Advantage Testing GMAT Q&A

Because it takes time to learn all of the underlying math, reading, logic, grammar, and writing concepts and to practice applying them on timed practice tests, we recommend that students prepare for the GMAT with study sessions, tutoring, and timed practice testing multiple times per week for several months. 

When you plan your preparation schedule, also keep in mind that you may want to retake the GMAT. We recommend that most students begin preparing for the GMAT up to a year in advance of their application deadlines. This approach gives students ample time to prepare for the test and retake it if necessary, while allowing for sufficient time to finish the other components of business school applications.
