Hi

Where it is written?..The candidature is provisional until you give the exam, clear it and until the seat is allocated it has nothing do with you appearing for the exams it is written in every admit card i presume. In this case the admit card you downloaded from the website is provisional meaning the original admit card will be issued against this admit card after verifying your identity at the exam center. So make sure you take your identity documents they mentioned and the downloaded admit card along with you.

All the best!
