There are many colleges in DU which are very good for B.A. Hons. But Among all Hindu college and St. Stephan college comes on top. Followed by other good colleges like hansraj college, sgtb khalsa college, sri Venkateswara college, kirorimal college, ramjas college, lsr college, Jmc college, Miranda college. Also I am a sri Venkateswara college student so I suggest you to go for north campus or some good off campus rather than south campus because accommodation and travelling is so hectic in south campus.
