NIT Trichy is one of the top NITs so you will have to secure a good rank in Jee Mains. Considering general category, 250+ score is enough to admit in NIT Trichy. For OBC students, There is slightly less score to need like 230+ and 180–190+ score need for SC, ST students. It may be vary depending on question paper and cutoff rank.

I will strongly recommend you that instead of worrying about cut-offs of any college right now you should focus on your examination which is going to be held from 8th April - 16th April. If you give your best and score very good in the JEE Mains then you can get admission in not only NITs you can even become eligible for JEE Advance. So, focus more on it right now. You will get enough time later to analyse all these cut-offs after you get the JEE Mains result.

Feel free to ask if you have any more queries. All the best!!
