I'm currently a Computer Engineering undergraduate student at the State University of Campinas (Brazil), and according to Times Higher Education World University Rankings, my university is ranked second best in Latin America. I'm considering to pursue a graduate level education on a top-tier american university. Brazilian universities don't have GPA, but they do have class ranks to show academic performance. I'm currently in position 25/93 (top 27%), and I've seen that some institutions look for students who are top 5 or 10% in their class. I would like to know if the graduate admissions office will take into account the fact that my university is one of the best in Latin America, thus it's much more difficult to achieve top rank because my classmates are Brazilian elite students.
