Hey!

See, SSC has strictly mentioned that they will not entertain any requests of editing the form, however candidates can edit the form twice within the duration of application process by logging onto their application and there is a tab of "modify", with which you can edit your basic details. And if you are not able to do so, also your application does not get rejected then you can write the exam. If they permit you to write the exam, then there are very low chances that  they will later on debar you.

Thankyou and lets hope for the best.
