You didn't mentioned about which board or examination you are asking this question. See in general, such details can be edited while the correction options are given. I would recommend you to contact the helpdesk of the examination you are talking about, and get it discussed. They will give you the information.
Also you can repost this question with proper question specifics, so that we can understand and provide you all the information required as soon as possible.
Goodnight :-)
