Meet The Top Instructors

Payal Tandon


“If you take on a task, give it your 200%, or else don’t take that task on at all”. This is what Payal often tells her students, her team members, and even her daughter.

A perfectionist to the core, she gives everything her best without cutting any corners. No wonder she has been a topper throughout her academics. She was the topper (the absolute topper, not just 99 percentile) in the 12th grade State of Haryana board exam taken by more than 1 million people.

Pursing her passion of making learning effective and enjoyable, Payal is constantly thinking of better ways to impart skills to people – whether it is how to read a passage more efficiently, how to deconstruct a sentence, or how to train other experts. At e-GMAT, Payal oversees curriculum development, expert training, and all operational activities. In a nutshell, she is committed to the success of all e-GMAT-ers.

Rajat Sadana


Rajat mastered the skill of taking standardized tests at an early age by scoring better than 99 percentile on most exams including the CET (Indian equivalent of SAT), GATE (Indian equivalent of GRE including technical GRE), and the GMAT. Rajat stands out as one of the two students in the country who were selected by Nokia Research (NRC) Germany for a fully funded Master’s degree at IIT Delhi and subsequent internship at NRC Germany.

Post MBA (from Babson where he received full fellowship), Rajat was hired by Honeywell as a Marketing and Business Development Manager to grow its wireless business. During his 4 years at Honeywell, he helped grow the business from $2M to $25M. In August 2010, Rajat founded e-GMAT with Payal Tandon to fulfill his dream to democratize Test Prep education by leveraging technology to provide high quality, personalized, and effective education at affordable prices.

Japinder Kaur


Japinder is a person who believes in hard work, and in making an effort to stay true to her heart and passion.

A graduate from the Indian School of Business, one of the best B-schools in India and among the top 40 schools worldwide, Japinder has been a straight-A student throughout her academic career. She has also scored 760/800 in the GMAT and 1560/1600 in the GRE, both in her first attempts.

An avid reader from her childhood, she dreamt of being a writer one day. She feels proud of making it happen. Her book Vocabulary Advantage has been published by Pearson and teaches difficult English vocabulary creatively- through a combination of stories and etymology.

At e-GMAT, she is responsible for developing the Quant course for GMAT students and is loving the comeback of the same rush of thrill and creative excitement that she felt while working on her book and her venture.

Krishna Chaitanya


Krishna is a graduate from BITS Pilani, Hyderabad and has always been a consistent topper in many aptitude exams. His most recent achievement is 760 on GMAT including a perfect 51 in Quant. He also scored a 99.90 percentile in CAT, considered the Indian equivalent of GMAT and one of the toughest management entrance exams in the World, and a 99.94 percentile on XAT, one of the toughest management entrance exams in Asia.

He has always believed that every person is equally capable of learning and that it is only the opportunities and surroundings that affect a person’s capacity to learn. With the best GMAT verbal experts as his colleagues, Krishna considers e-GMAT as the ideal platform for him to be one of the best instructors in the world.
