The GMAT exam consists of four sections: An analytical writing assessment, integrated reasoning, the quantitative section, and the verbal section. Total testing time is three and a half hours, but test takers should plan for a total time of approximately four hours, with breaks.
The GMAT is offered most days of the year. This type of schedule allows you to complete your GMAT review at your own pace and take the exam when you determine that you're ready. Each GMAT testing center has its own schedule.
