Dear student,

Yes the income certificate is necessary during counseling process because the government fee weaver scheme eligibility depends on the total income of the family which is represented by the certificate issued by the government, but if you not have the certificate you can also choose to skip the it's submission but then you will not be able to get the advantages of the scheme offered by the government in respect to the course at the time of counseling.

The scholarships are not included as there forms are to be filled separately and you have to present the set of documents there too.

And, for the submission of the income certificate to college. They have a separate channel and they would be needing all the documents too but they will only verify the document not send it to the counseling authorities.
