You said, that they accept 150 students outright! An absolutely correct statement. Hypothesis: These 150 students may be creme de la creme. They may have offers from Harvard, UCSF, Johns Hopkins, Wash U, Yale et. al.
Based on realistic probability data, a third of these 150, might not accept the offer, based on financial conditions,monetary packages offered, close proximity to home, offer from Harvard, Johns Hopkins etc., and various other reasons. This was explained to me by a friend of mine presently pursuing Ph.D in Statistics. If 86 seats are to be filled, 36 from wait list will have to be accepted. Based on this logic, my friend recommends that I must interview Stanford. I guess, I better listen to him and spend $ 700+ for this interview. I will get a chance to visit California again. A request to
AMCAS !!
Can they develop a program where I can line up all my interviews in one region. Cut my travel expenses down. This will definitely help the future generation.
