Hello Rahul,

No need to worry. 

The exam conducting authority will provide the correction facility which can be done through online mode. 

You have to log in on the official website for correction. Then you can edit and re-uploaded the images as per the given specification by the authority.

The status of basic registration will be published on 7th January 2019. The correction facility will be started from 8th January 2019. The corrections can be done till 18th January 2019.

Hope this helps.
