HELLO SIR ,

NO it is not necessary to have IT subject only to apply for C.S for b.tech,

but sometimes they may ask you about your vocational subject ,

so if you can keep I.T as a subject do keep it.

It will also help you in further studies if you are applying for C.S .

IT IS A SCORING SUBJECT.

ALL THE BEST

HOPE THIS HELP

THANK YOU

*ASK IF YOU HAVE ANYMORE QUERIES
