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.
