can we change the center of examination now
Whether you can change your center now it depends upon the time when you wanted to change it if the deadline has already passed off editing your documents and information on the website, then it's quite difficult to change your center because most entrance exams have a fixed window during the application and you can only edit it within a specific time. If the period is over, you usually can't change as you won't be allowed to do so. but I would recommend that you go to official website or contact the exam help department, they might consider your request and if you provide valid reason then you will be able to change your examination center.
Changing the examination center after the application process is usually not allowed. However, in some cases, if there is a genuine reason, such as illness or emergency, you may request a change. You will need to contact the exam conducting authority or board and follow their guidelines for such requests. Make sure to check the official website or contact their helpdesk for specific instructions. It’s best to apply as early as possible to avoid last-minute issues.
