Hello,

In simple words your percentile score depends a lot on the performance of all the students appearing for the exam. Considering the competition, 65 percentile isn't great, but there's nothing to loose hope you'll get another chance. On a comparison basis a percentile of 95 can be compared to a rank of somewhere around 65k which is enough to clear the cutoff for jee advance but will not fetch you a seat NIT(general candidate). So a percentile of 97 and above has chances of getting an NIT or IIIT.

I think this would be helpful for you to gauge your performance.wish you all the best for your next exam. 

Hello,   

If you have scored 65.6867510 percentile, then it means that you need to put in more efforts and give a try again, because, with this percentile, there is a  little have a chance at NIT colleges.
