Books for finding more about schools

go to https://essaysnark.blogspot.com. They sell strategy guides for applying to top schools. I believe they have ones for HBS, Stanford, Stern, CBS, Kellogg, Tuck, etc. The guides include a lot of the information you are seeking. Also much of what you want to find can't really be communicated in a book or a website, alone. You need to talk to current students. I suggest that you go to each school's website that you're interested in and look up the student clubs. They should each have a contact email address. Pick one or two clubs that you'd be interested in (maybe one professional, one social) and reach out to them. Tell them you are a prospective applicant and want to learn more about the school's culture, professors, and student life. Someone will get back to you. Hope this helps.
