After Round 1, all of the 1900 seats of AIIMS have been filled up. Almost 80% of the Candidates reported to the Colleges and those opted for Upgradation and vacated the seats, they were allotted to others in Round 2. And it is pretty much the same with JIPMER too. If you opted for Round 1 or Round 2 counselling and didnt get a seat in AIIMS or JIPMER, it is little surprising. Now we are yet to see how the Mop up round seat matrix looks like. Now it depends on the vacant seats available and as this is the very first time that AIIMS and JIPMER are conducting admission to their respective Institutions through NEET score, it is difficult to predict these. In general, AIIMS Conducts stray vacancy round for vacant seats and this year as well, there is a stray vacancy round scheduled for  both AIIMS and JIPMER. But then until last year, as there was an entrance examination, the qualified lot was less. But this year. it is slightly different. So to be honest, it is difficult to predict. But in the Mop up round Choice filling if it shows AIIMS or JIPMER as options, you should certainly fill them up as your options and put them up high in the order.
