Hi,

This will also depend on whether you have the state quota or not as cutoffs vary according to it.

If you don't have the state quota, then to get ECE there, by looking at previous years' cutoffs, you should have a rank around 400-800 (marks 251 to 300).

However, with state quota, there are entirely different cutoffs which you can check at this site-> https://engineering.careers360.com/articles/jee-main-cutoff-for-nit-trichy
