Hello Aspirant,

Unfortunately, now you cannot get the seat allotted in JOSAA 6th round because once you enter the CSAB special round counselling then you are no more eligible for any allotment of JOSAA that had allotted to you earlier. So now you have only option either leave the CSAB counselling and try for other state counselling or the seat whichever is allotted to you, accept it or if you want, you can take a drop as well if you are eligible for JEE-Main 2022, the eligibility can be checked by the link given below :-

You can read more about CSAB counselling from the article given below  :-

CSAB 2021 Registration (Started) - Dates, Fee, Documents, Choice Filling, Reporting, Seat Matrix (careers360.com)

I hope this information helps you.

Good Luck!!
