From the very beginning, Payal laid the foundation of e-GMAT's success by instilling a process-driven approach to GMAT preparation, becoming a Six Sigma aficionado who believes in "doing things right the first time. Her quantifiable impact speaks for itself: on GMAT Club—the largest online GMAT forum—she is ranked as the #1 rated GMAT expert globally, with e-GMAT maintaining over 1,800 reviews and Payal sustaining a 4.8/5 instructor rating as of 2024-25.
