When the screen said 770, I really thought it was a bug in the software. But, when the entire staff at Pearson Vue center came jumping for a glance at my score report, I realized that I had nailed it. I had earlier scored a modest 680 on GMAT, and there-on, such a huge jump with just 4 months of GMAT prep (alongside my job) could not have been possible without Experts’ excellent study material and continuous and personalized guidance. I also signed up for the Application Package and once again, Experts’ help was instrumental in securing a berth in Boston University School of Business and Goizueta Business School with full scholarships in each institution! A few of my friends already signed up on my recommendation. From my experience, I have no hesitation in claiming that when it comes to pursuing GMAT Prep and a subsequent B-School admission, Experts’ Global is the way to go. And by the way, it is very reasonably priced too! Swarnendu Rai, Moved from 680 on his first attempt to 770 on the GMAT. Made into Boston University and Goizueta Business School, Emory University with 100% scholarships!
