Dear Applicant,

I hope you are doing well. It's nice to see you engaging yourself in the army, to help our country.

About your question, you dont get an extra Mark's in the MNS Exam if you have a relation certificate. Relation certificate will only help you to give a higher chance of getting recruited. Only students who have taken NCC in theirs schooling or college get additional Mark's otherwise no.

Hope this helps...

I wish you good luck.

Try your best ok!!
