Hello Divya,

SSC CGL examination involves biometrics and cross checking of documents and admit card at the examination venue and as the exams are going on now, Check once again and if there is a major change then you have to rush to the concerned regional office and get the things corrected. As per you said, your initials of second name is missing, may be it is ok but if this is wrong then do the needful quickly.

Check this FAQ document of SSC which i am attaching below, they have given instructions for all the problems.
