hello aspirant,

See it is very difficult to predict the percentile score needed to get a rank within 7k in JEE Advance, This is because the JEE advance cutoff varies for every year and it depends on various factors like :

Difficulty level of the paper, previous year Cutoff trends, number of aspirants appearing, etc.

However, looking at the previous year Cutoff trends for JEE advance, you have to score around 190-220+ marks in the JEE advance paper to get a rank of within 7000 in JEE advance. Equivalently with a score of more than 95 percentile score you can get a 7K rank in JEE advance.

Further, please note that the above prediction is totally based on the previous year data which may vary this year as the Cutoff Varies bound to change every year.
