Depending on what program you are looking at, the entry requirements will vary for international students.
You will need to make sure you have a good level of English understanding and you can do this by taking one of the following commonly accepted tests of English ability:
TOEFL - Test of English as a Foreign Language
IELTS - International English Language Testing System
For students applying for UG Degrees, IELTS can be waived off based on their English scores in 12th or A Levels. For PG applicants, at times IELTS can be waived off based on an interview that could be conducted at the Options Unlimited Offices.
