my mains 2019 rank is 34000 in Open and 8340 in OBC category. Can i get civil or EEE or mechanical in trichy NIT ?

Jee main mark is needed for NIT,IIIT colleges.
You caun't get electrical and electronics engineering, mechanical engineering in national institute of technology tiruchirappalli whereas you can try for civil Engineering at national institute of technology tiruchirappalli but it has so less chances.
Expected cutoff for national institute of technology tiruchirappalli:

• General - 81
• OBC-NCL - 49
• Schedule caste - 32
• Scheduled tribes - 07

Hello! Aspirant

Seeing your score and previous year cuttoff of NIT Trichy,you seem to have less chance of getting mecjmechan engineering in NIT Trichy with home state quota and OBC quota.You need rank under 4k with OBC quota.You can fetch other stream seat in NIT Trichy under HS quota.

Ask for query.

GOOD LUCK!
