Dear student,

There must be mistake in your caste certificate as in every type of counselling every university ask for only newly created certificate i.e. the certificates issued after April month of every year, so the possibility is that you have submitted an old certificate.

And as now you are a general candidate so your admission will be done on the basis of general candidate and according to that merit list will be prepared and you can take part in the counselling of DU as a general candidate.

Good Luck :)
