Hey aspirant!

As of now, it is difficult to predict the actual qualifying NTA score for JEE Advanced eligibility. However, according to many experts and the predicted cutoffs, if you have a percentile above 85-86 then you have a decent chance to qualify. Also, you can refer to the previous year JEE Main qualifying cutoff scores by NTA as follows to understand your chances:-

Common Rank List (CRL)

89.7548849

GEN-EWS

78.2174869

Other Backward Classes (OBC-NCL)

74.3166557

Scheduled Caste (SC)

54.0128155

Scheduled Tribe (ST)

44.3345172

PwD

0.11371730

Therefore, looking at previous year's trends it is a big possibility that you would qualify for JEE Advanced.

So, try on concentrating on preparing for Advanced and keep your preparations on track for it.

Also, you have another opportunity to improve your results by performing better in the April attempt and I would advise you to concentrate on that too to boost your chances of getting the desired colleges.
