After you are given the key string, you are to enter it in the slot provided below to access the test pages. In next few screens, your necessary personal details will be collected, and instructions for the test will be given. Please go through these steps carefully without committing errors in typing vital information like Roll No. or email address. There is no hurry because the actual duration of 45 minutes of the test starts after all these preliminary steps are over, when questions start appearing on screen, and starting a few minutes earlier or later will have no effect on your performance in the test either way.
