Hello,

It is very difficult to judge the percentile as it differs relatively every year as per the overall performance you need to score more than 99.00 + percentage of the population appearing for the test along with you, in order to score 99.00 + percentile in the exam.let’s assume you score 90 out of 180. You have scored 50 percent.

If 99.99 percent of the total candidates score less than 50, you have achieved the 99.99 percentile. 

however over the years it has been noticed that o

out of 180,  your scores should be around 160+ as ATMA for getting 90 + percentile 

hope this helsp you !

all the best !
