Hello Aspirant! The NTA Score given at the end of your JEE Main result is your percentile. It's given in decimals so as to differentiate the ranks of lakhs of students giving the exam. So if your NTA Score is 62 then your percentile is also 62 with some more numbers after the decimal. Your rank will be given after all the results are out, that is before the JOSAA counselling. It will have two ranks of yours, one CRL rank that is your General rank and other Category rank that is your SC Category rank.

So your JEE Main 2021 percentile is 62.
