section is scored separately from the quantitative and verbal section. Performance on IR and AWA do not contribute to the total GMAT score.
The integrated reasoning section includes four question types: table analysis,
 graphics interpretation,
multi-source reasoning,
 and two-part analysis.
 In the table analysis section, test takers are presented with a sortable table of information, similar to a spreadsheet, which has to be analyzed.
Each question will have several statements with opposite-answer options (e.g., true/false, yes/no), and test takers click on the correct option.
Graphics interpretation questions ask test takers to interpret a graph or graphical image.
 Each question has fill-in-the-blank statements with pull-down menus; test takers must choose the options that make the statements accurate.
Multi-source reasoning questions are accompanied by two to three sources of information presented on tabbed pages.
Test takers click on the tabs and examine all the relevant information, which may be a combination of text, charts, and tables to answer either traditional multiple-choice or opposite-answer (e.g., yes/no, true/false) questions.
Two-part analysis questions involve two components for a solution. Possible answers are given in a table format with a column for each component and rows with possible options. Test takers have to choose one response per column.

The final score is not based solely on the last question the examinee answers (i.e. the level of difficulty of questions reached through the computer adaptive presentation of questions).
The algorithm used to build a score is more complicated than that. The examinee can make a mistake and answer incorrectly and the computer will recognize that item as an anomaly.
If the examinee misses the first question his score will not necessarily fall in the bottom half of the range.
All scores and cancellations in the past five years will be on a student's score report, a change from the previous policy of the last three scores and cancellations being kept on the score report.
