Preparing for the GMAT: How long should you study? Dustin Cornwell May 27, 2010 One of the questions our admissions team hears frequently from applicants is “How long should I study for the GMAT?” While there is no official consensus, we generally recommend that applicants start studying for the exam at least 4 weeks before their test date. The official GMAT blog on mba.com discusses the results of a survey of about 8,000 GMAT test takers. The survey looks at how much time students take to prepare for the exam as well as the correlation between test scores and study time.If you’re planning to take the GMAT, you may want to take a look at the results of the study and read the tips provided by Gregg Schoenfeld of the Graduate Management Admission Council.
