i think you have misunderstood.Aiims pg 2020 exam is merged with NEET pg 2020 which will be from now on called NEXT exam which is entrance exam for pg. Although,there hasn't been any official announcement regarding this issue .So for now admission in aiims will be carried out by it's exam only and not neet.

Hi, 

Neet and aiims can't merge ever.  Neet fill the all over India medical government and private colleges seats through its entrance exam. That is 65000 + seats

And on other hand aiims fulfill its 1207 seats in aiims medical colleges only. 

There is chance that aiims and jipmer can be merged but it will be also difficult. 

You will get updates when any change will be done. 

For any other information you can ask us.
