sir i had uploaded my friend's signature instead of mine and confirmation was also done + fee payment also then what should i do
Hii Shri!
You haven't mentioned the name of the entrance exam about which you are asking the question. Kindly specify the name of the exam. Also, if you uploaded the wrong details, you may contact the helpdesk of the respective examination and ask them about the same. Else, wait for the correction window to open and then re-upload the correct image.
Hope this helps.
Good luck!
