Colleges in Uttarakhand

I think you should go and visit ICFAI University. Don't go just by the name. There are too many good colleges in Rajasthan, especially in Jaipur which are trying to compete with VIT Vellore, MNIT and LMNIT in terms of modern educational concepts, association with renowned universities in UK, USA, Canada and Russia sending their students in these institutions to compete globally, providing multidisciplinary expertise, opportunities for START-UPS their innovative ideas. In addition, they are providing project based learning from 1st semester and flexible-slot based time-table. I think you must visit some of the college in Jaipur specially Anand International College of engineering before making any decision. Please share your experience. All the best.

The two options you gave, I would advise you to go with electrical engineering at IIT(ISM) Dhanbad. It is because your branch matters and certainly electrical is much better than geophysical and electrical is core branch too.
Electrical engineering students at IIT(ISM), Dhanbad has got decent placements in past few years. Since we got the IIT tag last year only, the number of companies visiting the campus is bound to increase from here on. You can check out the placement records at the official website of IIT(ISM) IIT (ISM) - Training & Placement. Also, non-core companies are visiting our campus for all branches such as Capgemini, Goldman Sachs, etc.
And, if your college matter to you, we are not a bad choice there too. Yes, IIT(ISM)-Dhanbad is not among old IITs but it is older than all the old IITs (established in 1926). The infrastructure is quite good and lots of things are coming up. It has a rich legacy and culture of its own and most importantly it has a very strong alumni base throughout the world. If you are interested in higher studies after graduation this alumni base helps a lot no matter from which department you are.
All the best.
