Hello aspirant,
I hope that you are doing well. Yes you can take admission in delhi if you have done your 10th or 12th from Delhi but you cannot use st caste certificate in delhi quota as you have domicile of rajasthan then the st category quota will be applicable in rajasthan state only.
Or else you can take admission through 15% AIQ.
