Hello Student

If you want to correct your surname in the SSC admit card or marksheet or in the both then you have to apply to the respective board authority submitting with the application the valid documents in favour of your or in support of your changing or correction of surname. Better if you submit a first class magistrate avidabit copy with your application to the respective board for changing your surname in the SSC marksheet and admit card both. But it will take time. Whether you attempt for the next term of EAMCET exam or year to give in up the exam for this time.

Hope this helps.
