Hello,

I would be telling about NIT,Trichy.

Here, as per your expectations, it would be around 15000-25000 AIR.

However, this may change as there are many factors affecting this.

Now coming to the courses.Here, you may have a chance at Civil engineering(less chance), metallurgical engineering and maybe production engineering.

I would also suggest you to viist the career360's link mentioned below to get an detailed idea about the cutoff.

The link for the same is:https://engineering.careers360.com/articles/jee-main-cutoff-for-nit-trichy

Hope this helps and all the very best!
