Hello Aspirant ,

Mop up rounds come towards the last in the counselling process. All the vacant/non-allotted seats or resigned seats from the two rounds of counselling are will come under the mop-up round. You can appear for the All India counselling , get a seat and in case it is not want you want, or you get better options in the state counselling , you may leave the AIQ seat. The dates of both these never clash hence that won't be a problem. And when it comes to mop -up round, there are some rules. Those candidates who got admitted in 1st round & 2nd round and secured the admission but not filled status retention form or got wait-listed or  who were not given options during the first two rounds are the only one who will be allowed to attend the mop-up round . Candidates who are not eligible would be :

-Candidate to whom a seat has been allotted in computerized CAP rounds and not joined.

-The candidate who has filled the status retention form.

-Those candidates who are joined and resigned after allotment of seats in previous rounds.

-Those candidates who are joined but not working in the institution.
