Assuming you are a General Category Non Tamil Nadu Student, you should target atleast 98-99 percentile in JEE Main, to secure your seat in either Metallurgical, Civil, Instrumentation or Production at NIT Trichy. However, you do have some relief in cutoff, if you are a Domicile student, however 98 Percentile must be your threshold, for better branches at NIT Trichy. Ideally in case of Domicile General Student, you can get either of the above branches at anywhere around 96.5-97 (35-38k AIR) percentile by Last Round of Counselling considering the latest 2020 Cutoffs.
