Educational infrastructure

Universities are composed of Faculties sometimes spread over several campuses. Classes are given Monday through Friday.
There exists in several universities a concept of "social service" that is necessary in order to obtain a professional degree. It consists of practical work in a community using the knowledge acquired during formal training. This generally takes place once a student has earned 80% of the course credits necessary for the degree.
Certain universities have programs, such as the University of Guadalajara's "UNICO" program, that last two years and allow students to work and study at the same time, with enrollment throughout the year.
