You will have to be patient. One of the officials there will openly announce the score range that is permitted to enter the exam hall at that particular time, so listen attentively.
• After the arrangements, you will move in, but before you are been given your own computer, you will have to go through accreditation with your acknowledgment slip
• During the Accreditation,a passcode will be written on your acknowledgment slip by the official doing the accreditation.
• On getting to your computer, you will be required to input the passcode that was written on your acknowledgment slip during accreditation. Without that, you can’t log in
