The 44,200 students who, starting Wednesday, will be playing a part of their future in the university entrance exams have been preparing for this moment for months, in one way or another. At the same time, the wheels have also been turning for weeks to make the university entrance exams run like clockwork—or at least try to. This network includes everyone from the university entrance exam coordinator and the head of the University Admissions Office in Catalonia to 221 examining boards that organize 35 tests and, of course, the more than 2,400 teachers involved in the university entrance exams.
