No. Rabindra Bharati University (RBU) and Vishwa Bharati University are not the same. They are two separate universities. 

RBU is a state university whereas Visva Bharati is a central university. They are not related to each other in terms of administration but share the same ideologies and culture. 

RBU main campus is situated in Jorasanko, the ancestral house of Rabindranath Tagore. Visva Bharati was founded by Tagore in an estate of Bolpur owned by his father Maharshi Debendranath Tagore.

Choosing between Rabindra Bharati University (RBU) and Calcutta University (CU), is not justified, as they are both reputed institutions and have more or less the same performance. 

Their curriculum will be different, along with their teaching style. But both will provide you with similar opportunities after graduation.

CU students claim that it is very difficult to score good marks here, but since the semester system started in CU, it has become manageable. 

So choose the college you feel suits all your requirements, then go for the one. The one thing better in CU is the environment, because RBU has been in constant disputes and political turmoil, which sometimes hampers regular classwork.

Comparing universities is not a very good idea. Calcutta University (CU) and Rabindra Bharati University (RBU) are reputed institutions.

• The faculties here are well experienced but not punctual, they often leave most of the topics for the students to figure it out themselves.
• The administration of these institutions are slow and most of the time do not cater to the students' demands.
• Students who genuinely wanted to learn something will be disappointed, as seeking knowledge is not encouraged.
• Students are said to mug up theories than to actually understand the concepts. 
• Booth colleges are infamous for their scoring system. Students claim their answer sheets are not checked properly.

So, if you are willing to study in any one of the institutions, you should remember that your effort and dedication will finally matter and not the name of the college.
