Hello Aspirant,
33 is a good enough rank in the waiting list of NERIST.
Usually it cannot be predicted if you will get a confirmed seat or not because it depends on how many students in yhe merit list confirm their seats. However, there are still quite good chances of your admission.
Thus, I suggest you to atleast attend the counselling to ensure that you do not get missed out just in case they reach upto your rank.
