Hello Sree

Predicting marks required by you to get a seat in AIIMS Rishikesh or any other AIIMS is a bit difficult

This is because ,

It is the first time ever when AIIMS will be conducting admission through neet ,

Moreover, cut off marks  will depend upon various factors like toughness level question paper ,kind of marks scored by students etc

Also very limited are there in AIIMS and the competition is huge for Aiims .

considering these things,

You should target at least around 630-650 marks in your neet examination if you want to get a seat in Aiims Rishikesh if you belong to obc category

Thankyou
