Most universities require either GMAT or GRE scores for graduate degree admissions. Getting accepted into a university of your choice or to receive a scholarship, you are usually required to submit your GMAT or GRE scores. Both tests evaluate your ability in quantitative reasoning, critical reasoning and analytical writing. Before taking the tests, it is a good idea to closely familiarize yourself with the exam structure, content and the location where the test will be held. It is also very important to plan well ahead, so that you have enough time to prepare, to take the test and apply for your graduate course.
