what the hell is top 20 percentile if a student is in top 20 percentile then he have been definitely scored 75% above
Good Morning
In the JEE Main and Advanced , the minimum requirement of top 20 percentile means that you are in the top 20 percent of the respective board. In simple language , some boards have very strict marking criteria . So, the top 20 percentile cutoff will be far below 75% like for Odisha board in 2017 it was 331 marks out of 500.
Hope you found the answer useful.
All the best
