are offered a placement at the university. Since UFRGS is free of charge, the Vestibular is usually a very hard examination since there are many candidates for few open placements. Examinations take place in January and classes begin in March. ENEM The Federal University of Rio Grande do Sul, as well as the other Brazilian federal universities, adopted the National High School Examination (ENEM) in 2010 as a standard of admission. The applicants’ participation in ENEM is optative. Initially, their performances in the examination were analyzed together with their performances in the university entrance exam, comprehending 10% of the final grade. However, as of 2019, UFRGS decided to withdraw the sum of 10% in the final score, having only vacancies through the National High School Exam (30%) and/or through the Vestibular (70%). Quality of education According to the ranking sponsored by the Ministry of Education (MEC, Ministério da Educação), UFRGS is Brazil's best university (in a ranking which doesn't include Universidade de São Paulo—see rankings of universities in Brazil for details). According to the Webometrics Ranking of World Universities in 2012, UFRGS was placed 71st worldwide. Notable alumni This is an incomplete list of famous UFRGS alumni, sorted by Faculty.
