Hi Hima!

Yes, a girl can wear kurti which has flower print on it for AIIMS exam. AIIMS has not prescribed any dress code for this year. But make sure that your kuti does not contain any kind of badge , broche , clip or anything ornamental or anything bulging. This will make checking staff to suspect you.

Make sure your kuti only has print on it and nothing else. 

In the declaration of admit card , just enter the present date and present place. After printing , it will show date and time of printing of the admit card at the footer.

All the Best for your exam!
