College student being shown on rank list under school category?

In the rank list for June Challenge 2020, under the category of Indian school students
a college student is shown occupying the third position, here is his Codechef profile

Maybe a fault in the database. I hope @admin looks into this matter as soon as possible.

Note: I am not demeaning anyone.

Thanks for reporting.
They have changed their institution after the contest began. The ranklist considers only the institute which was given when the contest started.
We’ll look into this.
