You have just made it to the next round JEE Advanced but unfortunately at 69 percentile, you won't get any NIT or IIIT.

There has to be some mistake else it's not possible to have a mere 46.7percentile at 138 marks. If you have really got 138 marks then for sure you'll get a NIT. But if your actual score is 46 percentile then you won't get any NIT or IIIT. And please recheck your marks you may have had make some blunder while calculating your marks, else on an easy note your percentile should be around 95-96 if your score was 138.

At your rank, you won't get any NIT. Actually the thing is JoSAA colleges don't have that many seats reserved for Gen-EWS candidates so unless you don't make it under 5000 general EWS rank, you won't get any significant advantage.
