Hey

With the percentile mentioned above, you rank must be in between 18000 to 18500. When talking of, HBIT there are chances for you to get into the IT branch of the particular college as the cut off is higher than your predicted rank which will let you get the admission easily. You are also eligible for the CS branch. But since the cut off is close to your predicted rank, it might get a  little difficult to acquire seat. You are still eligible in apply for both CS and IT branch though.

Below I'm providing a link for you which might help you know about the college in detail. Do check.
