If you’re thinking of enrolling in graduate school to earn your MBA, it’s time to start thinking about preparing for the Graduate Management Admissions Test (GMAT). Working with a GMAT tutor is for many people a wise investment to help you strengthen the academic areas you may be weak in and improving your overall test score. A GMAT prep tutor should teach you not only the kind of information you need to know for the test, but the best test-taking strategies. The GMAT tests you on four categories: quantitative, verbal, integrated reasoning, and an analytical writing assessment. Cramming is probably not going to give you good results for this standardized test; give yourself between two and six months to prepare, focusing on your most challenging areas first. Successful GMAT prep means planning ahead and studying thoroughly. Those students who reported studying under 75 hours were more likely to score 400 or lower on the test, while students who studied 121 hours or more were more likely to score 700 or higher on the test. Hiring a GMAT prep tutor can range in price from under $50 to over $200 per hour.
