Hello Shivani!

If you want to know when your re exam will be and where it will be you must specify the exam name atleast so that I can provide you exact information.

Still no worries you can check it by going to exam website, login there, if you would have applied for re exam then you must download a new admit card which will definitely have details like date, time and place where exam will take place.

If the procedure for application was offline then you must visit to the respective authority for getting admit card offline and then check the requisite details.

Hope it helped you !
