Hello dear student, 

Greetings! 

I can't help you with the score required to get into NIT TRICHY as it keeps changing every year depending upon toughness level of question paper and number of students that appeared in the exam but I can surely help you with the rank you need to get.

To get NIT TRICHY you need to get under AIR 45 if you are from general as there are 92 seats in NIT TRICHY,  out of which 50% is for sc/st/obc . 

For obc candidate , one needs to get a AIR 100-130 to get NIT TRICHY. 

Thankyou 

Good luck
