Hi aspirant,

For appearing in CSAB counselling, one needs to fulfill the below mentioned criteria:

• Candidates should have a valid JEE Main rank.
• The JoSAA 2021 eligibility criteria have to be met by candidates.
• Those candidates who participated in JoSAA 2021 but who were not allotted any seat will be eligible for CSAB 2021 special round.
• It should be noted that those candidates who opted not to participate in the special round after JoSAA will not be eligible for CSAB 2021 special round admission procedure.
• Candidates who are allotted seats through JoSAA 2021 but did not accept or cancelled the e allotted seat will also be eligible for CSAB 2021 special round.

Since you have accepted the seat and even paid the partial fee, you can not participate in CSAB counselling.

Hope it helps!!
