IELTS has an online registration system. One can also submit a print of the registration form at the nearest IELTS IDP or IELTS British Council center. While the pen and paper mode has a selective number of dates, the computer-delivered IELTS has a substantial number of them. For both formats, it is necessary to book the test date in advance on the IELTS IDP or IELTS British Council websites. Remember, a passport is mandatory for registration as you have to present it as ID proof. As of March 2022, the IELTS exam fee is Rs. 14,700.
