GMAT scores are essential for business school admissions. Unfortunately, taking the GMAT is challenging and takes significant preparation. Furthermore, failure to reach your desired score on your first attempt requires paying $250 more each time you retake it; to prevent this scenario from arising make sure to register more than seven days early!
There are various test-prep companies available, including Kaplan and Manhattan Prep. Both provide comprehensive programs with access to videos, practice problems and instructor guidance as well as offering free practice tests to give an indication of how well you might do on an actual exam.
GMAT includes an essay section to give business schools an indication of your writing skills. Additionally, there will be integrated reasoning (IR) questions which require logic in interpreting charts and graphs.
