This year the Marks are going to be a little higher than previous years.
For e.g
Last year 70 normalized mark got rank about 50
this year in the app itself 70 normalized mark already has 69 students.
So, the pattern is quite evident.
Rank would be a little lower for what a person got on the same normalized marks last year..
Earlier the rank estimate was done based on previous year stats.
To account for the thing mentioned above, the rank estimate range has been widened.
