Congrats! I heard Insead is very generous with their financial aid.... Someone once told me that if you have spouse or children, they will give you more... Not sure how true this is.
btw, which campus you applied to ? I found that the admission process of Ph.D. program in INSEAD is so random, since the marketing program won't have their interviews until 3.17-3.21, while some other programs already have their decisions.
