achieve their dream scores since 2010. 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.\u00a0 Her quantifiable impact speaks for itself: on GMAT Club\u2014the largest online GMAT forum\u2014she 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.\u00a0 Payal holds a Bachelor's degree in Chemical Engineering from the prestigious BITS Pilani and brings analytical rigor from her engineering career at Honeywell, where her experience managing complex projects\u2014including multi-million dollar NASA programs\u2014instilled the systematic precision she now applies to GMAT instruction.\u00a0 Her GMAT expertise spans across all sections of the test, with particular specialization in verbal sections where she pioneered her signature \"pre-thinking strategy\" for Critical Reasoning, while also introducing a novel framework of six core \"process skills\" for Quantitative reasoning and innovative approaches for the new Data Insights section that help students systematically tackle problems rather than relying on brute-force repetition.\u00a0 Passionate about education, Payal left her lucrative engineering career to pursue her vision of making quality GMAT preparation accessible to all, believing that students should \"give 200% or don't take on the task at all\"\u2014a philosophy that permeates every aspect of her teaching.\u00a0 Her success metrics speak volumes: e-GMAT delivers more 700+ scores than any other prep provider, with students consistently crediting her strategies for dramatic score improvements. She has authored over 2,000 GMAT practice questions, conducted 1,000+ hours of webinars, and regularly contributes strategic articles to the e-GMAT blog.\u00a0 \u00a0","sameAs":["https:\/\/e-gmat.com","linkedin.com\/in\/payal-tandon-9810512","https:\/\/www.youtube.com\/@egmat\/videos"],"url":"https:\/\/e-gmat.com\/blogs\/author\/payale-gmat-com\/"}]}},"_links":{"self":[{"href":"https:\/\/e-gmat.com\/blogs\/wp-json\/wp\/v2\/posts\/53751"}],"collection":[{"href":"https:\/\/e-gmat.com\/blogs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/e-gmat.com\/blogs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/e-gmat.com\/blogs\/wp-json\/wp\/v2\/users\/74405"}],"replies":[{"embeddable":true,"href":"https:\/\/e-gmat.com\/blogs\/wp-json\/wp\/v2\/comments?post=53751"}],"version-history":[{"count":3,"href":"https:\/\/e-gmat.com\/blogs\/wp-json\/wp\/v2\/posts\/53751\/revisions"}],"predecessor-version":[{"id":53758,"href":"https:\/\/e-gmat.com\/blogs\/wp-json\/wp\/v2\/posts\/53751\/revisions\/53758"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/e-gmat.com\/blogs\/wp-json\/wp\/v2\/media\/53754"}],"wp:attachment":[{"href":"https:\/\/e-gmat.com\/blogs\/wp-json\/wp\/v2\/media?parent=53751"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/e-gmat.com\/blogs\/wp-json\/wp\/v2\/categories?post=53751"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/e-gmat.com\/blogs\/wp-json\/wp\/v2\/tags?post=53751"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
