Hi,

Considering that the exam for 17th March shift 2 was moderate your expected percentile will be around 90.99 - 93.45 and your corresponding rank on the basis of these percentiles will be around 103615 to 65984.

Now, on the basis of this rank and considering that you belong to general category, according to previous year cut offs for NITs your chances aren't that much. Still you have two chances left so, work hard for them.
