Dear student,
To get into iisc bangalore you need to score a rank below 5000 in jee advanced if you are from obc category according to the cut off of the year 2019, however cut off can vary from year to year.
To know more about the admission process you can check the link given below:

Hi.

Cutoff rank for IISC through JEE Main in OBC Category was 20,000 in Spot round 2 in 2019.

In 2020 currently, it is 12000 in Spot Round 1 for OBC.

Now percentile approximation is not accurate as it is effected by many factors, but roughly you can get 20000 rank at 93 percentile so it is better to get above 94 percentile to ensure your admission.

Best of Luck
