One concern I have is regarding research I need to do on schools. How much research do I need to do understand the schools really well? For example, from Duke's website and brochure I felt that they value team approach and extracurriculars as a way to learn about leadership and team dynamics. Since I am an international applicant, visiting these schools is not possible for me. Hence, I need to rely on information available online.
Is this research enough? Do you think there is a significant difference in school cultures? I might be equally happy to get into Duke or Cornell. Is this because of my lack of awareness of difference in cultures?
