It is always good to reach atleast an hour before the exam. Due to Corona pandemic, social distancing and strict santisation measures mean, it will take relatively more time than normal for the security personnel to complete the security check and your Id validation. So if you reach just 30 minutes before the exam and there are quite a few Candidates before you standing in for the security check, it only adds to your pressure. So it is good if you can manage to be there atleast an hour before the scheduled time.
