Dr. Sushma Jha..This name doesn't need a recommendation. But for all those who have just started looking for an english teacher for GMAT, I'd recommend a demo class with ma'am. Under her guidance, I scored 710 in GMAT. Studying and taking doubts with her always felt like discussing with a friend. One just need to follow what has been said in the class and GMAT english is no big deal. In addition to teaching, she keeps you motivated till the end. Moreover, she is available online too; a great advantage to the distant students. In the end, I want to express my gratitude towards her.
