Hi Aspirant

All these options are great options.

Since you have no specific interest in any particular branch it comes down to picking up the right college.

There are a few things that must be kept in mind while choosing the college:

a) Alumni Network - The older the college the better Alumni Network  youw have and that helps a lot. In that case IIT Roorkee will be the best option for you.

b) Location - You must keep in mind that location plays a very major role. In case you decide to go for higher studies you must see which city will give you better opportunities for coaching.

c) Ranking - Going by the NIRF Rankings, the order would be IIT Roorkee then IIT Guwahati then IIT BHU.

Hope this helps. All the Best.
