Hi Aspirant
A lot of students face this kind of dilemma during JOSAA counseling.
The most important point that must be kept in mind is going for a branch that interests you more. Try to gather as much information as you can about these branches from the internet and the people in these fields.
The choice between an old IIT and a new one is a difficult one to make. You must weigh the pros and cons.
Indore being almost in the centre in the nation and a better city than Roorkee in terms of opportunities for coaching for higher studies will be the better option if you want to pursue higher studies.
As far as rankings from various organisations go IIT Roorkee would be the better option. But IIT Indore is also growing at an amazing pace.
As far as Branch Change is considered , it is relatively easier in the new IITs than the old ones due to the number of students.
But in some IITs like IIT Hyderabad, branch change also depends on the branch you have taken and is much easier in branches like chemical engineering and civil engineer.
Hope this helps. All the Best.
