Hi Akansha,

Bharti and Kalindi are all girls' colleges while Ramunajan is a co-ed college. All of these are average and decent colleges for arts courses and have good faculty. Ramunajan would be the best one in terms of infrastructure, as it has recently developed at a fast pace. It is located in Kalkaji. 

Bharti and Kalindi are located in Janakpuri and Patel Nagar respectively. You may choose based on your priorities like location, infrastructure, girls or co-ed etc. At the end, it is DU you are graduating from that matters.

Had I been at your place, I would have preferred Ramunajan over Kalindi over Bharti college.

All the best!
