One of my friends studied at Presidency College, Chennai. According to her it is a good institution but has average facilities.

• The faculty or teaching staff are highly experienced. 
• The course curriculum is also good.
• At present staff are outnumbered and there is a lack of teachers. 
• Students do not have a dedicated classroom, both PG and UG students keep shifting from one room to another to attend class because of the lack of a department dedicated room. 
• There are two classrooms with good facilities, but the other two rooms lack seating facilities. It is very difficult to accomodate 40 students in those two rooms.

It is suggested that you do not join the Presidency College, Chennai, rather than look for other more reliable options.
