which is good for b.tech mechanical engineering either NIT Tiruchi or NIT Warangal
If you are getting mechanical engineering in Nit Trichi you should definitely go for it.
Infrastructure wise and placement wise both are good.
So, I would recommend you to go with Nit Trichy.
But if your home is near Warangal you can also go for it.
