Hi Sravya,
Congrats on your list of acceptances, that is excellent!! Certainly lots to consider, and Brown or Erasmus sound like great options. CASS has a solid reputation too. Here are some things to look at as you research and compare your options:
-curriculum differences; what classes are required, what electives are available, which program's options appeal to you most?
-special projects, internships, other program details, travel etc
-TALK to students at each!! ask to be put in touch with a few students (just ask admissions)
-look at the CLASS PROFILE that is typical, what nationalities, what industries etc do people come from as you learn a lot from those in your class
-look at class size
-ask about alumni programs
-look at employment stats just for a rough gauge even though you're going back to the family biz
-look at clubs and on-campus activities
-research what each CITY and campus is like!
Hope that helps, good luck and keep us posted!
