As per my detail both GMAT and TOEFL entrance exams are present for taking admission for MBA. But the GMAT scores are accepted by all India universities and the TOEFL is an entrance for abroad institutes.

All international students whose native language is not English need to provide a TOEFL score as proof of English proficiency for university study.

A TOEFL score is accepted at over 9,000 colleges and universities in over 130 countries, including nearly every top university in the U.S., Canada and Australia.
