Hello,
Let me tell you that in 85 percentile it is not possible to get the top level nits like Jamshedpur, durgapur, Silchar, allahabad, rourkela, Calicut, Trichy, warangal, surathkal.
However various factors are considered while deciding the cut offs like number of candidates appearing in the examination, number of vacant seats in college, previous years cut offs and difficulty level of the paper.
