Dear Vansham,
In case, you can get a chance in Hansraj College, go ahead without thinking much. Kolkata has poor student crowd. Moreover, the faculty of SXC has degraded. I don't know much about Delhi University when it comes to faculty, but given that most of the books authored by the professors of DU, sell like hot cakes all over in India, for all professional exams, I can easily assume, that the professors must also be pretty good there. SXC, however, teaches you one of the most important things in Life I. e. discipline. You wake up 5 AM and reach sharply by 6 AM. There are no excuses for securing low scores in examinations, and above all, you can easily work at any place, once college gets over at 10 AM.

Dear Kamal,
All three are good colleges in terms of studies, notably faculty of both the college has similar experience and subject knowledge.
You should do join Aurbindo College, if you live in South Delhi, and whereas in North Delhi, you should join Satyawati College.
Some Benefits to get in Satyawati College are:
Satyawati College has biggest Auditorium relate to size of other Colleges Auditoriums.
Satyawati College has best faculty in terms of Arts and Commerce in comparative of Campus colleges even.
We got one of the biggest library in University of Delhi.
Satyawati will be providing Hostel Faculty Soon
Thank you and wish you all the best in whichever college you are, do your best.

Dear Pulkit,
I would suggest you to visit all three campuses and decide for yourself. However, I can give you some insights of Aryabhatta College. Aryabhatta College is the youngest college is Delhi University, however that is not the case with its faculty. There faculty here is really good and have good amount of experience.
The college campus is pretty clean and the infrastructure is one of the best amongst other colleges of Delhi University because the building has been recently built. The environment is quite motivating and the students are working really hard to build a good reputation for the college. For instance, in a short span of two years, more than 10 societies have been formed and they are functioning quite well.
The college shares it's campus with Ram Lal Anand College. There are two canteens on the campus and food is pretty decent and quite cheap. The crowd is really good in comparison to the other Mentioned college.
The college is located in the South Campus along with colleges like Motilal Nehru, Venkateswara and ARSD. The closest hangout point is the very famous Satya Niketan where you can spend your days and never get bored. I would urge you to check out the colleges and choose in accordance with your convenience.
