Hello student.

81.76 percentile is really a good one. But at the same time IIIT gwalior is an institution which has higher competition. every year there will be many number of students applying for this college.

These are the opening ranks and closing ranks of the institution in the year of 2018. So with this percentile, it might be difficult to get.

Here is how you can calculate rank:

JEE Main 2020 rank (probable) = (100- NTA percentile score ) X6,35,000 /100

where 6,35,000 are the number of people attended jee mains exam in the month of september.

So according to this, your rank is around 1,00,000

This is difficult to get through IIIT gwalior. I suggest you to apply for other colleges.
