All 9th graders are taught the same classes nationwide, with minor differences in certain cases. These classes are: Turkish language, Turkish literature, mathematics, physics, chemistry, biology, geometry, world history, geography, religion & ethics, physical education, a foreign language (in most cases English), a second foreign language (most commonly German but could be French, Italian, Japanese, Arabic, Russian, or Chinese). When students enter the 11th grade, they typically choose one of four tracks: Turkish language–mathematics, science, social sciences, and foreign languages. In vocational high schools, no tracks are offered, while in science high schools only the science tracks are offered. Different schools may have different policies; some, but not many, schools offer electives instead of academic tracks, giving students a wider range of options. For the 10th, 11th and 12th grade, the compulsory courses are: Turkish language, Turkish literature and republican history. In addition to that, students may be taught the following classes, depending on the track they choose and/or the high school they attend: mathematics, geometry, statistics, physics, biology, chemistry, geography, philosophy, psychology, sociology, economy, logic, arts and music, traffic and health, computer, physical education, first and second foreign language. The students used to be given a diploma for the academic track they had chosen, which gave them an advantage if they wanted to pursue their higher education in the corresponding fields, as the University Entrance Exam scores were weighted according to the student's track. (e.g. A science student would have an advantage over a Turkish-Mathematics student when applying for Medicine). As of the 2010–2011 educational year, all high school students are given the standard high school diploma. At the end of high school, following the 12th grade, students take a high school finishing examination and they are required to pass this in order to take the University Entrance Exam and continue their studies at a university. There are four score types for different academic fields, including but not limited to: Turkish language–mathematics: international relations, law, education, psychology, economy, business management, and similar. Science: engineering, computer science, medicine, and other science-related professions. Social sciences: history, geography, and education. Foreign languages: language/linguistics and language teaching. International education The International Baccalaureate has been available in Turkey since 1994 when the first school was authorized by the IB and 53 schools now offer one or more of the IB programmes. Vocational education Vocational and technical secondary education involves the institutions that both raise
