Format of the GMAT Exam
The following is a diagram of the structure of the full GMAT exam. MBA programs typically required all 4 section scores. But Masters in Business and Masters in Management, or MiM, programs are interested to see only the Verbal and Quantitative results. Check with your school, so that you can better focus your study.

EU/UK-based Masters programs require scores from only two sections of the GMAT: the Quantitative and Verbal sections, and each is scored separately, on a scale out of 51, and then combined to make the famous headline score between 200 and 800. If you are applying for an MSc or Masters in business, or a the Masters in Management (MiM), then you can click right through the Integrated Reasoning and AWA sections.
A top-Twenty MBA program, however, still requires scores from all 4 sections. If you are applying for such a program, then you may like to think about how to optimize your study program, because these four sections are all very different from one another. For example, you may like to find the so-called "low-hanging fruit," and study that first.
