12 months and was compulsory for all French students; the abolition of draft in France made this requirement of Polytechnique somewhat anachronistic, and the service was reformulated as a period of "human and military training." All French students spend a month together at La Courtine in a military training center. By the end of this month, they are assigned either to a civilian service or to the Army, Navy, Air Force or Gendarmerie. Students who are assigned to military service undergo two months of military training at French officer schools such as Saint-Cyr or École Navale. Finally, they are assigned to a wide range of units for a five-month tour of duty in a French military unit (which may include, but is not limited to, infantry and artillery regiments, warships, and air bases). While French students remain under military status during their studies at Polytechnique, and participate in various ceremonies and other military events, such as national ceremonies like Bastille Day or the anniversaries of the armistices of the World Wars, they do not undergo actual military training after completing their first-year service. They receive at the end of the first year the full dress uniform, which comprises black trousers with a red stripe (a skirt for females), a coat with brass buttons and a belt, a small sword and a cocked hat (officially called a bicorne). French-speaking foreign students perform civil service. Civil service can, for example, consist of being an assistant in a high school in a disadvantaged French suburb. Then begins a four-month period during which all students take the same five courses: Mathematics, Applied Mathematics, Physics, Computer Science and Economics. Second year The second year is a year of multidisciplinary studies. The set of disciplines covers most of the scientific fields (mathematics, applied mathematics, mechanics, computer science, biology, physics, chemistry, economics) and some areas of the humanities (foreign languages, general humanities...). Students must choose twelve courses in at least five different disciplines. Third year In the third year, students must choose a specialization (programme d'approfondissement), which often focuses on a discipline or sometimes an interdisciplinary subject. This year ends with a research internship (four to six months). Students also earn a Master's degree in engineering, science and technology in their third year. Fourth year The fourth year is the beginning of more specialized studies: students who do not enter a State Corps must enter either a
