Colegio de Belén
As children, the Castro brothers were expelled from the first school they attended. Like Fidel, Raúl later attended the Jesuit School of Colegio Dolores in Santiago and Belen Jesuit Preparatory School () in Havana. Raúl as an undergraduate studied social sciences. Whereas Fidel excelled as a student, Raúl turned in mostly mediocre performances. Raúl became a committed socialist and joined the Socialist Youth, an affiliate of the Soviet-oriented Cuban Communist Party, Partido Socialista Popular (PSP).
