Dear aspirant,

According to your question and taking into consideration that you have got 20926 in jee mains 2017 and that too in general category so i would start with the topmost nits-

In nit Trichy you get branches like metallurgy and production if your home state is tamil nadu but if not there is no chance.

In nit wanragal and surathkal same case applies as the cut off for these are almost at par.

In some lower nits like goa,Arunachal Pradesh you can get some non core branches.
