Between Calcutta University and Presidency University for a PG, you should opt for Presidency University. Having studied in Calcutta University, I suggest you go for Presidency instead.

• Calcutta University is known to provide low marks to students.
• The teachers are part of the board or question setter which doesn't give good marks and a student has to study under them.
• Apart from this, there are certain colleges that, to improve their grades, give good marks to the students.
• Both of these cases are not good. Along with this, the marks get worse as the answer sheets are not checked by the college faculty and are instead checked by someone else.
• The Presidency won over these things. A student scores good marks in Presidency.
• The teachers are not that strict and they only check the answers sheets.
• As it's only the college teachers who do the questions and answers work in the exam, once getting familiar with them will help a student score well.

Therefore, it's better to opt for Presidency University. Due to its better faculty, facilities and overall experience.

You certainly can. If the registration process is completed by you already, make sure you take your TC and mark sheet from there. Your mark sheet should have an "admission canceled" stamp to it otherwise it would not be approved. You may also be required to write a letter sent to the authorities. It will cost you a sum of ?1000-1500 which would have to be deposited as a TC fee.

In case you have missed your registration, make sure you get in touch with the staff of the office. They will help you get your admission canceled.

Although this is a rare situation, in case you are lucky, they may give back your admission fee too.

No, there is no uniform at Presidency University. Being a student at Presidency University, I can assure you that there are no strict rules considering clothes.

In University your nature matters more than what you wear. Decent clothing at the campus is expected and how you carry it.

At Presidency University nobody wears a uniform as told by the authority and it is expected to continue further too.

Therefore, there is no uniform at Presidency University. Students are free to wear whatever they want. But to maintain decency at the university campus by wearing decent clothes.

No, Presidency University Bangalore is entirely different from Presidency University Kolkata. The key points of difference between the two institutes are stated below in the following points.

• The Presidency University at Bangalore is a private university, which was newly established in 2013. But, Presidency University, Kolkata is a 200-year old premier institute. 
• Presidency College became a university in 2010, even before Presidency Bangalore was established. It is now fully funded by the government of West Bengal.
• In Presidency University, Kolkata, many eminent personalities studied during their era. For example, Prof. S. N. Bose, Netaji Subhas Chandra Bose, Dr. Rajendra Prasad (India’s first president), Satyajit Ray, Prof. M. N. Saha, Dr. Amartya Sen (Nobel Laureate in economics), etc.
• The list of professors of Presidency University Kolkata has several pioneers including Sir J. C. Bose (father of the modern semiconductor radio), Henry Derozio (Bengal Renaissance pioneer), Prof. P. C. Roy (Chemist), Prof. A. K. Roychoudhury (invented the Roychoudhury’s equation for GTR), Dr. P.
