A. It is upto you when you wish to take the test. No fixed time has been set for appearing for the same. Day or night - the choice is yours. Select what suits your interest best and is convenient. Just make sure that your internet connection is reliable and the speed is decent. However, as the test around an hour to get finished, one needs to stay focused and alert throughout the test's duration. If you're not a night person and easily get tired at that time of the day, it is always a good idea to attempt the test in the morning when you're wide awake and fresh.
