The GMAT is the Graduate Management Admissions Test used by graduate business schools around the world to help them select new students. The test is the property of the Graduate Management Admission Council (GMAC), the body that writes and administers the test. The GMAT includes a quantitative section. Mathematical inequality expressions are part of that section. They are sometimes called GMAT inequalities.

The GMAT exam is structured into three distinct sections. The first deals with analytical writing. The second test quantitative ability, and assumes high school mathematics knowledge, no greater. The third section of the GMAT tests verbal skills. Three and one half hours is allowed for the total GMAT. An optional ten minute rest period is allowed between both the second and the third sessions. The GMAT is conducted within a formal test center in a supervised environment.

The quant section has thirty seven questions. About twenty two of those questions deal with problem solving. Most inequality type questions will occur in the problem solving section. Another fifteen questions deal with data sufficiency.

When it was first introduced decades ago, the GMAT was a paper-based assessment. Computer technology has allowed increased sophistication. Now the test is computer-adaptive. Students sit at a computer in a supervised test center. The test allows for question difficulty to adapt based upon the real time performance of the student.

If a student, for example, solves two or more questions successfully, the third question posed by the computer-based test may be more difficult. This adaptive technique is subsequently reflected in scoring the test.

To assist students, the authors of the GMAT publish The Official Guide for GMAT Review. This is an encyclopedic text spanning about 830 pages. It is aimed at providing a thorough understanding of the format of the GMAT as well as the content tested. An exclusive feature the Official Guide is that it is the only source of actual past GMAT questions as well as their answers. In fact the book includes more than 800 past GMAT questions and their answers.

The Official Guide divides into ten sections; what is the GMAT, how to prepare, diagnostic test, math review, problem solving, data sufficiency, reading comprehension, critical reasoning, sentence correction, and analytical writing assessment.

The twelfth edition of the Official Guide contains a total of 404 quantitative questions, including 230 questions in its problem solving section and 174 questions in its data sufficiency section. The book will help students get on top of handling GMAT inequalities.
