We have a choice between BVN and Bluebells. Though BVN was always a preference for me the rankings suggest Bluebells in top 17 delhi schools in the last two years.
Also south delhi schools ranking says Bluebells is 2 and BVN is 7 (gyan bharti is 5!).
Not sure how trust worthy these ranking are (Hindustan times). And also we have already paid fees in Bluebells.
