Hello mohit.

VIT has there own values, and if you got a 91 percentile then congratulations for that and at 91 percentile, i think you will get a admission in vit pune and just go for counseling, you will get in vit pune. Last year my frnd got admission in vit pune at 90 percentile in CS branch. Its also depends on your branch, in which branch you are intrested.

It will be difficult to get admission in CS branch.

All the Best.
