See this mistake changes entirely the name of your Mother. So it will create a problem. Now you can do a thing, you can contact the exam conducting board and ask them if there are any procedure available to change the name they can suggest you some information. As you said SSC , its confusing as there are two ssc such as Staff Selection Commission or Maha SSC. So I would recommend you to type the SSC (full form) contact us details on google search and then contact the authority, this can provide you some solution (if there are any procedure).

I hope this answer helps. All the very best for your future endeavors!
