Assam

Hey Shahidul,
I researched some of the universities in Assam. The first one I saw is department of mass communication and journalism, University of Gauhati which is the number one of all. Then there are:
-Department of Mass Communication, Assam Down Town University
Fees: 1 to 2 lakhs
-Krishna Kanta Handique State Open University
-Dibrugarh University: Centre for Studies in Journalism and Mass Communication
-Asian Institute of Management and Technology (AIMT)
You can try in these colleges.
And, if you still have some questions in your mind, you can ask!

Dear,
You can join BBA without any hindrance.
All the best.

Dear Harimohan,
The following colleges are the best, offering BBA course:
1. International Institute of Management and Technical Studies, Guwahati, Guwahati
2. Indian School of Business Management & Administration, Guwahati, Guwahati
3. NIS Academy, Dibrugarh, Dibrugarh
4. Dispur College - Gauhati University, Guwahati
5. Golaghat Commerce College, Assam
All the best.

You need to check that Bombay University has its study center near your place. If yes, good, otherwise, you can also opt for IGNOU.

The fee structure for different institutes is as follows:
Assam Down Town University, Guwahati , INR 1,00,000
Royal Group of Institutions, Guwahati INR 4,11,000
All the best.

There is no IIIT in Guwahati. IIT - Guwahati is available.

Akash Institute is the best coaching institute in Assam.
All the best.

You cannot get admission presently, you can now apply for 2017-18 year. It is a decent college, but not with great brand reputation and neither amongst rankings.
The admission procedure is given in the below link:
