Hello j apprao,

As your son secured 65 percentile in the jee main it is good

The NTA-national testing agency

All the best

hi j apparao,

with percentile ranging from 74.13 to 64.11, the marks lies between 47 to 38.

percentage is your marks out of a total of 100, whereas percentile score of a candidate reflects percentage of candidates scoring below a particular candidate in that exam.

hope it helps!
