Good day, I'm a Mexican student who is currently in his 3rd year of Junior High School; from an early age I have shown some inclination towards Mathematics and Science (especially Physics). Within a few months I will finish Junior High School and I'm planning in enrolling in the International Baccalaureate program at a prestigious High School which can offer me a ~40/50% scholarship (which is the maximum scholarship that they offer to small schools like mine). Recently I have been thinking about the following questions: Should I make my undergrad studies in a Mexican University (UNAM or IPN) or shall I study in another country? In case I study in another country: approximately how much does a semester on a U.S. university cost (something like Berkeley or MIT)? In case I make my undergrad studies in Mexico: would it be recommendable for me to make my graduate studies (M.D. and Ph.D.) in another country? Thanks for your attention, Patrick.
