IELTS

Are you talking about General IELTS or Academic IELTS?

Any one from each.

For MBA you have to give GMAT first of all with a minimum 3 year work experience and after that minimum band score is 6 or 6.5. Work hard to achieve these score .

Dear Hemant, alongwith average colleges there are a few top universities too. Remember admission depends on the student's overall profile. Check University of Chicago Booth, UCLA, Babson College, Bentley, Boston University etc.

Hello Mohd
You Need minimum 5.5 IELTS score to get student visa for Australia

Dear Shaunak, no accredited university will grant you admission without a GMAT and work experience. Therefore you will be required to take the GMAT.

Australia is best.

Why not? You surely can.

Dear Divya,
ILETS is a English proficiency test, taken for admission abroad, all the universities requires ILETS/TOEFL score for candidates from a country where English is not first language or native language. Proficiency is rated on scale of 10 now requirement varies from university to university.
All the very best.

Dear Mayur, have you checked with the requirements of the universities you desire to apply to? normally a score of 5 is not acceptable but might be considered under certain circumstances depending on your profile overall. An IELTS of 6.5 ( with no section less than 6 ) is required mostly.
