Thanks for detailed description. I had already seen the details in the email. My main query is can we choose our own dates or do we have to go with one of the date given by them? Have u done the process of changing the date?In the pdf they emailed you there is a “request a new appointment” button , they need you name , email address, your paper number ( top if the email they sent you) , and ask the reason ( im away because of a family medical situation) and ask you to choose 3 dates between september and november ( it is all explained in the email) , they review the dates , select one and send you another email.
