You may be required to sit on an English Language Test such as IELTS or TOEFL before the university will confirm your seat on the course. The IELTS is organized by the British Council and results take 2-3 weeks.
The minimum scores usually required are 6.0 to 7.0 for IELTS and 213 to 250 (CBT) for TOEFL.
For MBA programs in good universities, a good GMAT score is required, in addition to IELTS or TOEFL scores and work experience of 2-3 years, in addition to decent academic performance at the Bachelor's level.
