Northwestern SESP?

Hi! I really love NU and I a considering applying ED. I am very interested in the Human Development in Context major, which is in SESP. I have a strong background in science, service, and other activities that involve working closely with others who come from different backgrounds from me; these extracurriculars line up nicely with the HDC program. However, I have heard that the SESP program is small and therefore very hard to get into. I was wondering if anyone had any insight on this? Does anyone know how many first-year students they accept/how many people apply to SESP, etc? Thanks!
