Hey Aspirant,

First of all I would like to tell tell you that it's better to choose a good college over a good branch because if you are getting a good college but not the branch you want so you can get it changed after scoring well in 1st year. So according to me you should go for NIT Tiruchirapalli as it is top college among all the NITs. Plus it has a good Placement record of you are willing to continue in civil Engineering also.

I hope this helps !!
