Dear Charu, IELTS and TOEFL are both Language proficiency tests. However few Universities accept TOEFL while few others accept IELTS. So it entirely depends on the country that you wish to study in and the University you have chosen. So once you decide upon a University, you have to chrck their official website to see which scores they accept and proceed further.
