I want to do my 12th from nios.does it make a difference if I register directly from website or select a study centre in Delhi for Jac delhi quota. Also I am a resident of Delhi

Yes, it makes a significant difference . To secure the 85% Delhi Home State Quota in JAC Delhi, your NIOS study centre or regional centre must be located in Delhi . Registering directly online with a Delhi address and choosing a Delhi Study Centre is recommended to ensure your records reflect the Delhi region.
