Hello Ramgopal,

Karnataka Examinations Authority (KEA) has released the official schedule for uploading documents that are required for the counselling.

It is compulsory to have Study Certificate from the school of both Xth and XIIth standard and it is not important to have Income certificate but it is better to have backup so have your income Certificate with you.

Best of luck for what you need.

I hope this helps you out, if you have any other query, please let us know,
Till then stay home and stay safe.
