dear aspirant,

First of all,be clear that spot round is not conducted by Josaa..It is conducted by CSAB..And as it is not conducted yet, hence eligibility criteria for this year is not yet available,but by the eligibility criteria of previous year,it can be said that you have to give JEE Mains entrance exam for participating in Spot round.

• If you didn't get seat and jossa regular 1 to 6 round then you are eligible
• If you are also get the seat in the josaa regular round 1 to 6 if you are already have a allotted seat then also you are eligible for csab special round
• if you are allotted seat in round 1to6 but you forget the reporting and may not have paid the seat acceptance fee is and not have reported then you are also eligible for special round CSab.

hope it helped.
