Dear Nidhi, IELTS is a Language proficiency test taken for checking your Listening, Reading, Writing and Speaking skills as we are non Native English Speakers. IELTS has no eligibility criteria. You can take it irrespective of your Educational qualification and aggregate in your Graduation. So IELTS has got nothing to do with your previous studies. But you need to score a minimum band of 7.5 or more for admission in a decent University.
