Do I need to give any English proficiency test?

<p>I am doing BBA from Amity Global Business School, Kolkata in India. Whatever the professors teach here is in English. I am planning to apply to some MBA programs for college seniors like the HBS 2+2 program and Yale Silver Scholar program and also to business schools like the Stanford Global School of Business which consider applications sent by college seniors. These universities have mentioned in their websites that they do not require an English proficiency test if the mode of instruction in the undergradute college is English. Would there be any need for me to give any of those exams?</p>
