Big difference in student quality between HBS/Stanford and the rest?ST
A friend at HBS was saying that he felt the biggest difference between HBS (stanford would fall in this category as well) and the rest of the top schools is the amazing quality of the students. Not so much academically, but their work experience, life experience, accomplishments, background, all dwarf those of other schools.
He visited the schools he got into for their orientation for accepted students. And based on his interaction, he saw a very noticeable difference between HBS and the rest.
