Public expenditure of the GDP was less in 2002–05 than in 1991. Public education is theoretically free and mandatory for under-16-year-olds, but in practice, expenses exist. Net primary enrollment rate was 44% in 2005, much less than the 79% in 1991. The country has universities. Education between ages six and sixteen is compulsory. Pupils who complete six years of primary school and seven years of secondary school obtain a baccalaureate. At the university, students can obtain a bachelor's degree in three years and a master's after four. Marien Ngouabi University—which offers courses in medicine, law and several other fields—is the country's only public university. Instruction at all levels is in French, and the educational system as a whole models the French system. The educational infrastructure has been seriously degraded as a result of political and economic crises. There are no seats in most classrooms, forcing children to sit on the floor. Enterprising individuals have set up private schools, but they often lack the technical knowledge and familiarity with the national curriculum to teach effectively. Families frequently enroll their children in private schools only to find they cannot make the payments.
What do students who finish 13 years of schooling receive?
A: baccalaureate

Though the music varied widely between regions and artists, the post-punk movement has been characterized by its "conceptual assault" on rock conventions and rejection of aesthetics perceived of as traditionalist, hegemonic or rockist in favor of experimentation with production techniques and non-rock musical styles such as dub, electronic music, disco, noise, jazz, krautrock, world music and the avant-garde. While post-punk musicians often avoided or intentionally obscured conventional influences, previous musical styles did serve as touchstones for the movement, including particular brands of glam, art rock and "[the] dark undercurrent of '60s music".[nb 1] According to Reynolds, artists once again approached the studio as an instrument, using new recording methods and pursuing novel sonic territories. Author Matthew Bannister wrote that post-punk artists rejected the high cultural references of 1960s rock artists like the Beatles and Bob Dylan as well as paradigms that defined "rock as progressive, as art, as 'sterile' studio perfectionism ... by adopting an avant-garde aesthetic".
What were the things that post-punk really got into?
A: experimentation with production techniques

In 1934 the Zagreb Provincial Committee sent Tito to Vienna where all the Central Committee of the Communist Party of Yugoslavia had sought refuge. He was appointed to the Committee and started to appoint allies to him, among them Edvard Kardelj, Milovan Đilas, Aleksandar Ranković and Boris Kidrič. In 1935, Tito travelled to the Soviet Union, working for a year in the Balkans section of Comintern. He was a member of the Soviet Communist Party and the Soviet secret police (NKVD). Tito was also involved in recruiting for the Dimitrov Battalion, a group of volunteers serving in the Spanish Civil War. In 1936, the Comintern sent "Comrade Walter" (i.e. Tito) back to Yugoslavia to purge the Communist Party there. In 1937, Stalin had the Secretary-General of the CPY, Milan Gorkić, murdered in Moscow. Subsequently Tito was appointed Secretary-General of the still-outlawed CPY.
