The University of Buenos Aires (Spanish: Universidad de Buenos Aires, UBA) is the largest university in Argentina and the largest university by enrollment in Latin America. Founded on August 12, 1821 in the city of Buenos Aires, it consists of 13 departments, 6 hospitals, 10 museums and is linked to 4 high schools: Colegio Nacional de Buenos Aires, Escuela Superior de Comercio Carlos Pellegrini, Instituto Libre de Segunda Enseñanza and Escuela de Educación Técnica Profesional en Producción Agropecuaria y Agroalimentaria.
To enter any of the available programmes of study in the university, students who have successfully completed high school must pass a first year called CBC, which stands for Ciclo Básico Común (Common Basic Cycle). Only upon completion of this first year may the student enter the chosen school; until then, they must attend courses in different buildings, and have up to 3 years to finish the 6 subjects (which vary depending on the programme of study chosen) assigned in two groups of 3.
Each subject is of one quadrimester duration (March–July or August–November). If someone passes all 6 subjects in their respective quadrimesters, the CBC will take only one year. Potential students of economics, instead, take a 2-year common cycle, the "CBG" (General Basic Cycle), comprising 12 subjects.
